For Quantrill, it was his sixth consecutive outing allowing less than three runs, this time allowing just two over five-and-a-third innings. He struck out four and allowed only three hits, the most damaging of which came via a Tommy Pham two-run blast in the first inning.
Offensively, the Padres tallied 10 hits as a team, including two from both Eric Hosmer and Francisco Mejía. One of the Hosmer knocks came in the form of a solo homer, matching his 2018 season total of 18.
It was yet another strong offensive night for Luis Urías, who filled in at shortstop for the injured Fernando Tatis Jr. He doubled, walked and was hit by a pitch on the day, driving in three to bring his five-day RBI total to eight.
Matt Strahm, Luis Perdomo, Andres Muñoz and Kirby Yates all enjoyed scoreless outings in relief of Quantrill.
The Friars will be off on Thursday before opening a three-game set in Philadelphia against Bryce Harper and the Phillies on Friday night.
