SAN FRANCISCO -- Jonathan Sanchez threw on flat ground from 90 feet before Monday's game against the Padres and hasn't suffered any setbacks in his rehab, but that doesn't necessarily mean the lefty will slide back into the rotation after the All-Star break.

Giants manager Bruce Bochy said Sanchez, placed on the 15-day disabled list June 25 with bicep tendinitis, was feeling fine and is on track to throw a bullpen session in a few days. Bochy hasn't decided on his rotation following the Midsummer Classic, however, and didn't commit one way or the other when asked if Sanchez would be a part of it.

"I'll have to wait and really see how he's doing. That's a possibility, but it could take a little bit longer than that," Bochy said. "At this point, I have to rely on our training staff, our medical people and how Johnny's doing."

Ross feels OK after leaving with hamstring strain

SAN FRANCISCO -- Giants left fielder Cody Ross exited Monday's 5-3 loss to the Padres in the sixth inning due to a mild left hamstring strain and will undergo an MRI on Tuesday.

Ross said after the game he was "just a little sore," adding that he was taken out of the game for precautionary reasons and is having the MRI only to make sure "everything's intact and nothing crazy's going on." Ross wasn't sure whether he would be able to play Tuesday.

He came up limping in the top of the sixth after running down Kyle Phillips' flyout, saying he first felt the pain about halfway to the ball.

"Initially I thought it was not good, but I was able to jog and finish the inning and jog off the field," Ross said. "Those are positive signs. If it's something serious, I probably wouldn't even be able to walk, so I'm optimistic."

He told Giants manager Bruce Bochy he felt good enough to hit, but he would have to take it easy running to first base. Fortunately, Ross was able to take his time after drawing a walk. Right-hander Ryan Vogelsong then entered the game to pinch-run for Ross, while Andres Torres came in to play center field and Aaron Rowand moved from center to left.

Ross said the team doctor told him it was his hamstring, though he said the pain was more specifically in the back of his knee. They will continue to treat the injury with ice and anti-inflammatories, and Ross said he felt good enough to do everything but break into a full sprint.

Fontenot, Belt rehabbing at Triple-A

SAN FRANCISCO -- Mike Fontenot and Brandon Belt will continue their rehab assignments with Triple-A Fresno. Fontenot, who went hitless in his first three games for the Grizzlies before finally recording a hit Sunday, could even return to the Majors as soon as this weekend.

Bochy said he knew it would take awhile for Fontenot, out since May 25 with a groin strain, to shake the rust off and find his swing. The utility man will play seven innings in each of his next two outings, hoping to get three or four at-bats in each game.

"Is there a possibility this weekend? Yeah," Bochy said. "He feels good. That's what's important. He just needs at-bats.

Belt, meanwhile, moved his rehab assignment from Class A San Jose to Fresno on Monday. The left-handed slugger, working his way back from a hairline fracture in his left wrist, went 3-for-6 with a walk and a strikeout in two games for the San Jose Giants.

As is the case with Fontenot, Bochy said he will need to see how Belt is feeling and playing before making a final decision about his return to the Majors.

Worth noting

• Left-hander Barry Zito is donating $500 for every strikeout in Monday's game to Strikeouts for Troops, an organization founded by Zito in 2005 that provides support and comfort to wounded United States soliders and their families. Right-hander Tim Lincecum, starting Monday's game for the Giants, is second on the team with 9.77 strikeouts per nine innings -- behind only Sergio Romo's 13.15 K's per nine. Over his last three games entering Monday, Lincecum has averaged 9.33 strikeouts per game.

• With a first-inning double Monday, third baseman Pablo Sandoval extended his career-high hitting streak that began June 19 to 15 games. Counting Monday's first at-bat, during his hitting streak, Sandoval is hitting .306 (19-for-62) with eight doubles, two home runs and seven RBIs.

Sandoval has had at least one extra-base hit in each of his last nine games, tying the longest such streak in the Majors this season (Paul Konerko also had nine straight from May 30-June 10) and is now the longest for the Giants in the last 48 seasons. According to the Elias Sports Bureau, the only Giants with an eight-game streak of that kind in that span are Jack Clark in 1978 and Barry Bonds in 2004.

• According to STATS Inc., the Giants rank second to last in the Majors in scoring with a runner on third and less than two outs. They have scored 72 runs in 146 of those opportunities, and that .493 percentage is better than only the Cubs' .486 (68 scored in 140 opportunities).

• Entering Monday's game, the Giants had scored six runs or fewer in each of their 37 home contests this season. According to Elias, that is the second-longest single-season streak of home games in which the Giants have gone without scoring at least seven runs -- the New York Giants once owned a 38-game streak in 1902.
