While he doesn't sport the same finely-crafted beard of Danny Salazar, Cleveland Indians minor league pitcher J.P. Feyereisen has been doing his best Sal impression on the mound while striking out batters are an alarming rate. So far in his young minor league career, Feyereisen has pitched 28.0 innings in the closing role split between his time on the Mahoning Valley Scrappers in 2014 and the Lake County Captains this year. In those 28.0 innings he's struck out 42 batters, allowed 11 hits, and walked only 5. Oh, and he hasn't allowed a single run.
During his college career at Wisconsin, Feyereisen put up similarly impressive numbers. His 2.69 ERA, 59 strikeouts in 77 innings as a starter was enough to help the Wisconsin-Stevens Point Pointers make it to 2013 Division III World Series. His 94 mph fastball and plus slider attracted the Indians to take the 22-year-old in the 16th round of the 2014 draft.
In 2015 alone, Feyereisen has come into the game in 7 save opportunities (11 total games) and converted every single one, thanks to a 4-1 strike to walk ratio with 18 K's and 4 BB's. He has struck out at least one batter in every one of those 11 games, and he struck out 2 batters in 7 of them. His 14.73 K/9, 3.27 BB/9, and zero home runs allowed converts to a superb 1.17 FIP.
The only other pitcher at the Class A level to throw more innings and not allow a run this season has been St. Louis Cardinals prospect Kyle Grana. The 24-year-old RHP has thrown 11.2 innings without allowing a run for the Peoria Chiefs, but he's also given up 2 more walks than Feyereisen.
There's no reason to rush Feyereisen to the majors after one fantastic season's worth of work at the Class A level, but he'll be a great prospect to keep an eye on as he climbs the ladder.
