ST. PETERSBURG, Fla.(AP) -- The Boston Red Sox didn't take any
chances.

With a seemingly comfortable lead slipping away in the eighth
inning Tuesday night, manager Terry Francona asked Jonathan
Papelbon to work overtime to finish off an 8-4 victory over the
Tampa Bay Rays.

"The way the inning was unfolding, it looked like the game was
going to be won or lost in the eighth," Francona said after his
closer bailed the AL wild-card leaders out of a jam and then
pitched a perfect ninth for his 33rd save.

"He got out of it with no runs, which is kind of hard to do. He
felt good enough to go back out and have a crisp ninth. So, it
worked out about as well as it could."

Papelbon entered with two runs in and the bases loaded with no
outs and shut down the AL champions with help from a diving
catch by center fielder Jacoby Ellsbury, who snared Jason
Bartlett's sinking liner before scrambling to his feet to keep a
runner from tagging up at third.

"That," Rays manager Joe Maddon said, "is a do-or-die play."

Papelbon, who struck out B.J. Upton for the first out, got Carl
Crawford to foul out to end the inning. The save was his fifth
of more than one inning.

"Those are pressure situations. The guy that's the coolest will
come out on top," Papelbon said. "You get into situations like
that, it boils down to focus. It's a focus thing."

The victory was the 11th in 14 games for Boston, which got a
rare win at Tropicana Field to drop Tampa Bay a season-high six
games behind the wild-card leaders.

Just as discouraging for the Rays, who also trail Texas in the
wild-card standings, was the announced crowd of 17,692 - less
than half the capacity at Tropicana Field and 11,755 less than
the teams averaged for six previous meetings in the domed
stadium this season.

The Red Sox, who lost to the Rays in a seven-game AL
championship series last year, remained 6 1/2 games behind the
first-place New York Yankees in the AL East.

The Rays vowed to battle back.

"I'm not frustrated at all," Maddon said, adding that he could
not fault his team's effort.

"They beat us. We made some mistakes. It happens," he said.
"What's that game time - 7:08 tomorrow night? We'll show up. I
promise you."

Jon Lester (11-7) allowed two runs and seven hits, walked one
and struck out nine in six innings. He gave up an RBI single and
solo homer to Carlos Pena, who hit his AL-leading 39th leading
off the fourth.

Francona said Lester left with tightness in his groin, but the
manager didn't think it was serious.

Bay hit his 30th homer, a solo shot in the fourth off Andy
Sonnanstine (6-8), who returned from a two-month stint in the
minor leagues to - at least for the moment - fill the opening in
Tampa Bay's rotation created by the trade that sent Scott Kazmir
to the Los Angeles Angels.

Drew hit a two-run homer off the Rays starter in the fourth.
Youkilis had a sacrifice fly off Sonnanstine and hit his 23rd
homer off Dan Wheeler to increase Boston's lead to 7-2 in the
eighth.

Billy Wagner pitched a perfect seventh in his second appearance
for the Red Sox since being acquired from the New York Mets last
week, but the Rays made it interesting in the eighth against
Hideki Okajima.

All five batters Okajima faced reached base, with Pat Burrell
and Dioner Navarro delivering RBI singles to trim Tampa Bay's
deficit to 7-4. Francona then turned to Papelbon an inning
earlier than usual.

Boston won for just the second time in seven games at Tropicana
Field this year. The Red Sox are 3-13 in the Rays' ballpark over
the past two regular seasons.

Sonnanstine made his first big league start since beating
Philadelphia on June 25. He had the highest ERA (6.61) in the
majors when he was demoted to the minors two days later, and was
1-7 with an 8.22 ERA in nine road starts.

The right-hander had been much sharper at home (5-0, 4.54 ERA)
before Tuesday night, although a pair of fielding errors - one
by second baseman Akinori Iwamura, and the other by first
baseman Pena - set up a pair of Boston runs.

"It's a tough game. Errors are going to happen," Sonnanstine
said. "I need to do a little bit better job of stopping the
floodgates from opening."

NOTES: Ellsbury's RBI triple in the ninth made it 8-4. ...
Lester struck out the side in the second, hiking his season
total to 191 - a record for a Red Sox left-hander. He finished
with 196. Bruce Hurst fanned 190 for Boston in 1987. ... Bay
reached 30 homers for the fourth time. ... Pena has four homers
in 26 career at-bats against Lester.
