While the first half of the season was mostly stellar, the second half has been a different story. After the Mets clinched first place, Walker struggled with a 7.13 ERA in 13 starts. His strikeout rate dropped from nine to seven and he allowed 20 home runs in 64.1 innings. However, his velocity remained consistent throughout the season. This is a positive for Walker’s future, as his ERA should improve with time.
