Scouting Alberto Gonzalez and Other Position-Player Pitchers
At some point, you’ve probably thought to yourself that you could do a better job than the man on the mound for your team, especially if your team has ever employed Jonathan Sanchez. And every so often, amateurs do get the chance to outshine actual pitchers. These brave volunteers are known as “position players,” and they’re occasionally called in to provide a desperate manager with outs so that a blowout game may mercifully end. Surprisingly, these rescue arms are not off-the-charts terrible, with position players who’ve debuted since the 2000 season posting a combined 6.84 ERA (6.76 FIP) in 51 1/3 innings—and that drops to a 5.11 ERA (6.34 FIP) if you exclude Paul Janish’s two rough innings.
The Yankees were in dire straits on Wednesday night after the unpredictable Phil Hughes lasted only 2/3 of an inning, surrendering seven runs on six hits and two walks. This forced manager Joe Girardi to get 5 2/3 innings of long relief from Brett Marshall in his major-league debut. After Marshall’s pitch count reached 108 pitches with two outs in the ninth, Girardi asked Alberto Gonzalez, a journeyman infielder with no prior professional pitching experience, to get Robert Andino out. Somehow, he did. (Granted, Andino, who owns a .236 OBP, is among the easiest outs in baseball. But still.)
Let’s see how Gonzalez’s performance matches up with recent position-player pitching appearances, using some common observations about these kinds of occasions. (I used the pitch data of all position-player appearances in the PITCHf/x era.)
Position players work quickly on the mound
Gonzalez set a very rapid pace in his outing, averaging 10.8 seconds between pitches. That’s the third-fastest pace on record, as a matter of fact. That up-tempo approach keeps hitters on their toes and defenses alert.
Gonzalez Mound presence Grade: A+
Pitch speeds tend to sit between the upper 70s and the mid-80s
Gonzalez’s pitch speed fell into a pretty typical range, averaging 81 mph. Whereas some position-player pitchers add and subtract speed seemingly at random, Gonzalez’s velo showed little variation. Gonzalez’s fastball also had a good 10 inches of rise and a little bit of tailing action.
Gonzalez Fastball Grade: B-
A lot of fill-ins have off-speed pitches
Gonzalez Secondary pitches Grade: F
Position players throw high in (and above) the zone
For the sake of comparison, here are Gonzalez’s pitch locations as displayed by Brooks Baseball.
Gonzalez also threw pretty high in the zone, and his first couple of pitches missed the target wildly. That invites a lot of deep counts and hard-hit balls.
Gonzalez Command Grade: D
Mechanical problems abound—but they do in regular pitchers, too
Gonzalez works out of a simple stretch, raises his leg gingerly, cocks his arm soundly, and then lunges forward with his delivery, rather than letting his arm drag behind his body, as some pitchers today do. He ends the delivery in good fielding position. Still, it looks like he could benefit from better leg drive.
Gonzalez Mechanics Grade: B
Overall, Gonzalez acquitted himself pretty well as a substitute pitcher. His career ERA is a cool 0.00 for now, but he’ll need to consider adding an off-speed pitch if he really wants to join the elite corps of emergency arms.
