Holmes was struck by a comebacker Friday and fractured his right fibula, creating another hole on the big-league staff. Wenninger has been impressive of late for Triple-A Syracuse, tossing 16.2 scoreless innings over his last three starts while allowing only seven hits with a 19:7 K:BB, but his overall 38:18 K:BB in 33.1 frames this season suggests he could still use some more development time. The 24-year-old right-hander is next set to take the mound Sunday for Syracuse, while the Mets will need a new starting pitcher May 20 when Holmes' next turn would have come around, so whether Wenninger gets scratched this weekend will provide an early clue as to the organization's plans.

Christian Scott is already up in the majors to help out a beleaguered Mets rotation, and Wenninger is making a case to leapfrog Jonah Tong and be the next arm to get called up. Through his first five starts for Syracuse, Wenninger sports a 1.61 ERA, 1.27 WHIP and 26:12 K:BB over 22.1 innings -- a sharp contrast to Tong's 5.68 ERA and 1.39 WHIP in 25.1 innings, although he's also struck out 38 batters against 15 walks. Both young right-handers have control issues to iron out, but with Kodai Senga (back) on the IL and David Peterson struggling badly, there could be another spot open in the big-league rotation very soon.
