Giants’ streak at five, Susac heads to DL

PHOENIX — The Giants’ express continues to roll, but this time they hit a bump in the road along the way.

Jake Peavy got his first win of the season and Buster Posey drove in four runs in an 8-4 triumph over the Arizona Diamondbacks on Saturday night, as the Giants stretched their win streak to five in a row. They also clinched their 10th consecutive series victory over the Diamondbacks at Chase Field, their most on the road since 13 straight against the Boston Beaneaters/Doves from 1903 to 1907.

But the team will be without  catcher Andrew Susac after he sprained his right thumb on a head-first slide into third base in the fourth inning. X-rays were negative, but the reserve was placed on the disabled list. Hector Sanchez is expected to be recalled from Triple A Sacramento today.

“He’s going to get an MRI, and we’re going to (try to) rule that out,” manager Bruce Bochy said of the possibility of ligament damage. “We’ll do more diagnostics to find out is something is going on wrong there.”

Susac led off the inning with his second triple of the season and remained in the game long enough to score on Angel Pagan’s sacrifice fly. He was lifted after the inning and was replaced behind the plate by Buster Posey, leaving the Giants without a legitimate backup catcher.

After Posey caught all 12 innings in a 6-5 victory the previous day, he started at first base and drove in three with a pair of singles and a sacrifice fly.

“It was a long one last night,” Posey said. “I mean, any you time get five-hour games, you’re going to be on your feet a lot. Both teams spent a lot of time on defense standing on the field, so it was a good win to get today.”

Peavy (1-4), making his fifth start of the season and third after missing all of May and June with a back strain, allowed four runs and eight hits in 6 1/3 innings. He also had his first hit in a Giants’ uniform.

Sergio Romo pitched the final 1 1/3 innings for his first save of the season.

“Jake threw well,” Bochy said “He had good stuff, you know. He got us to the seventh, which I thought was important for our bullpen after we had a long game last night. He battled. He got a little tired at the end there, but it was a gutty effort, I thought. He got out of a couple of jams and made some good pitches.”

The Diamondbacks’ Chase Anderson (4-4) had his shortest outing of the season. In 3²⁄³ innings, he allowed seven runs on 10 hits, nine of them singles.

Matt Duffy had three hits, drove in two runs and scored twice for the Giants, who had 13 singles among their 14 hits. Brandon Crawford had a two-run single in a four-run third inning.

“Nice hitting at the top of the order,” Bochy said. “They did a good job using the whole field and going the other way. Pagan, (Joe) Panik, Duffy, Posey had 10 hits or so, the first four guys. That’s usually a good thing. You’re usually going to put up runs when that happens.”

David Peralta homered and hit his third triple in the last two nights for Arizona. Cliff Pennington, whose throwing error allowed the winning run to score Friday night, hit his first home run of the season and second career pinch-hit homer.

Pennington, the last batter Peavy faced, hit a solo home run to cut the lead to 7-4 in the seventh. Posey’s RBI single off Enrique Burgos boosted the lead to 8-4 in the eighth.

Bochy said a CT scan showed Nori Aoki’s fractured right fibula is 80 percent healed. He expects the outfielder to be able to begin baseball activity in about two weeks.

The Giants will send Madison Bumgarner (9-5, 3.33 ERA) to the mound against Patrick Corbin (1-1, 5.40) in the series finale today.
