Pitching against the Rockies at Coors Field, Lincecum gave up six runs on eight hits, lasting just 2 1/3 innings. He wasn't hit with the loss, which might be surprising considering that he already has 11 of them this year.
To go along with his 5-11 record, Lincecum owns a 5.62 ERA, the worst among National League qualifiers.
Lincecum will pitch again at Coors Field on Sunday in the finale of a three-game series, likely opposing the Rockies' Tyler Chatwood, who would be filling in for an injured Christian Friedrich. The Giants won the first two games by a combined score of 27-10.
In his last outing, Lincecum earned a win at home against the Mets. He scattered six hits over seven innings, allowing just one run. He struck out seven batters and walked one. It marked the sixth time this season that the two-time Cy Young Award winner held an opposing team to one run or fewer.
In 11 career starts at Coors Field, Lincecum is 4-3 with a 4.31 ERA. He's been taken deep six times and issued 68 strikeouts compared with 32 unintentional walks. He kept the ball in the park on April 11, but that's not what he was focused on afterward.
"A lot of pitches thrown in 2 1/3 and just sloppy baseball for me," Lincecum said at the time, not knowing just how difficult this season would be for him. "Just not really executing pitches and missing a lot. That's going to hurt you, especially here in this park."
Freidrich described the results of an MRI he underwent Friday evening as season-ending. He was originally supposed to start Thursday, but the outing was postponed because of back soreness.
"Stress fracture, lower back, right side, done for the year," said Friedrich, who is 5-8 with a 6.17 ERA.
"He went out to throw a bullpen yesterday, and the bullpen did not go well," manager Jim Tracy said before Saturday's game with the Giants. "I didn't hear that term [season-ending] mentioned to me. The way it was presented to me this afternoon by [head athletic trainer Keith Duggers] is that there is no timetable at this juncture. My understanding is he's going to seek another opinon. We'll have more information at that time."
Friedrich's expected Sunday replacement, Chatwood, was scratched from his start for Double-A Tulsa on Saturday night. Chatwood was 0-2 with a 5.79 ERA in nine Triple-A starts this year and 1-1 with a 3.00 ERA in four starts for Tulsa. He also went 1-1 with a 7.62 ERA in seven relief appearances with Colorado earlier this season.
Giants: Sandoval gets some light work in
Pablo Sandoval tested his strained left hamstring Saturday by taking batting practice and engaging in agility drills, bringing San Francisco closer to determining whether the third baseman will be ready for reinstatement from the disabled list when he becomes eligible Thursday.
"I think we're getting a better idea," manager Bruce Bochy said, though he wasn't certain if Sandoval will need to rehab his injury with a stint in the Minors.
Sandoval is batting .299 with eight home runs and 33 RBIs. He hasn't played since July 24.
The Giants announced the signing of outfielder Xavier Nady to a Triple-A Fresno contract Saturday. Nady, 33, has been hampered by right wrist tendinitis this season. He hit .157 with three home runs and six RBIs in 40 games before Washington designated him for assignment in late June.
Rockies: Cuddyer also hits disabled list
Right fielder Michael Cuddyer joined Friedrich on the disabled list with a strained right oblique. He sustained the injury Tuesday. Cuddyer is hitting .260 with 15 home runs and 56 RBIs.
"He's not any worse than he was a couple days ago when I reported that he was feeling discomfort in his right side," Tracy said. "He took batting practices yesterday. He took some swings both in the cage and on the field. He wasn't able to let it go like he wanted to, and so rather than push this, we just felt that it was the smartest thing to do to go ahead and back off now and get him the extra days so we can get him back out on the field."
Added Cuddyer: "I'll be ready when the 15 days are up."
In his big league debut, rookie utility man Matt McBride went 2-for-4 with a double, driving in a run and scoring one himself. He also had two strikeouts.
The Giants are 5-2 against the Rockies this season. After Sunday, the two teams play nine more times this year.
