Walker (8-7) struck out 10 over five shutout innings and allowed just three hits and three walks to earn the win Friday against the Rockies.
The only problem with racking up so many strikeouts in so few innings is you also rack up a huge pitch count, too. Walker threw 93 pitches in just five frames, and with bullpens bolstered by September call-ups, the Diamondbacks decided not to push him too hard. Walker has now reached double-digit strikeouts three times this season, and when he is on, few pitchers in the nation are harder to hit.
