The Brewers fail to put their best foot forward.

Maybe, just maybe, this will turn out to be a significant moment in the history of baseball roster construction:

Considering all the pros and cons of a revolutionary way to structure a roster.

Baseball games come with built-in subtitles. Dwight Gooden vs. Roger Clemens in the 1986 World Series. Bob Gibson vs. Denny McClain in the 1968 World Series. Kyle Lohse vs. Ross Detwiler in Game 4 of the NLDS last year. It's one thing to see a game between the Yankees and Tigers, but it's an entirely different game if CC Sabathia is pitching against Justin Verlander. And no one ever subtitles the game A-Rod vs. Miguel Cabrera.

Overthinking It: Ranking Rivera

48

Ben Lindbergh

Can the best reliever ever hold a candle to history's strongest starters?

Recently, Mariano Rivera revealed that 2013 would be his final season. It wasn’t unexpected news, in that Rivera is 43 years old and coming off a serious injury that caused him to consider retirement in 2012. But the report, however predictable, hit many fans hard. Not only is Rivera respected and beloved both inside and outside of New York (a relative rarity for a big, bad Yankee), but he’s shown so little erosion in his skills that it’s possible to picture him throwing his cutter until he turns 50. Most players go through a decline phase, which gives us time to get used to the idea that it’s about to be over. Rivera really hasn’t, except in the sense that he’s less durable than he once was.

Rivera’s announcement inspired many written responses, one of which was an email to me from a reader named David Greene. “Rivera’s true ranking among pitchers all-time,” the subject line said.

Providing every team's bullpen picture at a glance.

Bullpen management: it’s one of the areas in which a major-league manager can make the most difference, and it’s also one of the areas in which we’re least likely to be satisfied with his work. But before we can pass judgment on a manager’s use of his bullpen, we have to know how he used it, and not just on an anecdotal level (although we agree that he made a mistake that one time your team lost a tie game on the road without using its rested ace reliever). On our Manager Pitching report, you can see how many relievers each manager used, and how many of those relief outings ended without a run being allowed. But that report won’t tell you who those relievers were, or when they were used.

That’s where BP’s new Bullpen Mis(management) Tool comes in. The BPM, which was inspired by this article, is the latest cool toy produced by Dan Brooks, the mind behind Brooks Baseball who also brought us the PITCHf/x Pitcher and Hitter Profiles, the PITCHfx Matchups Tool, and the PITCHf/x Leaderboards. It allows us to see the average Leverage Index when entering the game for all members of each team’s bullpen, both for a full season and over time.

A Little Relief

3

Jonah Birenbaum

Rafael Soriano is off the market, but there are still some potentially useful bullpen arms to be had.

Earlier this week, Jon Heyman tweeted a short list of free agent relievers who could be a reasonable fit for the back end of the Blue Jays’ bullpen. Whether you credit Heyman with clairvoyance or good contacts, it just so happened that one of the names conspicuously absent from that list was Rafael Soriano. Hours later, the 33-year-old right-hander became a member of the Washington Nationals, signing a two-year, $28-million deal with a vesting option for 2015.

In snapping up Soriano, the Nats removed the best available free agent reliever from the market, but they left an assortment of lower-tier options for teams still looking to bolster their bullpens. Ken Rosenthal later listed several teams still interested in picking up a reliever, identifying the Rays, Tigers, Mariners, Marlins, and Mets as potential suitors. Here are some of the options they can consider:

Baseball Therapy: In Praise of the Modern Bullpen

13

Russell A. Carleton

Sure, there might be better ways to construct bullpens than the way teams do it now, but change might not be as easy as you think.

The construction of the modern bullpen is silly. It starts with a junk stat (the save) and works backwards from there. There’s an anointed “closer,” his deputy (“the set-up guy”) who pitches the eighth inning, a couple of “match-up” relievers for the seventh inning, and some middle and long-relief guys who suck up innings four through six, as needed. In a close game, the relievers on the team with a lead are generally deployed in the (perceived) reverse order of their effectiveness as the innings unfold, with the apparent aim being to slowly choke off the other team’s chances of winning as the game goes further along. And to record a save.

Ben Lindbergh

The Yankees pull off another exciting comeback behind Raul Ibanez, only to lose both Game One and Derek Jeter a few innings later.

A few innings after Raul Ibanez solidified his True Yankee™ status with yet another ninth-inning, game-tying home run, seemingly setting the stage for an inevitable extra-innings win, the Yankees lost Game One. They also lost a leader and a pretty good player, leaving them looking much more vulnerable than they did a day ago. Here are three things to think about before Game Two gets underway.

Overthinking It: Baltimore's Best Bet to Beat Texas

7

Ben Lindbergh

If the Orioles want to extend their surprise season beyond the wild-card game, they should make the most of what got them there.

An Orioles fan might put money on the O’s to win their wild-card play-in game against Texas tomorrow night, but a betting man wouldn’t, at least with even odds. Then again, by now the betting man may have already gone broke backing Baltimore’s opponents.

The Orioles have spent the whole season surprising people. First they flouted the expectation that they couldn’t compete in the AL East, then the near-certainty that they couldn’t sustain their early-season success (or, for that matter, their success later on in the season). To reach the Division Series, they’ll have to have one more surprise in store.

Pebble Hunting: A Closer Look at Relievers and Leverage

3

Sam Miller

Which relievers were added to or removed from the managerial circle of trust between April and September?

On April 29, Bud Black summoned Dale Thayer from the bullpen to pitch the bottom of the eighth inning against the Giants. The Padres trailed by three runs and were already 98 percent likely to lose. It was, for Thayer and the Padres and the Giants and Bud Black, a very low-leverage situation. Just three times in his big-league career had Thayer pitched in even an average leverage situation. Every other time, it has been something more like mop-up work. Thayer threw a bunch of strikes and had a perfect inning.

Now skip ahead to September, and here are the situations in which Thayer has been called on:

If the Nationals had handled their ace's innings limit a little more like the Braves massaged Kris Medlen's, they might not be facing a Strasless October.

WARNING: Here there be hindsight.

We can’t say Mike Rizzo didn’t warn us. “There’s not going to be a whole lot of tinkering done,” he said. “We’re going to run him out there until his innings are done.” That was on February 20th, the earliest reference by Rizzo I can find to any specific plan for limiting Stephen Strasburg’s workload. We knew then that the Nats weren’t going to get creative: they were going to pitch Strasburg like any other starter until he was fresh out of innings. What we didn’t know then (and what we still don’t really know now), is when that would be. For months, everyone assumed Strasburg would go into storage after 160 innings. Why 160? As far as I can tell, the 160 meme began innocently enough, with this sentence from an mlb.com article by Bill Ladson on February 19th: “He is expected to throw 160 innings, the same number his teammate Jordan Zimmermann threw last year after coming off elbow reconstruction.” Expected by whom? The article didn’t say. Certainly not by the Nationals. But before long, 160 was ubiquitous, and usually attributed to the team. By the time Rizzo denied the number had come from him in an article at BP in April, it was already accepted as fact.
