CHICAGO -- Tim Anderson homered and drove in three runs, Miguel Gonzalez tossed eight strong innings and the Chicago White Sox beat the Houston Astros 7-1 on Wednesday night, their second straight win over the team with the best record in the AL.
Leury Garcia and Yolmer Sanchez each had two-run singles as Chicago won consecutive games for just the second time since last month's All-Star break.
Gonzalez (6-10) allowed one run on five hits to record the 50th win of his career. He bounced back after getting shelled for seven runs on seven hits in 1 2/3 innings against Boston last Thursday.
Derek Fisher homered leading off the eighth for Houston's only run. George Springer went 1 for 4 in his return from the 10-day disabled list. The Astros have dropped three of four overall and four straight on the road.
Chicago rookie Yoan Moncada went 1 for 2 with two walks and has reached safely in 14 of his last 25 plate appearances.
Houston starter Colin McHugh (0-1) escaped a bases-loaded, no-out jam in the second inning, but Chicago broke through for four runs in the fifth.
Nicky Delmonico led off with a single and Anderson followed with a homer to make it 2-0. The next batter, Omar Narvaez, kept the rally going with a single and one out later Garcia hit a ground-rule double to put runners on second and third. Sanchez then singled to left to score both runners for a 4-0 lead.
The White Sox tacked on three runs in the sixth to knock out McHugh. He allowed seven runs on nine hits in 5 1/3 innings.
To make room for Springer on the roster, the Astros optioned 1B Tyler White to Triple-A Fresno. Manager A.J. Hinch said it was a tough decision. "Tyler White deserved to stay," Hinch said. "There's only 25 roster spots." White, 26, batted .310 with three homers and nine RBI in nine games with Houston.
The White Sox announced a minor trade before the game, acquiring RHP Steve Johnsonfrom Baltimore for cash considerations. Johnson, 29, was assigned to Triple-A Charlotte.
Astros: RHP Michael Feliz(right shoulder discomfort) is expected to begin throwing soon. He was placed on the 10-day DL on Aug. 1. . C Evan Gattis is still experiencing symptoms after being placed on the 7-day concussion DL on Saturday.
White Sox: OF Avisail Garcia, who returned from the DL on Tuesday, said he still has inflammation in his right thumb but hopes to play through it. "Sometimes it hurts, sometimes no," he said.
Astros righty Brad Peacock (10-1, 3.20 ERA) will be matched against lefty Carlos Rodon (1-4, 4.66) in the series finale on Thursday night. Peacock got the win in his last start against Toronto despite allowing seven runs in six innings. Rodon tied his season high with 11 strikeouts against Boston on Aug. 4.
