"It's good he'll get another opportunity," A's manager Bob Melvin said of Overton. "Obviously the reason for it is not great, but this is a guy we talked about in Spring Training and we felt like at some point in time he'd get an opportunity, and this will be his second one."
Overton, who had not pitched above the Double-A level before this year, made two starts upon his first callup, delivering mixed results. He picked up the win in his debut with 5 2/3 innings of three-run ball against the Angels, before stumbling in a three-inning, eight-run outing against the Giants.
Overton returned to Triple-A Nashville and posted a 2.77 ERA in two starts, both wins. He'll be pitching on eight days' rest Tuesday, having thrown on the side three times in that span.
"The last game I was up here, we kind of switched some things up and obviously it didn't work out very well," Overton said. "I wasn't working in to as many hitters as much as I wanted to, so I wasn't able to open up the outside part of the plate with my changeup, and usually I like to throw way in to hitters and then use the changeup on the other side, so I just went back to that when I went down and everything's been good."
Melvin said there's still no timetable for Hill's next start. Triggs, he noted, is "going to do everything he can to not go on the disabled list."
