Walker did not factor into the decision in Sunday's loss to the Nationals, allowing three earned runs on four hits and three walks in 4.2 innings. He struck out three.

Walker started strong, throwing three scoreless innings before allowing a two-run blast to Keibert Ruiz in the fourth inning. Walker surrendered another home run in the fifth -- a solo shot to Alex Call. Walker has been mediocre in two starts since returning from a finger injury, pitching to a 6.23 ERA, 1.62 WHIP and an ugly 8:6 K:BB in 8.2 innings. The 32-year-old will look to rebound in his next start, currently scheduled for next weekend in Kansas City.
