Tim Lincecum has been streaky, but he has the opportunity to win his fourth straight when the Giants host the D-backs on Friday night.
The San Francisco right-hander has shaved nearly a run off his ERA while allowing one earned run in 23 1/3 innings spanning his last three starts. If Lincecum can win, he'd equal his highest victory total by the All-Star break since he was 9-4 in 2010.
"I have the confidence to use any of my pitches right now in any situation. That's what's been helping me," Lincecum said. "I'm just trying to throw the best pitch I can in any situation. ... If it's a ground ball, it's a ground ball. If it's a hit, I move on. And if it's a strikeout, I move on as well."
The Giants lost to the A's on Thursday as they dropped three of four in the Bay Bridge Series for a second straight year. On Friday they will go up against Arizona righty Mike Bolsinger, who's looking for his second career big league win. Bolsinger's only win came back on April 24 against the Cubs. He's yet to win since being recalled from Triple-A Reno on June 17.
Bolsinger got run support in his most recent start that he lacked in his previous two, but he gave up five earned runs against the Braves. He has pitched at least six innings in three of his past five starts.
Following his last outing, Bolsinger said he made some crucial and costly mistakes.
"[It] was probably the worst that I've had commanding," Bolsinger said. "Everything I was throwing was kind of up. I really didn't have a feel for my curveball, and I couldn't throw the inside fastball to righties. That was a big difference maker."
D-backs: Trumbo returns
Mark Trumbo was activated from the DL Friday.
Trumbo has been out since April 22 with a stress fracture in his right foot. He has been tearing up Triple-A pitching this week in his rehab assignment at Reno, hitting .458 (11-for-24) with five homers and 12 RBIs in seven games. He went 3-for-4 with a homer, RBI and two runs scored Tuesday night against Las Vegas, playing the full nine innings for the first time.
Giants: Scutaro making progress
Mired in a month-long slump, the Giants could use a boost. It sounds like Marco Scutaro is getting closer to potentially providing one. Scutaro (lower back strain) went 1-for-3 with an RBI in five innings Monday night in his first game at Triple-A Fresno.
The reports manager Bruce Bochy has received regarding Scutaro's progress are all positive. The 38-year-old is moving around well at second base, is comfortable diving for balls and hasn't been limited in the batter's box.
"He feels good. I think he's excited where he's at, so that's good news," Bochy said before Tuesday night's game. "We're seeing the light at the end of the tunnel with him."
Bochy said hope exists that Scutaro could play more than a few games per week upon returning, as was the original plan, but the manager stressed the team won't have a better idea of that until Scutaro plays a full nine-inning game and plays back-to-back games. Scutaro played six innings Tuesday, going 0-for-4 and scoring a run, then took Wednesday off. He was slated to serve as the Grizzlies' DH on Thursday night.
• The Giants are 31-4 when scoring five or more runs this season and 19-38 when scoring fewer than five.
• Paul Goldschmidt's 34 doubles prior to the All-Star break, a D-backs club record, are tied for the second most in the NL in the first half since 2005, trailing only Joey Votto's 35 in 2012.
