Giants may soon tweak pitching rotation

San Francisco (59-77) at Colorado (64-74), Mon., 12:05 p.m. PT

CINCINNATI -- The Giants aren't changing their starting rotation for their upcoming three-game series against the Colorado Rockies in Denver. But manager Bruce Bochy won't make any promises about what might happen afterward.

Bochy said that he and his staff are discussing the possibility of altering the rotation for the season's final weeks. Whether the Giants add a starter after Monday, when rosters can be expanded to 40 players, obviously will be an integral factor. Although the Giants have plenty of pitching talent at the Class A level, nobody in the upper Minors stands out as a candidate for promotion -- with the possible exception of right-hander Matt Palmer, who started three games before being optioned back to Triple-A Fresno last Tuesday.

Bochy acknowledged that Thursday's scheduled off-day could ease the task of adjusting the rotation, since the pitching order can be changed without starters losing rest.

Asked if these changes are being considered to lighten the workloads of Tim Lincecum and Matt Cain, who are virtually assured of topping 200 innings apiece, Bochy said, "Right now, no."

But right-hander Kevin Correia complained of a tired arm after allowing six runs in six innings Saturday against the Reds and could be vulnerable to being skipped for a turn.

Pitching matchup
SF: LHP Jonathan Sanchez (8-9, 4.53 ERA)
This will be Sanchez's first start since leaving the disabled list. He missed three starts with a strained throwing shoulder and was replaced in the rotation by Palmer. Sanchez didn't look at all like he was hurting in his last performance, as he allowed two runs and five hits in seven innings Aug. 11 in a 3-1 loss at Houston. But before that, he was unable to work six innings in six consecutive starts. Sanchez has faced the Rockies three times this season, earning a win June 12 despite yielding seven runs in five innings.

COL: LHP Jorge De La Rosa (7-7, 5.60 ERA)
De La Rosa turned in a quality start in his last outing, also against the Giants. He gave up one earned run on five hits, walking three and striking out three. He's put together four consecutive quality starts and has won four of his last six decisions.

The Giants are 6-6 against Colorado this season. The balance has been maintained in the home/road breakdown, with the teams splitting the six games played in each park. ... When Sanchez faces the Rockies, expect him to be careful with Garrett Atkins, who's batting .385 (5-for-13) with three doubles against him. Jeff Baker, hitting .571 (4-for-7) off Sanchez, might find his way into Colorado's lineup. ... Rockies catcher Chris Iannetta has enjoyed otherworldly success against Lincecum, hitting .714 (5-for-7) with two doubles and a homer off the Giants ace. ... Including Sunday, the Giants are in a stretch of three afternoon games in four days.
