Herz struck out a dozen Dayton hitters over five innings in his start Wednesday for High-A South Bend, allowing no runs on a hit and a hit by pitch. He now has a 1.45 ERA, 0.86 WHIP and 53:17 K:BB across 37.1 innings.
Herz has been nearly impossible to hit in the minors going back to last season, as he allowed a composite batting average of .157 last year and has been even better with a microscopic .120 average against him this year. The main caveat for the 21-year-old is that Wednesday marked the first time in 10 starts this season that he's finished five innings, so he's never had to go through a lineup three times. His 4.1 BB/9 is a bit concerning as well. All in all, while Herz still has the potential to become a big-league starter, there's a strong probability that he ends up in a relief role -- but that's not necessarily a bad thing, as he could be a shutdown lefty out of the pen.
