What It Means:

Mengden opened the season at Double-A and made four starts at that level, posting a 0.78 ERA in that space. After he was leveled up to Triple-A, the results weren't much different. In seven starts at that level, the 23-year-old right-hander held a 1.39 ERA, 0.84 WHIP and 39/10 K/BB ratio over 45 1/3 innings. There is no guarantee that he can replicate that fine work at the major league level, but if he can stick in the rotation -- Jesse Hahn was just sent to Triple-A -- he makes for a decent speculative add in deeper AL-only formats.

This season has arguably been Mengden's best as a professional, posting a 2.18 FIP in Double-A and a 3.74 FIP in Triple-A, to go with strikeout percentages of 30.1 and 22.4 respectively. The Reds have a team wOBA of just .308 -- which ranks 22nd -- so they make for a potentially nice matchup for a Major League debut.
