SAN FRANCISCO(AP) -- Bengie Molina gave the San Francisco Giants
something to think about as they contemplate whether to bring
the veteran catcher back for another year.

Molina, who is eligible for free agency this offseason, homered
twice and drove in four runs Tuesday night to lead the Giants to
an 8-4 victory over the Arizona Diamondbacks that kept San
Francisco's slim wild-card hopes alive.

"We don't know what's going to happen and Bengie doesn't know
what's going to happen," San Francisco manager Bruce Bochy said.
"I do know he's done a great job here. We wouldn't be in this
position ... without Bengie. He's going to be fine no matter
what happens."

Pablo Sandoval had four hits and two RBIs for the Giants, who
trail NL wild card-leading Colorado by five with five games
left. The Rockies beat Milwaukee 7-5 in 11 innings.

Playing in what could be his last home series with the Giants,
Molina had one of his best nights at the team's waterfront
stadium after sitting out the previous three games with bruised
fingers on his left hand. San Francisco's popular catcher
matched his season high with four RBIs and went deep twice for
the second time this year, giving him a career-high 20.

Molina, 35, hit a two-run homer off Doug Davis in the fourth and
followed Sandoval's two-run shot in the seventh with a drive off
Clay Zavada.

But the Giants need to add more offense and have 2008
first-round draft pick Buster Posey, who hit .325 with 18 homers
and 80 RBIs in the minors this year, waiting to take over behind
the plate.

"Hopefully he'll get back with us and help us like he has the
last three years," winning pitcher Jonathan Sanchez said. "The
way he handles the pitching is amazing."

Molina wasn't in the locker room when reporters were allowed in
after the game.

Miguel Montero homered twice, including a two-run drive into
McCovey Cove in the sixth, for Arizona.

"We gave them a lot of baserunners and allowed them to create
rallies," Diamondbacks manager A.J. Hinch said. "We couldn't get
out of anything. We always felt like we were one out away from
getting out of something but with two outs they never let up.
Sandoval and Molina were the difference in the game."

Sandoval had two singles, a double and his 23rd homer to raise
his average to .329. He also scored four times.

Sanchez (8-12) retired 11 of the first 13 batters he faced
before yielding Montero's two-run homer in the fourth. The next
batter, Ryan Roberts, hit what was initially ruled a homer
before umpires, using instant replay, changed it to a
ground-rule double.

Left fielder Andres Torres appeared to catch the ball after
leaping at the fence, but it popped out of his glove and landed
on top of the wall momentarily before dropping off. Torres, who
had fallen on his back on the warning track, reached up and
grabbed the ball out of the air but third base umpire Dana
DeMuth signaled home run.

Bochy came out to protest and the umpiring crew left the field
briefly to view the replay before returning and changing the
call to a double. Sanchez then retired Rusty Ryal to end the
inning.

Sanchez allowed three runs and five hits in 5 1-3 innings. Bob
Howry, Dan Runzler, Jeremy Affeldt and Sergio Romo combined to
finish the seven-hitter.

"We're still breathing," Bochy said. "There's a little hope, not
a lot."

Montero's towering drive in the sixth was the first ball hit
into McCovey Cove by a Giants opponent this season and cut San
Francisco's lead to 4-3. Montero picked up his first multihomer
game of the year and third of his career.

"It was like a home run derby," Montero said. "It was a long
game, it was miserable because it was too long and it looked
like the ball was flying today."

Sandoval doubled leading off the bottom half and scored on a
single by Molina.

Davis (8-14) beat San Francisco a week earlier when he went 7
1-3 innings but the left-hander wasn't nearly as sharp this
time. He gave up seven hits and walked five in four innings
while losing for the sixth time in his last eight starts.

Eugenio Velez scored on a wild pitch in the first and Aaron
Rowand drew a bases-loaded walk to give the Giants a 2-0 lead.

NOTES: The Diamondbacks fell to 2-8 at AT&T Park this season.
