Adams, who was reinstated from the 15-day disabled list Saturday, threw all six of his pitches en route to getting three outs for the Missions.
"I got plenty of sweat down there," Adams joked, noting the game was played near his home in Corpus Christi. "I got a little extra work in the bullpen."
Adams landed on the disabled list after suffering a strained left oblique in the last game before the All-Star break in Colorado on July 11.
In the corresponding roster move Saturday, reliever Ryan Webb was optioned to Triple-A Portland. Webb was 3-1 with a 3.05 ERA with San Diego. He'll be back after the rosters expand from 25 to 40 on Sept. 1
"He'll be back," Padres manager Bud Black said. "There's some things he needs to clean up."
Despite missing nearly a month, Adams said he feels like he's fortunate to get back to the active roster as soon as he did.
"Actually, I think it went a lot faster ... I originally thought it was four-to-six or a six-to-eight week injury. I'm happy it took under a month."
Adams said it wasn't until a week ago and after three bullpen sessions before he didn't feel any pain from the strain. He missed 19 games.
Adams, the Padres' eighth-inning specialist, is 2-1 with a 2.18 ERA in 42 games this season. He thinks the break, while not ideal, could benefit him moving forward.
"I missed probably 10 to 12 outings -- that could be big come October," Adams said.
