The 2015 season represented something of a banner year for position players pitching. That viewpoint assumes, of course, that you, as a baseball fan and reader of this website, consider position players pitching to be a good thing. For me, there’s also the sense, when a left fielder or second baseman — or any position player — takes the mound, that the game has reverted to a time and place when baseball was actually just a game. For some, that state might be viewed as an affront to those players who are seriously trying to win a spot in the big leagues. For others, it’s a time when the sport can shed its heavy cloak of seriousness and indulge in a rare bit of goofy self-deprecation. While I tend to align with the latter viewpoint, I respect and understand the former.
What can’t be argued is the increase in position players pitching over the past couple of years. With Cliff Pennington taking the mound in Game 4 of the ALCS last season, baseball logged its very first instance of a position player pitching in the playoffs, and it actually looked pretty good. In terms of raw appearances, 2015 was something of an apex for the non-pitcher pitching phenomenon. Jeff noted in June that 2015 was projected to equal 2014’s single-season record for the number of non-pitcher appearances on the mound; at the end of the season, 2015 had actually smashed the record (20 in 2014 vs. 27 in 2015).
What we’re after today, however, is how those non-pitcher pitching appearances actually went: what were the highlights? The lowlights? Who seems like he actually might be able to pitch? It behooves us, with the appearance of a new and fabulously interesting trend in major league baseball, to undertake a thorough review of said trend’s 2015 installment, with all the grace and seriousness we might give to potentially far more important subjects. What follows below is an attempt to do just that.
To begin with, let’s look at the overall stat line for the year in non-pitchers pitching compared to all of the “real” starters and relievers in 2015:
