Fluke: RHP Hayden Wesneski
Among the Cubs starters, Wesneski had the second-best ERA (2.12) in Spring Training behind only Marcus Stroman. In his five starts, Wesneski looked sharp, striking out 22 men in 17 innings. This work even won him the fifth starter role over Adrian Sampson and he looked like the next great young pitcher.
However, this success did not carry over to the regular season and it seems like Wesneski still has a lot to figure out. In 53 innings, the 25-year-old has an ugly ERA of 5.20 and a batting average against of .256. Perhaps most concerning is the 13 long balls Wesneski has surrendered, meaning when he misses his pitches he's missing them in the heart of the plate.
If he wants to remain in the starting conversation, or even the bullpen conversation for that matter, Wesneski will have to figure out what his issues are so he can start helping this team in a meaningful way. He has one of the best sliders in the game, making his ceiling very high and there is still time to get back on track with Kyle Hendricks back.
