ARLINGTON, Texas -- Three-time Cy Young Award winner Max Scherzer settled down after a shaky start to win his debut for the American League West-leading Texas Rangers, striking out nine over six innings and getting some help from his new teammates as they beat the Chicago White Sox 5-3 on Thursday.

Four of Chicago's first five batters reached base in a three-run first inning when Scherzer (10-4) threw 37 pitches. The White Sox then had three singles in the second, though Scherzer benefitted from a double-play grounder and an inning-ending strikeout to prevent any more runs.

Scherzer, acquired from the New York Mets in a trade over the weekend and signed through next season, allowed seven singles and walked two. The right-hander retired 13 of the last 14 batters he faced, with seven of his strikeouts coming in that span. A week after his 39th birthday, he threw 70 of 105 pitches for strikes, with 21 of those swing-and-miss strikes.

Mitch Garver led off the Rangers' fourth against Touki Toussaint (1-4) with a 457-foot homer into the second deck of seats in left-center to tie the game at 3. Three batters later, Marcus Semien homered for the second game in a row, his 17th of the season, a solo shot that put Texas ahead to stay.

Garver added an RBI single in the eighth as the Rangers completed a three-game sweep. The White Sox, who have lost 18 of 24 overall, had scored only one run combined in their previous three games before that three-run first inning.

Will Smith worked the ninth for his 19th save in 21 chances. That came after Josh Sborz and Aroldis Chapman, the hard-throwing reliever acquired in a trade from the Kansas City Royals more than a month ago, worked scoreless innings.

Toussaint struck out nine and walked four in his 5 1/3 innings.

Tim Anderson and Andrew Benintendi both blooped opposite-field singles on 0-1 counts to open the game against Scherzer, who then struck out Andrew Vaughn before consecutive walks -- the second to Yasmani Grandal to force in a run. Scherzer then picked up another strikeout and had a 0-2 count before Gavin Sheets grounded a two-run single up the middle to put the White Sox up 3-0.

Josh Smith had an RBI double in the second for the Rangers, and Adolis Garcia extended his AL-leading RBI total to 86 with his single in the third.
