Lincecum, the Giants right-hander, got the best of the Rockies and young Chatwood on Sunday in Denver in both pitchers' last starts. Now, the scene shifts to San Francisco for Friday's game, where Lincecum will be looking to keep his recent momentum going.
On Sunday, Lincecum won consecutive decisions for the first time since late April. He gave up one run on five hits in six innings and survived five walks, two of which came in the first inning, when he threw 36 pitches.
"I'll be honest -- that's a big first inning," Giants manager Bruce Bochy said. "I didn't know how much we were going to get out of him. He saved us by regrouping. That was impressive."
In three starts against Colorado this season, Lincecum is 1-0 with a 3.66 ERA.
As for Chatwood, the right-hander made his first big league start of the season Sunday and didn't last long, giving up three runs (one earned) on two hits while issuing four walks and striking out one in 3 1/3 innings.
What does Chatwood need?
"Consistency," Rockies manager Jim Tracy said. "Just like the same type of consistency we're looking for from some of our younger guys. Taking 80-84 pitches to get through four innings, there's obviously a road block somewhere down the line in the course of those innings that prevents them from going out there and pitching another.
"You can see from what he was doing that his stuff is more than good enough to get people out, but it's got to be in the zone on a regular basis. His misses have to be more competitive."
Rockies: Fowler racking up extra bases
Outfielder Dexter Fowler has 11 triples this year and 50 for his career, which makes him the Rockies' franchise leader. He leads the Major Leagues with his 11 triples, and 35 of his 96 hits are for extra bases.
Giants: Buster still busting out
Since the All-Star break, catcher Buster Posey has hit safely in 22 of 24 games, batting .446 (41-for-92) with 13 runs scored, seven doubles, eight home runs, 30 RBIs and 13 walks. Since the break, he's led the Majors in batting average, RBIs, on-base percentage and slugging percentage. He also has hit five home runs and has driven in 12 over his last eight games.
Bochy is pleased with his team's performance on its just-completed road trip, on which it went 5-2.
"The boys have done well, haven't they?" he said. "That's the hope: You build momentum on the road and carry it home. If you get on a rut, whether it's at home or on the road, you hope a change of scenery can get guys going again. We had a rough homestand and we're thinking, 'Hey, let's get on the road and see if we can find it.' The guys have done a great job on this road trip."
Rockies outfielder Eric Young Jr. has 14 hits and eight runs over his last six starts since July 31.
Entering Thursday, the Giants' 22 one-run victories were the second-most in the Majors behind Pittsburgh (23).
Left-handed batters are 7-for-their-last-43 (.163) against Giants reliever Javier Lopez and 13-for-62 (.210) overall. Lopez leads the club with 50 appearances this season.
