Darvish recorded six strikeouts and allowed four runs on seven hits across 6.2 innings during a no-decision against the Pirates on Wednesday.
The 32-year-old didn't issue a free pass Wednesday, but he did yield two homers. Darvish has allowed nine home runs in his last five appearances, and he only avoided a loss Wednesday because the Cubs responded with a homer to take the lead after he departed. Darvish is 2-4 with a 5.01 ERA, 1.34 WHIP and 111 strikeouts in 97 innings this season.
