Wittgren has surpassed his strikeout totals from last season, posting 43 in 42.1 innings so far this season.
In all of 2016, Wittgren only struck out 42 in 51.2 innings. With the improved strikeout numbers, however, has come an increase in walks as well. He is at 13 free passes in 2017, up from the 10 he had last year in his rookie season.
