CINCINNATI (Ticker) -- Brad Wilkerson continues to pester the Cincinnati Reds .

Wilkerson homered twice, including a go-ahead two-run shot in the seventh inning, to lift the Montreal Expos to a 4-2 triumph over the National League-leading Reds.

Wilkerson went 3-for-4 with three RBI and is batting .467 (7-for-15) with four home runs and five RBI against the Reds this season. Eight of his last nine hits have been for extra bases - five home runs and three doubles.

"It was like icing on the cake to have a game like there where I used to come and watch games," said Wilkerson, who grew up three hours away in Owensboro, Kentucky. "It feels good to get the win. Zach (Day) pitched great."

Day (4-6), a Cincinnati native pitching in front of his hometown crowd for the first time, allowed two runs and four hits in six innings to earn just his second win in seven starts.

"It's like a dream come true to pitch in your hometown," said Day, who had more than 100 friends and relatives cheering for him as he took the mound. "I had to focus and it was tough but not as hard as I thought it would be."

Day struggled early with control but settled in as the game wore on. The Expos have been shut out three times with him on the mound.

"We had good pitching, timely hitting by Wilky and good relief," said Expos manager Frank Robinson , who spent the first 10 years of his Hall of Fame career here. "Day started out a little rough but if he throws the ball over the plate, he's tough. I'd like to see him get his pitch count down so he can go deeper in the game, but I'll take what he gave us. You always like to win in front of family and friends. I'm glad he got the win. He deserved it."

Luis Ayala pitched a scoreless seventh and Chad Cordero a perfect eighth before Rocky Biddle worked out of trouble in the ninth for his 11th save in 13 opportunities. With runners on first and third, Biddle struck out pinch hitter Barry Larkin looking to end the contest.

"We just didn't get a whole lot of offense," Reds manager Dave Miley said. "They threw the ball well, and we just didn't get the big hit."

The game was tied, 2-2, before Terrmel Sledge led off the seventh with a bunt single against Reds starter Jose Acevedo (3-4). Two outs later, Wilkerson sent a 3-2 offering over the wall in right field for his ninth homer of the season.

"It was a fastball, 3-2," Acevedo said. "He just got me. The pitch came back over the plate."

The Reds opened the scoring in the second, when Ken Griffey Jr. drew a leadoff walk and Adam Dunn followed with his 15th homer. Each of Dunn's last four hits have been home runs.

"I was more upset about the walk," Day said. "I made my pitch (to Dunn) up and in, where I wanted. You have to tip your hat to him."

The Expos halved the deficit in the fourth, when Jose Vidro led off with a double and scored on a sacrifice fly by Orlando Cabrera . Wilkerson tied it with a leadoff homer in the fifth.
