LOS ANGELES(AP) -- Andre Ethier still has a hard time believing
his uncanny ability to generate game-winning hits.

Ethier hit a two-run homer in the 13th inning - his major
league-leading sixth walkoff hit of the season - giving the Los
Angeles Dodgers a 5-4 victory over the Pittsburgh Pirates on
Tuesday night.

"You pinch yourself," he said. "If there's a heartbeat left, we
can come back and try to win it. I was just looking for a good
pitch to hit and put a good swing on something."

Four of Ethier's game-ending hits have been home runs, the
latest gave the Dodgers their 37th comeback win of the season
and earned him a curtain call. The NL West leaders moved five
games ahead of Colorado, which lost 10-2 at San Francisco, and
had their magic number to clinch a playoff berth reduced to 10.

"As Yogi would say, `It's deja vu all over again,"' Dodgers
manager Joe Torre said, quoting former New York Yankees catcher
Yogi Berra. "You've seen him do it, you want to visualize it,
and when he does it, it's just surreal."

Ethier sent the first pitch from Phil Dumatrait (0-1) into the
right field pavilion with one out for his 30th homer and 97th
and 98th RBIs of the season. Rafael Furcal opened the inning
with a line drive single that struck Chris Bootcheck on the
right leg and ricocheted between first and second base.

"I went with a two-seamer in, and I went and looked at the video
and it was just above the knees and a little bit off the plate,"
Dumatrait said. "I made my pitch and he just kind of dropped the
head of the bat on it and put a good swing on it, and
unfortunately it went out of the park. It's frustrating. He just
beat me on that one pitch."

The Pirates had taken a 4-3 lead in the top of the inning on
Ryan Doumit's RBI single. The go-ahead run was unearned because
of a throwing error by third baseman Casey Blake on Andrew
McCutchen's routine grounder. Andy LaRoche sacrificed McCutchen
to second before Garrett Jones was intentionally walked. Doumit
faced an 0-1 count from Ronald Belisario (4-3) before he singled
to left, scoring McCutchen.

"It was a great game," Pirates manager John Russell said. "We
thought we had it won twice. Unfortunately, they're a great team
and they've had a lot of comeback wins this year."

The Dodgers wasted a golden opportunity in the 12th after
pinch-hitter Juan Pierre tripled with one out off Steven
Jackson. The Pirates pulled the infield in and Orlando Hudson
grounded out to second before pinch-hitter James Loney grounded
out to first.

Los Angeles tied the game 3-3 in the ninth on Matt Kemp's RBI
single off Matt Capps, whose blown save was his fifth in 30
chances.

"If I get that last pitch down to Kemp, he swings over it and
it's a ground ball. But I missed up in the zone and you can't
afford to do that," Capps said. "We should have won that game in
the ninth. The guys played hard and busted their butts all night
to put us in that situation, and it didn't work out."

Ethier started the rally with a one-out double to right. Manny
Ramirez popped to first before Kemp lined his opposite field hit
to right on a 2-1 pitch. He took second on the throw home and
Blake reached on a walk before pinch-hitter Jim Thome grounded
to short to end the inning.

"They never quit," Torre said. "This has been a team effort all
year and we have 16 left. Hopefully it just stays this way all
the way to the end."

The Pirates scored three runs in the second. Steve Pearce hit
his fourth homer just over the wall in left, a two-run shot that
scored Lastings Milledge, who walked. Zach Duke's RBI single to
center with two outs scored Ronny Cedeno, who doubled.

The Dodgers got two runs back in the fifth on Blake's RBI triple
and Mark Loretta's sacrifice fly.

Duke allowed two runs and four hits in 7 1-3 innings, tied his
season high with seven strikeouts and walked none. The All-Star
left-hander had allowed a total of 13 runs in the first inning
of his last three starts, but he retired the first 10 batters to
start the game.

Los Angeles starter Randy Wolf gave up three runs and five hits
in seven innings, struck out five and walked two after missing
his start last Friday at San Francisco with a hyperextended left
elbow. Wolf said afterward that his arm is feeling good.
