Pence doubles in ninth, Astros beat Reds 4-3

Hunter Pence hit a tiebreaking double in the ninth inning and the Houston Astros avoided a series sweep with a 4-3 win over the Cincinnati Reds on Wednesday.

Mike Leake (3-2) walked J.R. Towles with one out in the ninth before Pence's full-count hit landed in the corner of right field and sent Towles home.

The Astros led 3-1 before the Reds tied it with consecutive homers by Chris Heisey and Drew Stubbs in the seventh inning.

Michael Bourn gave the Astros an early lead with a two-run single in the second inning.

Wandy Rodriguez tied a season high by allowing 10 hits and gave up three runs with four strikeouts in seven innings. He was replaced by Wilton Lopez, who pitched a perfect eighth before Mark Melancon (3-1) in the ninth.

Pence doubled with two outs in the seventh inning to extend his hitting streak to 15 games. Ondrusek intentionally walked Brett Wallace before walking Chris Johnson to load the bases, but a pop fly by Matt Downs ended the inning.

Nick Masset pitched a scoreless eighth for Cincinnati.

Heisey's pinch-hit homer off Rodriguez bounced off the inside of the pole in left field and got Cincinnati within 3-2 in the seventh inning. Stubbs followed with his shot to right field that tied at 3-all.

Edgar Renteria reached on an error by third baseman Johnson after the second homer and before a single by Brandon Phillips left runners at the corners with two outs. Jonny Gomes grounded into a force out to end the inning with the game tied.

Sam LeCure pitched two scoreless innings after starter Edinson Volquez left before Logan Ondrusek took over for the seventh inning.

Volquez gave up three hits and three runs with five walks in four innings, his shortest outing of the season.

Joey Votto singled in the sixth inning before Rodriguez struck out Phillips. Jonny Gomez singled but Rodriguez retired the next two batters to get out of that inning.

Cincinnati's first run came when Votto tripled and scored on a groundout by Brandon Phillips with no outs in the fourth inning to make it 3-1. Ramon Hernandez singled with two outs but Rodriguez struck out Jay Bruce to escape the inning.

Houston added a run in the third inning when Wallace scored on a sacrifice fly by Downs. Volquez walked Pence before he was out on a force out by Wallace. Johnson followed with a double to left field to send Wallace to third before Downs' sacrifice.

Volquez walked three straight with one out in the second before retiring Rodriguez to set up Bourn's two-out, two-RBI single.

Phillips robbed Johnson of a hit for the second time in the series when he made a leaping, midair catch for the first out in the second inning. On Monday, Phillips made a nifty diving catch that ended in a belly flop.
