Both here at BP (and in the annual) and at my other home, I've been waging a desultory war about Derek Jeter's future. His contract is up after the 2010 season, and though he'll be knocking on the door of 3,000 hits, I have argued that the Yankees should say goodbye. Jeter's defense is already a problem at short and is unlikely to have improved as he enters his age-37 season. With his bat sliding and his speed seemingly ebbing, a transfer to another position seems unlikely to bear fruit. As I said in my most recent chat, "I don't know that Jeter is a viable major leaguer in three years. My standard line—his glove will no longer play in the middle infield, his bat won't play anywhere else."

With 2010 in mind, I decided to go hunting through baseball history for those teams that put considerations of age aside and used a regular shortstop of Jeter 2010 vintage, age-37 and up. "Regular" here is defined by a season of more than 400 plate appearances. Before we get into the actual AARP all-stars, a note about the results. This group has an inherent selection bias. A shortstop only lasts into his late 30s because his defense was so good to begin with, or perceived to be so good, that the teams felt that they were still worth playing despite declining powers. Thus in the first group, the 37-year-olds, you will find that of 15 players, seven are Hall of Famers, two more (Dave Concepcion and Bad Bill Dahlen) are frequently mentioned as belonging in the Hall of Fame, and another (Omar Vizquel) may one day get there on the strength of his defense.

So far we have learned very little, except that Honus Wagner was a great player at any age. We've also learned that very few teams thought their shortstop was good enough that keeping him around at this age was a worthwhile thing to do, or that you can have a good record while doing it, and even win a pennant.

One change in this group resulted in a near pennant-winner the following season: after Dahlen's offensively inert season in 1907, the Giants switched to the more potent Al Bridwell. This and other key moves, including the return of slugger Turkey Mike Donlin from self-imposed exile, helped the Giants improve to 98-56 and a controversial second-place finish (for more, see our book It Ain't Over).

Moving our age cut-off up by a year, we find that in the entire modern history of baseball, just 12 teams tried to compete with a 38-year-old shortstop. Again, the implication seems to be that unless you have one of the top shortstops of all time—or Bones Ely, who our translations suggest was a defensive standout in his day—the younger guys had more range.

There are two strong teams here. Honus Wagner's 1912 Pirates won at a .616 percentage, good enough for a pennant in many seasons, but were simply outclassed by a Giants team that won 103 games. The Flying Dutchman was clearly part of that team's assets. Less clear-cut is the case of Larry Bowa and the 1984 Cubs. In January, 1982, the Cubs and Phillies had consummated the infamous Bowa/Ryne Sandberg-for-Ivan DeJesus trade, a swap of shortstops in which the future MVP second baseman was a throw-in.

Bowa was never much of a hitter, but his already weak bat flat-out flatlined in 1984. Nonetheless, the Cubs won the NL East in a season in which just about everything went right. The Cubs have fooled themselves about many things over the past century, but Bowa wasn't one of them—they tried to replace Bowa with Shawon Dunston, the first overall draft pick of 1982, as soon as the next Opening Day, but Dunston struggled during the first month and was sent down until August, at which point Bowa was released. He was signed by the Mets, who were perhaps hoping that the five-time All-Star and two-time Gold Glover would inspire Rafael Santana to greater range afield. It wwas not to be, and Bowa's 16-season playing career was over.

Note that the last three seasons of Louis Aparicio's career, spent with the Red Sox, are represented here. As a hitter, Aparicio wasn't far off from the center of his career, which is to say that he still couldn't hit, but at least he wasn't much worse than that. His prolific basestealing was largely a thing of the past. The Red Sox, in their typical pre-2004 way, had found the way to make the most of Aparicio's weaknesses by batting him second and occasionally first. The 1971-73 Red Sox were a good team, winning 85, 89, and 84 games, with the 1972 unit finishing just a half-game behind the division-winning Tigers in a season infamously shortened by labor strife (another race we covered in It Ain't Over). Having Aparacio playing at a replacement level clearly didn't help; not only were his offensive and defensive contributions pushing the Sox in the wrong direction, but the club finished last in the league in defensive efficiency (eighth in park-adjusted defensive efficiency, or PADE, but still in negative territory). Aparacio was also a hindrance in 1973, when the team finished second, eight games behind the Orioles, despite solid pitching; receiving no offensive contribution from second base, third base, and shortstop didn't help. Seen in this light, Boston's promotion of Rick Burleson to starting shortstop, which came midway through the 1974 season, should be placed alongside the elevation of Jim Rice and Fred Lynn as key moments on the road to the 1975 pennant.

Similarly, the 1994 Cardinals, Ozzie Smith's last stand as a regular, finished last in PADE, albeit for reasons beyond Smith's declining powers. After a transitional year in 1995, the Cardinals won the NL Central with a re-aligned defense that included Royce Clayton as the regular shortstop.

Group Four: Which Lacks a Fourth 40-Year-Old
               Year Team       PA   G    AVG/ OBP/ SLG FRAA2 WARP3   W-L  Postseason?
Honus Wagner   1914 Pirates   616  150  .252/.317/.317   18   4.6   69-85   N

Luke Appling   1947 White Sox 572  139  .306/.386/.412  -12   4.2   70-84   N

Just three teams have employed a 40-year-old shortstop, and only one in more than 60 years: those veteran-lovin' Giants of 2007. Appling was still a force at the plate if not in the field, while Wagner had the reverse problem.

Group Five: Honus, 41, Alone
                Year Team     PA   G    AVG/ OBP/ SLG FRAA2 WARP3   W-L  Postseason?
Honus Wagner    1915 Pirates 625  156  .274/.325/.422   15   6.8   73-81   N

Even with his bat no longer the devastating weapon that it had been during his prime, Wagner was still good enough to play. It should be obvious at this point that there has been just one Wagner in baseball history, and for good reason: it's not necessarily that a man born 135 years ago was a greater physical specimen than the generations that have come after him, though this is possible. Rather more likely is that Wagner was an exceptional player, and an exceptionally slow-aging one, who towered over the league to an extent impossible now because the league of his time simply wasn't that good. In the present day, Wagner might still be worth playing in his 40s, but the distance between him and the league on both offense and defense would surely have eroded.

Luke Appling takes a year off from the list because the White Sox had him spend most of 1948 hanging out at third base. He'll rejoin us momentarily.

Group Six: The 42-Year-Olds (And There Are No 43-Year-Olds)
                Year Team        PA   G    AVG/ OBP/ SLG FRAA2 WARP3   W-L  Postseason?
Luke Appling    1949 White Sox  619  142  .301/.439/.394    1   4.4   63-91   N
Honus Wagner    1916 Pirates    484  123  .287/.350/.370    4   4.2   65-89   N

Both Appling and Wagner played another season, the latter spending most of his time at first base, the former going to the bench in favor of Chico Carrasquel, who was 20 years younger.

Although this list contains just two post-season teams, there is nothing conclusive about that aspect of the study; many of these teams had more problems than would have been solved by replacing the shortstop with a younger, more agile man, and in the case of some teams, such as the 1946 White Sox, such a move would have robbed the team of its best player. Still, the attrition on the list suggests the problem with re-signing Jeter. In the modern history of baseball, just a handful of players have been able to handle shortstop defensively at an advanced age. These were primarily players who were among the best defenders of their day in their prime. When they lost a step or two, they still had something to give. Not even Jeter's most ardent supporters place him in this category. Perhaps worse, even when the players were deemed capable of playing shortstop the attrition rate is high, dropping by a fifth in one year and by more than half in two years. As such, any multi-year contract is going to be a risk to the signing team.

The Jeter dilemma really is a juicy one, involving a popular player, a winning player in both senses of the word, who will be chasing the 3,000-hit mark in 2011. It's difficult to let go of a star, of course, but a team's first duty is to win, something which inevitably caters to a larger subset of its fans than belong to the cult of any one player. After 2010, the Yankees may be better served settling for a less spectacular player than their idealized memory of Jeter in his prime, a player who likely neither exists now nor will have returned three seasons hence. As this list shows, the rewards of staying too long at the ball with one's shortstop are both fleeting and few.

Yeah, if Appling played today he would probably be my favorite player. His 1948 stat line says it all. 594 PA 16 doubles 2 triples 0 home runs .314 AVG .423 OBP .354 SLG What a stud
How is it true that Aparacio "play[ed] at a replacement level" as a 39 yr. old when his WARP3 was 1.9? Isn't 2 wins above replacement level player a large enough adavantage not to consider a player to be performing at a replacement level?
I was thinkning the same thing. However, I wonder if Goldman is using the old replacement level floor for older players in terms of numbers? Under the revised level instituted this year, it would make Aparacio's playing replacement level when compared to today's players.
I realize SS is the more important position, but how would an aging Craig Biggio's sad final seasons at 2B stack up there, I wonder?
I don't know if 23-year-old Ramiro Pena is the answer to the Pastadiving Jeter question, but I DO hope the Yankee braintrust doesn't drink the "Jeter must get his 3,000th hit in a Yankee uni" Kool-Aid.
Isn't a better solution to resign Jeter and assign him to a utility role where he's still getting 400AB a year filling in all over the place? Hitting like he'll be hitting at that point in his career is more than acceptable for your supersub. the Yankees have the guts to force Jeter to do his best Tony Phillips impression so they can still get the 3,000th hit in a Yankees uniform?
If Jeter would accept that scenario, I'd be all for it. There are two possible problems: 1) Jeter's ego; and 2) Possible fan/media fury at the decision, particularly if the new starting SS isn't CLEARLY superior to old Captain Jetes. And by that I mean the new SS probably has to out-hit him as well as out-field him. Of course, by 2011, that shouldn't be very hard.
The biggest challenge in dumping Jeter would be finding a replacement. Basically, you need to be bringing in a big enough name that the fans might actually believe you've got someone better. At this point, the best hope (assuming the Phils exercise Jimmy Rollins' $8.5M option for 2011) is that the Mets don't find a way to extend Jose Reyes before he hits the market. Talk about a huge payday for Reyes of the Yanks want to get involved! The Mets certainly wouldn't want to lose their star SS to the cross-town Yankees, but the Yankees would have virtually no one else to chose from (at least no one with Jeter's star power). And imagine if the Yankees were to lose that bidding war! Now you're talking about dumping Jeter and THEN getting stiffed by the only guy who could really replace him. Quite a delicate situation for the Yankees. :-)
With Jeter being 35 this year, did you take this any further back in your study? At what age do we see shortstops helping teams to championships?
I'd like to see Price449's idea as well. Also, what about the average / median age of the players around him? Maybe teams with old SS also have a field full of old players which is more symptomatic of a management decision rather than solely the SS? Also, what is the WARP3 of the SS of two teams who made the World Series? I don't feel like the data presented here is a complete picture. That said, I don't honestly care where Jeter plays.
I did a quick check myself a week or two ago when this topic was first being discussed in the papers, and I believe Larry Bowa, 1980 Phillies, is the last regular shortstop who was 34 or older for a championsip team. (Bowa didn't turn 35 until December, 1980.) Jeter is 34 and turns 35 on June 26th. To get one older than Jeter, I think you have to go back to Pee Wee Reese, 1955, when he was 36 (he turned 37 on 7/23/55).
I'm not a Yankee fan, but I am a fan of schadenfreude, and seeing Yankee fans all worked up about something (five-year contract for Jeter) that is a) inevitable, and b) still two seasons away-- delicious.
It's worth noting that Maranville was a full-time player for two years after he stopped being a full-time shortstop. At ages 40 and 41 he played 149 and 142 games at 2B, handling 5.44 and 5.41 chances per game (in 513 career games at second, he handled 5.47 chances per game, so that isn't all that far off his career average. As a 39-year-old SS, he had an essentially league-average range factor (5.13 TC/G compared to 5.06 TC/G); as a 40+ second-baseman, he was also about league average (5.87 TC/G and 5.25 TC/G; league averages of 5.44 and 5.41). Which is pretty remarkable. Of course, he never could hit.
I still can't believe they played Jeter ahead of Rollins in the WBC semifinals against Japan.
I still can't believe the Yankees have been playing Jeter at shortstop over Alex Rodriguez all these years. Very nice article, Steven.
I agree with following it backwards. I think the decision to move ARod off shortstop for Jeter was questionable at the time, and the idea that Jeter is still the shortstop now is a liability for the Yankees (and certainly was one for the US in the WBC).
If the yankees were crazy enough to give old man posada a 4 year deal, i cringe at how they'll handle jeter
Just as a heads up, the pinstriped link at the beginning of the article goes to what looks like a squatter site.
