Quintana (5-4) allowed four earned runs on five hits and two walks while striking out six across 4.1 innings to take the loss Saturday against the Giants.
Quintana looked to be headed for his second consecutive strong outing but stumbled badly in the fourth and fifth innings. He first allowed a two-run homer to left-hander Brandon Crawford and then allowed back-to-back doubles prior to being lifted in the fifth inning. The outing continued his struggles at home this season, as three of his four starts in which he has surrendered four or more earned runs have come at home.
