Reds 6, Astros 5 (13): Jay Bruce doubled home two runs in the top of the 13th inning and finished with three hits and three RBIs as visiting Cincinnati completed a three-game sweep.

Billy Hamilton, who ignited the winning rally with a leadoff walk, collected his first three career hits and became the first player since 1920 to steal four bases in his initial major-league start as the Reds pulled within one-half game of Pittsburgh for the top National League wild-card spot.

Alfredo Simon (6-4) worked three scoreless innings and Aroldis Chapman allowed a run in a shaky 13th before securing his 37th save to keep Cincinnati 2 1/2 games behind first-place St. Louis in the NL Central. The Reds also moved 5 1/2 games ahead of Washington for the second wild card.

Three walks, a stolen base and a wild pitch by Jorge De Leon (0-1) loaded the bases for Bruce, who hammered a double off the wall in left-center to finish 7-for-13 with 10 RBIs in the series and send Houston to its fifth straight defeat. Brandon Barnes homered and Carlos Corporan drove in a pair of runs for the Astros.

Bruce had an RBI double in a two-run first and Hamilton doubled - his first career hit - and scored on Shin-Soo Choo's single in the second to stake the Reds to a 3-0 lead. Hamilton's first career RBI in in the sixth made it 4-2, but Houston tied it in the bottom of the inning on consecutive run-scoring doubles by L.J. Hoes and Corporan.

Reds 1B Joey Votto went 0-for-4 and had his 23-game hitting streak at Minute Maid Park snapped. It was the longest run in the stadium's history.
