CINCINNATI -- Felipe Lopez has matched Ken Griffey Jr. in homers -- for part of a season, anyway.
Surprising? Not to Lopez, who did more in one night than Griffey and two of his 500-homer partners combined.
Before the first pitch, three of the game's greatest power hitters posed behind home plate for a commemorative photograph. The interleague series marked the first time that three 500-homer sluggers played together -- Sammy Sosa (580), Rafael Palmeiro (559) and Griffey (511).
As in the series opener, the trio watched a lightweight do the damage. Lopez, who has 32 homers in five seasons, hit his grand slam in the second inning off Daniel Cabrera (5-5). Lopez and Griffey are now tied for second on the Reds with 10 homers apiece.
"I'm not surprised at the power," said the shortstop, who had never hit more than eight in a season. "I've always been capable of hitting home runs. That's not my game, but I can hit them. I try to stay patient and not miss too many pitches. That's what I did when I was young -- missed too many pitches."
Given a big early lead, Brandon Claussen (3-3) held the AL's top hitting lineup to three hits over a career-high eight innings. The left-hander lost his shutout when Sal Fasano homered with two outs in the eighth.
"Any pitcher will tell you -- or even hitters -- that once you get in a groove, it's easy," Claussen said. "The key is to stay in it."
Adam Dunn added a two-run shot for the Reds, who have homered 15 times in the last five games against Tampa Bay and Baltimore. Lopez's two-run single gave him a career-high six RBI.
The game started with a touch of nostalgia. Pitcher Jose Rijo and center fielder Eric Davis -- the cornerstones of Cincinnati's 1990 World Series championship team -- were inducted into the team's Hall of Fame.
Lopez got the crowd of 32,834 to its feet again with his decisive homer in the second inning, when the Reds loaded the bases with none out on a pair of singles and a walk. Cabrera then walked Claussen -- 0-for-13 this season -- on four pitches, forcing in a run. Three pitches later, Lopez homered to right off a fastball.
"He got me in the first inning on a similar pitch," Lopez said. "I tried to stay back and hit the ball hard somewhere. The ball stayed up, and I took advantage."
It was a breakthrough for the Reds, who were hitting .192 with the bases loaded and less than two outs. During a 4-3 loss to the Orioles on Friday, the Reds loaded the bases twice and managed only one run -- on a wild pitch.
It also marked the second time in the series that a low-profile hitter delivered the game's pivotal homer. Baltimore's Melvin Mora had a three-run shot on Friday night, putting the Orioles ahead to stay.
Dunn added his 16th homer off another fastball as Cincinnati knocked Cabrera out of the game in the third. The right-hander matched his season high by giving up seven runs in two-plus innings, his shortest start of the season.
Manager Lee Mazzilli talked to Cabrera on the mound before deciding to take him out.
"I asked him what the problem was," Mazzilli said. "He really didn't know. He just didn't feel right, he said. "As soon as he said he didn't feel right, that was it."
Cabrera has been maddeningly inconsistent this season, failing to go four innings in three of his 12 starts. His problem Saturday was an unpredictable fastball.
"My ball was moving too much," he said. "I tried to control that."
The 500-homer trio got only one ball as far as the warning track -- Griffey's fly out in the first inning. They've combined for one extra-base hit in the series, Griffey's solo homer on Friday night.
Sosa is 0-for-6 with four strikeouts in the series, played in the ballpark where he hit No. 500 two years ago with the Cubs. Since returning May 24 from an infected left foot, Sosa is hitting .186 with two homers.
Lopez's other grand slam was April 26 in Chicago off Ryan Dempster. Lopez is 3-for-4 with the bases loaded this season. ... OF Wily Mo Pena and 2B Ryan Freel were out of the Reds lineup with sore knees. ... Eli Marrero, acquired by the Orioles in a trade with Kansas City on Wednesday, made his first start for Baltimore -- in center field. ... Right-handed batters are hitting .188 off Cabrera without a homer. Left-handers are .313 with seven homers. ... The Orioles are 6-6 on a 13-game, four-city trip that is their longest of the season. ... Griffey's 13-game hitting streak ended. ... Baltimore's Steve Reed made his 825th appearance, moving ahead of Tug McGraw for 27th place on the career list.
