ATLANTA — Tim Hudson gave up only four hits and no earned runs in 7 1-3 innings to remain unbeaten in his career against Houston, and the Braves stayed hot with a 4-1 win Friday night that left the Astros with their worst 32-game stretch in franchise history.
The Astros are 3-29 in their last 32 games. Houston's worst 32-game stretch before the 2012 season was 5-27, most recently from June 26 to July 29, 1962 as the Colt .45s, according to STATS LLC.
The Braves improved to 7-1 on their 10-game homestand.
Hudson (11-4) improved to 5-0 in seven career starts against the Astros. He allowed one unearned run, four hits and two walks and has won five straight decisions.
Chipper Jones had a two-run double in Atlanta's three-run third inning. Martin Prado had two doubles, including a run-scoring hit in the fourth.
Craig Kimbrel struck out the side in the ninth to earn his 31st save.
Atlanta trails first-place Washington by 2 games in the NL East after the Nationals split a doubleheader with Miami on Friday.
Right-hander Armando Galarraga (0-1) gave up four runs, five hits and a career-high seven walks in 5 1-3 innings. He made his second start with Houston following his recall from Triple-A Oklahoma City on July 28.
Jones' third-inning double drove in Prado, who doubled, and Jason Heyward, who walked. Jones scored when shortstop Marwin Gonzalez lost Dan Uggla's high popup, which dropped in shallow left field for a double.
Prado's RBI double in the fourth gave Atlanta a 4-0 lead.
The Astros scored an unearned run off Hudson in the sixth. Ben Francisco had an infield hit and moved to second on Uggla's throwing error. Francisco scored from third on a groundout by J.D. Martinez.
Tensions rose in the sixth inning as Galarraga and Prado exchanged stares as each backed away during a long at-bat. Prado and catcher Carlos Corporan exchanged words, prompting Michael Bourn, who was on first base following a walk, and first-base coach Terry Pendleton to take a few steps toward the mound. Umpires stepped in to prevent an altercation.
Galarraga walked Prado on the next pitch and was pulled from the game.
Jim Joyce, who had the blown call that prevented Galarraga from recording a perfect game with the Tigers on June 1, 2010, was the third-base umpire.
Right-hander Mickey Storey recorded two outs in his major league debut following his call-up earlier Friday from Oklahoma City.
Jordan Schafer had one hit in his first return to Atlanta since his July 31, 2011 trade from the Braves.
NOTES: Houston placed RHP Francisco Cordero on the 15-day DL with an inflamed right big toe. Cordero, who came to Houston on July 20 in a trade with Toronto, is 0-3 with a 19.80 ERA and three blown saves in six games with the Astros. Overall, he has a 7.55 ERA.
