DETROIT(AP) -- Carlos Pena and the Tampa Bay Rays headed into
September on a high note.

Next up, a key series against the Boston Red Sox.

Pena hit his AL-best 38th homer and drove in four runs to help
the Rays beat the Detroit Tigers 11-7 on Monday for a split of
their four-game series.

Tampa Bay scored six times in the first inning against the AL
Central leaders, capped by Pena's two-run drive. James Shields
remained unbeaten against Detroit, and Jason Bartlett added a
solo homer as the Rays moved within five games of idle Boston in
the wild-card race.

Tampa Bay hosts the Red Sox on Tuesday night, the start of a
three-game set.

"I don't know if it gets any bigger," Evan Longoria said. "Today
is a great way to head home. It should be fun."

Tampa Bay is 4-1 against the Red Sox at Tropicana Field this
season and has won seven of the first 11 meetings.

Carlos Guillen had four hits for Detroit, including a pair of
two-run homers.

Tigers starter Jarrod Washburn (9-8) allowed his first six
batters to reach base. The last was Pena, who hit a shot down
the right-field line. Pat Burrell had a two-run double earlier
in the inning.

"It was great," said Pena, who finished August with 12 homers
and had his seventh game this season with four or more RBIs.
"That first inning really put momentum on our side."

Pena added an RBI double in the fifth and Bartlett homered in
the sixth off Washburn, who lost for the second time since
joining the Tigers in a July 31 trade with Seattle. He left the
mound to a chorus of boos after allowing eight runs and nine
hits in 5 2-3 innings.

"He certainly didn't have very good success today," Detroit
manager Jim Leyland said. "Some of it by his own doing and some
of it was that's just the way it is sometimes.

"Sometimes it just isn't your day."

Pena singled in the first of three Tampa Bay runs off reliever
Ryan Perry in the seventh and finished a seven-game road trip
with four homers and 12 RBIs.

"Carlos is looking extremely sharp," Rays manager Joe Maddon
said.

Shields (9-10) allowed both two-run homers by Guillen, one in
the first and another in the seventh, but had little trouble in
between. The right-hander yielded four earned runs in seven
innings and struck out six to win his second consecutive outing
and improve to 3-0 in five career starts against the Tigers.

Guillen had his sixth career multihomer game. Detroit got its
last two runs in the ninth off reliever Brian Shouse.

"It feels good," Guillen said. "I hit the ball good. I was just
trying to stay short and make good contact."

NOTES: Pena missed his own club record for homers in a month by
one. He hit 13 in September 2007. The Rays' 43 August homers set
a club mark. ... Longoria scored three times. ... Guillen also
had his eighth career four-hit game. ... Tigers RHP Jeremy
Bonderman (shoulder) will be activated from an injury rehab

Ramirez and SS Brent Dlugach from Triple-A Toledo. ... Tampa Bay
RHP Andy Sonnanstine will be recalled Tuesday from Triple-A
Durham to start against Boston. The Rays also will call up C
