Montgomery dropped to 2-2 in Tuesday's 8-7 loss to the Diamondbacks, allowing seven earned runs on 10 hits and no walks over four innings. He struck out two in the 79-pitch outing.
After three consecutive quality starts, the 30-year-old lefty turned in by far his worst outing of the season. Though he threw 52 of his 79 pitches for strikes, Montgomery was knocked around, with five of the 10 hits he allowed going for extra bases. The blowup start inflated his season ERA and WHIP to 4.84 and 1.34, respectively.
