At 43-22, the White Sox have the second-best home record in the American League behind Oakland (44-21).
Chicago is 15-3 at home since the All-Star break. The White Sox routed Texas 13-2 on Saturday, improving to 6-0 on their seven-game homestand.
Chicago maintained a one-game lead over Kansas City atop the AL Central.
“The offense has been exploding at home,” said Chicago’s Mark Buehrle, who pitched six solid innings for the win Saturday. “Everybody is clicking—it’s not like we have one or two guys on the offense working.”
Thomas homered twice and drove in five runs for Chicago for Saturday, giving him six home runs and 12 RBIs on the homestand. He has hit 26 of his 34 home runs at home.
“We seem to have things really rolling at home,” Thomas said. “Just relaxing and just getting good pitches to hit—I’m having one of those periods where I’m just getting good results out of my swing.”
A victory Sunday will give the White Sox their first four-game sweep of the Rangers, who have lost three in a row after winning a season-high eight straight.
Texas will send its ace John Thomson to the mound in the finale.
The Rangers have won each of Thomson’s last six starts, with the right-hander going 4-0 over that span.
Thomson allowed four earned runs and 11 hits over eight innings on Tuesday in a 5-4 win at Detroit. He hasn’t lost since July 22 at Baltimore, and has given up three earned runs or fewer in four of his last six outings.
