Darvish (7-3) allowed three runs on three hits and three walks while striking out four over 5.1 innings to earn the win over the Diamondbacks on Friday.
Darvish allowed 10 runs over 25.1 innings in September after returning from a lengthy absence due to elbow inflammation, but he won three of his five starts in that span. The right-hander concludes the regular season with a 3.31 ERA, 1.07 WHIP and 78:22 K:BB over 81.2 innings across 16 starts.
