The single-admission doubleheader was scheduled after Sunday afternoon's game was postponed due to inclement weather. Game 1 is at 4:10 p.m. ET.
Mets right-hander Miguel Batista will start the first game for New York, which won the second game of the series on Saturday in dramatic walk-off fashion after blowing a ninth-inning lead. He'll be up against the sputtering Tim Lincecum, who is experiencing a discouraging three-game stretch unlike any other he's seen in his impressive young career.
Lincecum has allowed 16 runs in three starts this season, the most of any three-game stretch in his six-year career, and is 0-2 with a 10.54 ERA.
"I don't care how much time you've had in this game," Giants manager Bruce Bochy said of Lincecum's struggles. "You like success, whether it's Spring Training or two or three games of a small sample size. You don't like to not throw the ball well. Even veterans experience it. Good hitters go into slumps."
Batista, making his first start of the season, has a 5.40 ERA in six games (five innings). He is 5-8 with a 4.40 ERA in his career against San Francisco.
The second game of the twin bill will pit Madison Bumgarner against Dillon Gee.
Gee, who was slated to pitch against Lincecum on Sunday, is coming off one of the best starts of his career. He lasted seven innings, striking out five and scattering four hits and just one run against the Braves.
Mets manager Terry Collins credits not only his pitchers, but the catchers they're throwing to, with the success of the pitching staff at this point in the season.
"Our catchers have done a really good job of taking part and taking some ownership in the game planning, which I think has made a big difference," Collins said. "I think the pitchers are now understanding it, you don't see as many shakes in certain situations. I think, between innings, there is more conversation between the pitchers and the catchers, so that the next inning they got a little bit better idea of how they want to attack the hitters."
Gee, 1-1 with a 2.92 ERA this season, has never started against the Giants. Bumgarner has allowed just three earned runs over his last two outings combined (13 1/3 innings).
Mets: Hot at the top Center fielder Kirk Nieuwenhuis went 0-for-5 on Saturday, but he still has a hit in seven of his last eight games and is hitting .357 (10-for-28) during that span. He has also scored at least one run in four of the last five games (six runs total).
Saturday was the first game this season that Mets third baseman David Wright did not reach base safely at least twice (by way of hit, walk or hit by pitch). That was the longest such stretch to start a season in club history.
Wright's 10-game hitting streak to start the year was also snapped.
The Mets started the season 4-0 at home, but are 1-3 at Citi Field since.
Giants: Panda streaking to begin season San Francisco's Pablo Sandoval has hit safely in all 14 games this season, batting .333 (19-for-57) with two homers and 10 RBIs in that stretch.
His hit streak is the longest active streak in the National League.
Bochy said this weekend he hopes to see the Giants' defense improve in the coming days. The club has made 19 errors in 14 games.
"It's been up and down, particularly with the defense," Bochy said. "We're just making too many mistakes at this point and we're probably lucky to be where we're at -- not that we're anywhere -- considering the way we've kicked the ball around. I think we've hurt ourselves in three games that we probably beat ourselves. That's the way I look at it, and I still think it's going to get better."
Worth noting All fans holding tickets from Sunday's game who wish to attend Monday's doubleheader may exchange their tickets at the Citi Field ticket windows for admission. Fans may also exchange their tickets for those comparable in price and location to another Mets 2012 home game.
Sunday's game was scheduled to include a Tom Seaver bobblehead promotion, which has been rescheduled for May 5, when the Mets host the D-backs at 4:05 p.m. The Giants have won each of their last three series (at Colorado, vs. Pittsburgh, vs. Philadelphia) after being swept in the season-opening series at Arizona.
