DETROIT (AP) -- The Detroit Tigers won the same way -- just with a different star in the ninth inning.
It was the fourth win in a row for the Tigers, who finished a three-game sweep and won on a game-ending homer for the second consecutive game. Eric Munson homered in the ninth Saturday night.
"Back-to-back wins have been tough enough to come by around here, let alone back-to-back walk-off home runs," Bobby Higginson said.
Rondell White hit a two-run shot for Detroit, which tied it at 5 in the seventh on back-to-back doubles by Higginson and Carlos
"Nothing's going our way. When we don't pitch well, we hit, when we don't hit, sometimes we don't make the pitch," said Danny Bautista, who hit a three-run homer for the Diamondbacks. "Right
now, it's a little bit tough to put everything together."
Infante moved to third on Higginson's fly to right, and Guillen and Dmitri Young were walked intentionally to load the bases.
Koplove struck out White and took Peña to a 2-2 count before he sent the next pitch into the right-field bullpen for his second career slam.
"I wasn't trying to hit a home run, just trying to get a piece of it," Pena said.
While Pena thought he hit a fastball, it was actually a changeup. Koplove threw a changeup all seven pitches to Pena, batting just .233 this season.
"You throw seven in a row of anything to a hitter, eventually they're going to figure it out," Arizona manager Bob Brenly said.
Jamie Walker (1-2) got the win, setting down eight straight batters in 2 2-3 innings.
Tigers starter Mike Maroth allowed five runs and nine hits in five-plus innings.
Diamondbacks starter Steve Sparks gave up four runs and 11 hits in 5 1-3 innings. The knuckleballer struck out four and didn't walk a batter.
Detroit went ahead 2-0 in the second on RBI singles by Mike DiFelice and Infante, but Bautista's three-run homer in the third gave Arizona a 3-2 lead.
The Diamondbacks stretched their lead to 5-2 with two runs in the sixth as they chased Maroth. Bautista singled leading off the inning and went to third on Luis Gonzalez's double into the
right-field corner. Consecutive singles by Shea Hillenbrand and
Greg Colbrunn each scored a run.
Tim Olson followed with a single to load the bases, and Maroth was replaced by Danny Patterson. He prevented further damage by getting Juan Brito to tap into a catcher-to-first double play and
retiring Andy Green on a popup.
"He [Patterson], to me, was the difference in the ballgame,"
Detroit manager Alan Trammell said.
The Tigers made it 5-4 in the sixth on White's homer. It also
scored Young, who led off with a single.
Pena's other grand slam came on May 19, 2003, against
Cleveland. ... White's home run broke an 0-for-13 slump. ...
Arizona's Steve Finley has reached base five times in the last two
games (three hits and two walks). ... Guillen has five RBI in the
past two games. He hit the 100th double of his career. ... Gonzalez
got the 450th double of his career. ... Before the game, the Tigers
honored their 1984 team that won the World Series.
