The Rangers left fielder shows off his...knuckleball?

Rangers left fielder David Murphy is normally a solid offensive contributor, posting a career .277 TAv. This season, he’s been subpar at just .234. What’s a manager to do? Why not change his position? Ron Washington, short of arms in a 17–5 blowout at the hands of the Red Sox on Tuesday night, decided to audition Murphy as a relief pitcher.

Alex Sanabia may have broken a rule, but he probably didn't alter the outcome of a game.

As you may have heard by now, Marlins pitcher Alex Sanabia indisputably spat on a baseball last night directly after surrendering a home run to the Phillies’ Domonic Brown. David Brown of Big League Stew downplayed its ultimate effect on the game, but at least one Philly sportswriter took great umbrage at this infraction. (Bonus points to the commenter on that last link who said, “Maybe our team should try it? The bullpen in particular.”)

Examining the performance of the players who aren't supposed to pitch.

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.)

Pitcher Profile: Jordan Zimmermann and Contact


Dan Rozenson

Can Jordan Zimmermann keep getting batters to hit into outs?

Jordan Zimmermann, in a starting rotation with Stephen Strasburg and Gio Gonzalez, doesn’t get much attention. But did you know he led the Nationals pitching staff in quality starts last year? And that he leads the major leagues in WHIP this year? Zimmermann’s path to success, especially so far this year, defies basic sabermetric assumptions and is worth examining more closely.

Zimmermann is built like a power pitcher. He’s a sturdy 6’2”, 220 lbs., and he has a fastball that averages better than 94 mph. He has a hard slider and much-improved curveball as his secondary pitches, as well as an occasional changeup. He has the pure “stuff” to strike out 200 batters a season.

Why Jack Morris' accusation doesn't stand up to the evidence.

As you’ve probably heard, pitcher-turned-commentator Jack Morris has accused Red Sox hurler Clay Buchholz of throwing pitches with illegal substances on his hand during his start on Wednesday against Toronto. Buchholz, his manager, and his catchers have taken turns explaining that that’s a ridiculous proposition.

A PITCHf/x look at the type of arsenal that fares well at altitude.

Most of our writers didn't enter the world sporting an @baseballprospectus.com address; with a few exceptions, they started out somewhere else. In an effort to up your reading pleasure while tipping our caps to some of the most illuminating work being done elsewhere on the internet, we'll be yielding the stage once a week to the best and brightest baseball writers, researchers and thinkers from outside of the BP umbrella. If you'd like to nominate a guest contributor (including yourself), please drop us a line.
