Tim Lincecum's 11 career wins against the Rockies are his second-most against any one team. Lifetime against Colorado, Lincecum has struck out 177 batters in 176 2/3 innings. In his only start against the Rockies this season, Lincecum limited Colorado to three hits and two runs over six innings.
Those are just some of the many reasons why the Rockies are surely satisfied in manager Bruce Bochy's decision to replace Lincecum with Yusmeiro Petit in the starting rotation.
Of course, Lincecum hasn't been particularly sharp of late, serving up 26 earned runs in his last 24 2/3 innings pitched. But in 39 career innings against the Rockies, Petit has surrendered 43 hits, 21 earned runs and 16 walks.
Don't tell that to the new and improved Petit, though.
Petit has retired 38 consecutive batters over his last seven appearances (six relief, one start). That's just seven batters shy of tying Mark Buerhle's Major League record set from July 18-28 back in 2009.
So what's his secret?
"I just try to throw strikes and get ahead on the count every time possible," Petit said. "I'm always ready and prepared for anything that can happen."
Colorado will be countering Petit with right-hander Jordan Lyles.
Since he returned from a broken non-pitching hand, the Rockies have won three of Lyles' four starts, although he only has one personal victory to show for it.
Most recently against the Marlins on Saturday, Lyles wasn't looking sharp. In his 5 2/3-inning no-decision, he ended up walking five while allowing seven hits and three earned runs.
In two career starts against the Giants, Lyles is 1-0 with a 2.70 ERA. Thursday will mark his first career start in San Francisco.
Rockies: Rosario, Logan land on 15-day disabled list
The Rockies placed catcher Wilin Rosario and left-hander Boone Logan on the 15-day disabled list Wednesday.
Rosario had missed the past four games with a sore left wrist and apparently the injury wasn't progressing as the team hoped.
As for Logan, this is the third time he has landed on the DL with left elbow inflammation this season and fourth time he's been on the shelf overall. Logan had surgery on his pitching elbow this past offseason, but the Rockies don't currently anticipate him requiring another.
To take their roster spots, the Rockies recalled catcher Jackson Williams and left-hander Christian Friedrich from Triple-A Colorado Springs.
Giants: 'Very slim' Sanchez returns in 2014
Giants catcher Hector Sanchez is unlikely to return this season as he continues to battle post-concussion symptoms.
Sanchez has already been shut down from all base-related activates for at least the next three weeks after visiting a concussion specialist Tuesday. On Wednesday, manager Bruce Bochy categorized the chances the Giants see him on the field again this year as "very slim." "There's nothing he can do about it," Bochy said of Sanchez, who suffered his second concussion this season earlier this month. "He just needs more rest."
Lately, Sanchez has felt nauseous and dizzy while performing even the lightest of exercises.
In 66 games with the Giants, the switch-hitter is batting .196 with three home runs and 28 RBIs.
• Left-hander Jorge De La Rosa (thumb) will make his next scheduled start, according to Rockies manager Walt Weiss. De La Rosa was forced from Tuesday's start early with the injury.
• Giants catcher Buster Posey hit his third home run in the last two days Wednesday to give San Francisco a 4-2 walk-off victory over the Rockies. It was his second career walk-off homer.
