Now he'll face them in a place where he has excelled.The Colorado Rockies starter has pitched well at AT&T Park heading into Monday night's matchup with Tim Lincecum to start a three-game set.Chacin (13-8, 3.16 ERA) battled through a high fever to throw 6 2/3 hitless innings before Brandon Crawford singled in a 5-4 victory for Colorado (66-78) on Aug. 28. It marked the longest bid for a no-hitter ever at Coors Field."We couldn't figure him out," Giants manager Bruce Bochy said after that game. "He mixed it up, we chased some pitches and just couldn't get anything going against him."The right-hander is 2-1 in four starts at AT&T Park with a 1.44 ERA -- his lowest mark in any visiting stadium in which he has started more than twice.Chacin's previous outing against the Giants extended his streak to 10 starts in a row in which he yielded three runs or fewer. That was snapped Tuesday when he allowed four over seven innings to suffer a 7-4 defeat to the Dodgers.Crawford is a .318 hitter against Chacin, Pablo Sandoval is at .292 and Buster Posey is 7 for 16.Lincecum (9-13, 4.50) has posted a 4.24 ERA in winning three straight starts for the first time in three seasons. He wasn't happy after he gave up five runs in 5 2/3 innings Wednesday in a 13-5 win at San Diego."I didn't attack it the way I wanted to," Lincecum said. "When you have the answers to the test and you don't put them down, it is a little frustrating."The right-hander is 0-2 with an 8.00 ERA in three starts against the Rockies this year. Michael Cuddyer is one of three Colorado hitters to take Lincecum deep and is 6 for 14 against him overall.DJ LeMahieu figures to be back in the Rockies lineup after he was rested in Sunday's 5-2 loss at San Diego. LeMahieu is 16 for 41 (.390) during a career-high 10-game hitting streak.He could help spark Colorado, which totaled six runs and hit .177 while being swept in three games over the weekend by the Padres.Catcher Wilin Rosario missed the last two games due to problems with his wisdom teeth, and his status for Monday is unclear.These teams have split 16 meetings, and the last-place Giants (64-79) enter this series after splitting four home games with Arizona. Angel Pagan delivered the winning RBI single in the 11th inning of Sunday's 3-2 victory.Posey has two hits in his return after missing four games with a fracture in his swollen right ring finger. He's hitting .420 with four homers and 11 RBIs against the Rockies this year.Teammate Hunter Pence needs a home run to become the first Giants player to record at least 20 home runs and 20 steals in a season since Barry Bonds in 1998.Colorado's Dexter Fowler is hitting a team-high .385 in the season series, but has missed the last two games with a knee injury.
