While David Carpenter didn’t quite pan out, it looked like the Yankees acquired a gem in rookie southpaw Chasen Shreve.
For a majority of the 2015 season, Chasen Shreve was one of the best shutdown relievers in the american league, posting a 1.86 ERA and holding opposing hitters to a .177 batting average into the first week of September.
However, in what became one of the biggest mysteries of the season, Chasen Shreve did a complete 180 and turned into the equivalent of a batting practice pitcher down the stretch. Over his final nine appearances, the 25-year old southpaw served up 22 hits to the 36 batters he faced, including four home runs.
