MILWAUKEE (AP) -- Brandon Phillips hit a 450-foot grand slam that landed in Bernie Brewer's slide in deep left field and Travis Wood earned his first win in the majors for the Cincinnati Reds , 10-2 over Milwaukee on Wednesday.

The Reds scored 10 unanswered runs, capped by Phillips' shot and Joey Votto 's solo homer in the eighth.

With the win, Cincinnati kept the pressure on St. Louis for first in the NL Central after the teams entered play Wednesday in a virtual tie at the top.

Wood (1-1), who took a perfect game into the ninth inning on July 10, won in his sixth career start and the Reds piled on the runs, scoring five in the sixth off starter

Chris Narveson and reliever Kameron Loe and five more off Carlos Villanueva in the eighth.

Cincinnati finished the trip 4-2 and is 26-24 away from Great American Ball Park.

The Reds' bullpen of Jordan Smith , Arthur Rhodes , Nick Masset and Francisco Cordero combined for four scoreless innings, allowing three hits.

Trailing 2-0, the first six batters reached to start the sixth for the Reds, who sent 11 men to the plate. Votto's RBI single chased Narveson (8-7) and Jonny Gomes tied the game when he drove in the 300th run of his career with a double off Loe.

Miguel Cairo followed with a two-run double and Ryan Hanigan 's squeeze bunt made it 5-2. The long inning ended Wood's day, who finished scattering five hits and a walk with six strikeouts over five innings.

In the eighth, Villanueva loaded the bases on two singles and a walk to bring up Phillips, who hit the ball into the bright yellow slide in left field that starts in the upper deck and spirals down to the club level for his fourth career slam.

Votto followed two batters later with another shot to left field that made it 10-2. The slugging first baseman is 14 of 26 with three homers, nine runs and six RBIs in his last six games.

Cincinnati scored 22 runs off 32 hits in the final two games of this series after managing two runs off six hits in a 3-2 loss in the opener on Monday night.

Milwaukee had been playing better baseball of late, but the Brewers trail the Reds by nine games in the division with the non-waiver trade deadline looming Saturday.

Wood struck out five consecutive batters at one point, but trailed 2-0 on Ryan Braun 's RBI double and run-scoring single by Jonathan Lucroy . It could've been more, but right fielder Jay Bruce made a diving grab on a soft flare by Carlos Gomez to end the inning.
