Scuffling Giants facing sweep in Toronto

The Giants can't be loving their trip north of the border.

San Francisco, which hadn't played Toronto since 2007, has dropped the first two games to the Blue Jays, after apparently leaving its bats in the U.S.

The Giants wasted back-to-back superior outings from their starters on Friday and Saturday, scoring a total of two runs.

They'll try to do for Jonathan Sanchez on Sunday what they were unable to do for Barry Zito and Matt Cain and get the offense rolling to pick up a victory before they roll out of town. Standing in the Giants' way will be veteran Shaun Marcum, who, despite being somewhat inconsistent of late, has shown his toughness this season.

After being knocked around by the Rays in his previous start, Marcum settled down to pick up a win over the Padres on Monday. The Jays' right-hander held the Friars to two runs in seven innings. But he's still struggling with keeping balls in the park, allowing two homers in that contest alone.

It wasn't an easy win, as Marcum was in and out of trouble all night, especially when he wiggled off the hook in the seventh with just one run scoring after having the bases loaded and nobody out. Marcum retired the next three batters in order.

"We were fortunate there in the seventh to get out of that," Marcum said. "We ended up getting out of the jam. It was something that I needed to do, to get out of there with some damage control and try to get out of there with the lead."

Sanchez wasn't bouncing back from as big of a loss in his last outing, but he still rebounded from a shaky outing of his own, in which he only lasted five innings against the Reds. But he beat the Orioles in convincing fashion his last time out, allowing two runs in 7 2/3 innings.

"I was pretty comfortable out there. When you get a couple runs, you can just go out there and relax," Sanchez said. "I just went out there and followed [catcher Eli] Whiteside. Everything he called, I was throwing it, and that's how the game went."

Giants: Renteria returns
Edgar Renteria, back in the lineup on Saturday after missing a chunk of this season on the disabled list with a strained right hamstring, got one of the Giants' four hits on Saturday. His presence, manager Bruce Bochy said, is too key to not have in there, despite the recent success of Juan Uribe. On Saturday, Bochy did some lineup juggling and moved Uribe into the designated-hitter role. He's not worried about finding everyone enough playing time though, as the Giants will start a stretch of 19 games in 19 days on Tuesday.

"It will be a little easier because we can rotate, give some guys a day off," Bochy said. "Put Juan at third or second, Pablo [Sandoval] at first, get Edgar to move around."

Blue Jays: Lind returning to roots
Adam Lind, whom manager Cito Gaston says will now also handle backup-first-baseman duties, has been battling his way through a slump at the plate. He has seen his average drop to .204 entering play on Saturday, but Gaston has been patient, leaving Lind in the No. 3 hole. Lind showed signs of breaking out of it on Saturday, with a 2-for-4 day at the dish.

"It's like I try something new every day," said Lind, who hit .305 with 35 homers and 114 RBIs in 2009. "I think it was a mechanical [issue] and then trying to do things, I lost my aggressiveness, thinking about me at the plate instead of the ball.

Worth noting
The Giants announced that Tuesday's series-opening start against the Astros will go to Cy Young Award winner Tim Lincecum, who will go on five days' rest. This move means they will skip their fifth starter, left-hander Joe Martinez. ... Aaron Hill hit his 10th homer of the season on Saturday.
