Looking to help the visiting Giants avoid a fourth straight defeat, Peavy tries to win four straight starts for the first time in five years Tuesday night against the Arizona Diamondbacks.Peavy (5-4, 2.29 ERA) posted a 4.82 ERA and received six runs of support while on the mound in losing his first three starts after San Francisco (82-68) acquired him from Boston on July 26. However, in his last six outings, the right-hander is 5-1 with a 1.12 ERA and has received an average of 6.92 runs of support."It's been fun to watch him, to see the intensity and the talent that Jake has, and he's been on every start," manager Bruce Bochy told MLB's official website. "A couple starts our defense probably hurt him, but he's really commanding the ball well, all of his pitches."Peavy allowed his only earned run over 19 1/3 innings of his last three outings in a sixth inning he never finished during Thursday's 6-2 victory over Arizona (62-88).Peavy, who last won four in a row over his final four starts of 2009, sees some of the same qualities in the Giants that he experienced while winning his first World Series ring with Boston in 2013."We're showing up with a fresh attitude every day, and certainly a lot of the same spirit is in this (clubhouse)," Peavy said after dropping his ERA to 3.12 while winning his fourth consecutive start against the Diamondbacks.He hopes to help wild card-leading San Francisco end a three-game skid during which its starters have yielded 14 runs in 13 2/3 innings.The Giants also have scored four runs during that slide and could be in for another tough challenge against Josh Collmenter (10-7, 3.67), who allowed three hits over six innings in their 5-0 victory Thursday."He was good," Giants outfielder Gregor Blanco said about Collmenter, who has yielded two earned runs and 14 hits over 27 2/3 innings while going 2-0 in his last four starts."Good changeup. He was locating the fastball. He was tough to hit. He was keeping us out of balance."The right-hander has overcome six walks to allow one run in 11 innings while going 1-0 in two starts against the Giants this season.Buster Posey, though, is 3 for 6 this season, and 9 for 14 with two home runs and a double lifetime versus Collmenter.Posey is batting .408 with 12 RBIs in his last 13 games at Chase Field.San Francisco had won 16 of 21 at Arizona before Mark Trumbo's grand slam highlighted the Diamondbacks' season high-tying third straight victory, 6-2 on Monday.Trumbo is batting .239 during a disappointing season in which he missed almost three months with a broken foot, but is 6 for 12 with nine RBIs in the last three games."He's kind of hitting his stride lately, swinging the bat much better, more comfortable," Arizona manager Kirk Gibson said.Trumbo, however, is 1 for 8 with three strikeouts versus Peavy.
Josh Collmenter has allowed an opponent batting average of .143 over the past month in at-bats ending with a pitch down in the zone or below, the eighth-best mark in the NL among pitchers. Pablo Sandoval is hitting .172 over the past month in at-bats ending with a pitch down in the zone or below.
