CHICAGO (Interstat) — Davis Martin pitched six shutout innings and Luisangel Acuña drove in the go-ahead run as the Chicago White Sox defeated the Atlanta Braves 2-1 on Wednesday night at Guaranteed Rate Field.

Martin allowed six hits, struck out six and walked none, improving to 9-2. Bryan Hudson pitched a scoreless ninth for his third save. Chris Sale took the loss, falling to 8-5, after surrendering two runs in six innings.

The White Sox took the lead in the fourth inning. Braden Montgomery led off with a double to left field. Derek Hill followed with a sharp single to center that scored Montgomery, tying the game at 1-1. Hill advanced to third on a groundout by Jacob Gonzalez, then scored on a groundout from Acuña to give Chicago a 2-1 lead.

Atlanta had its best chance to answer in the seventh. Jorge Mateo singled to lead off, and after Austin Wynns lined out, Mateo moved to second on a strikeout. Ozzie Albies then reached on a fielding error by third baseman Miguel Vargas, allowing Mateo to score and cutting the deficit to 2-1. Matt Olson walked, but Dominic Smith popped out to end the threat.

Martin escaped a jam in the second, when Atlanta loaded the bases with one out on a single by Mauricio Dubón, a hit batter and a single by Mike Yastrzemski. Martin struck out Jorge Mateo and got Austin Wynns to line out.

Chicago’s bullpen held the lead. Seranthony Domínguez pitched a 1-2-3 eighth, and Sean Newcomb worked a scoreless seventh with one hit allowed and a strikeout.

The Braves scored their only run in the seventh, an unearned run that broke a streak of 17 consecutive scoreless innings by White Sox pitchers against Atlanta dating to the previous night’s 10-inning contest. Chicago’s defense turned in a key play in the bottom of the seventh when third baseman Austin Riley threw wide to home on a fielder’s choice that cut down Acuña at the plate, preserving the lead.

Atlanta, which entered with a major-league best 45-23 record, had won four of its previous five games. The White Sox improved to 36-31.
