Billy Hamilton scored the go-ahead run in the 13th inning to cap a memorable first career start in the Cincinnati Reds' 6-5 victory over the Houston Astros.

Hamilton filled nearly his entire box score line with three hits, two walks, two runs scored, an RBI and four steals. The rookie speedster worked a leadoff walk in the 13th, and following walks to Shin-Soo Choo and Joey Votto, trotted home on Jay Bruce's two-run double off the wall in left-center field.

Bruce, a native of Beaumont, TX, batted 7-for-13 with 10 RBI during the three- game sweep following his three-hit, three RBI night.

Alfredo Simon (6-4) worked out of jams in each of his three innings of relief to pick up the win, which moved the Reds a half-game behind the wild-card leading Pirates. Cincinnati hosts Pittsburgh in a three-game series over the weekend.

Aroldis Chapman gave up a run in the 13th on Trevor Crowe's groundout, and needed to retire Chris Carter with two on to close out his 37th save of the season.

Jorge De Leon (0-1) was handed the loss after serving up Bruce's go-ahead hit. Brandon Barnes belted a solo homer and Carlos Corporan drove in two runs for the Astros, who went 3-for-21 with runners in scoring position and stranded 16 baserunners.

The Reds left 15 runners on.

Extra innings were needed after both teams left the bases loaded in the ninth. Opportunities remained aplenty from the 10th through the 12th, when a combined eight runners were left stranded.

The Reds used seven relievers after starter Greg Reynolds was pulled with two outs in the fourth, having given up two runs on four hits. Astros starter Brad Peacock was charged for four runs -- three earned -- on six hits and three walks over 5 2/3 innings.

Choo and Votto, who rank second and first, respectively, in on-base percentage in the NL, each worked walks in the first inning. Choo came around on Bruce's double into the right-field corner, and Votto raced home on Ryan Ludwick's sacrifice fly.

Choo added an RBI single in the second after Hamilton reached with a two-out double -- the rookie's first hit in his fourth career at-bat.

Barnes barely cleared the right-field wall in the third, and the Astros pushed another run across in the fourth on Corporan's bases-loaded sac fly.

Hamilton's third hit, a dribbler off the third-base bag, plated Todd Frazier in the sixth, but the Astros answered with two runs in the bottom half via three consecutive doubles.

L.J. Hoes' pinch-hit double and Corporan's two-bagger that landed on Tal's Hill in center field each drove in a run, the latter tying things at 4-4.
