SAN FRANCISCO -- The Giants selected the contract of left-hander Andrew Suarez from Triple-A Sacramento prior to Suarez's first career start in San Francisco's 7-3 loss to Arizona in Wednesday afternoon's series finale.
In corresponding roster moves, Madison Bumgarner was transferred to the 60-day disabled list and reliever Steven Okert was optioned back to Sacramento after one day with the Giants.
Bumgarner's move to the 60-day disabled list means that the earliest he would be eligible to be activated would be May 25. The lefty continues to recover from a fractured finger in his pitching hand sustained during Spring Training.
Suarez, the Giants' No. 10 prospect according to MLB Pipeline, retired the first 10 hitters he faced on Wednesday and attacked the strike zone effectively, allowing only four hits and striking out seven without issuing a walk. However, he fell victim to the long ball, as he allowed homers to Paul Goldschmidt and John Ryan Murphy on a pair of hanging sliders.

The 25-year-old left-hander was ultimately charged with four earned runs in 5 1/3 innings pitched. He was lifted after 83 pitches.
"I thought he did a nice job," manager Bruce Bochy said. "Sure, he made a couple of mistakes, but I thought overall, it was a pretty good job by him in his first start, his debut. Again, throwing strikes. He worked ahead, and I know there are a couple of pitches, sure, that he'd like to have back, but I thought it was pretty impressive."
The Giants have already guaranteed a second start on Sunday to right-hander Tyler Beede, who debuted Tuesday, but despite Suarez's promising outing, Bochy hesitated to offer a similarly concrete timeline for Suarez's next start.
"He'll get another chance. I can't tell you when," Bochy said. "We'll wait and see. We're talking about it now. He's going to pitch up here, I can tell you that, at some point, whether he's making another start here real soon, depending on Johnny [Cueto]'s ankle, but we'll wait."
On Wednesday, Suarez took the rotation spot of Johnny Cueto, who was placed on the 10-day disabled list on Tuesday following a left ankle sprain suffered during a workout.
Despite the uncertainty in his timeline, Suarez remained unconcerned.
"I'm just going through it day by day, and whatever happens, happens," Suarez said.
