PITTSBURGH (AP) — Pinch-runner Jason Martin scored the winning run on catcher Yasmani Grandal’s error in the bottom of the ninth inning as the Pittsburgh Pirates rallied for a 5-4 victory over the Chicago White Sox on Tuesday night.

With the score tied at 4-4, the Pirates loaded the bases with none out as Gregory Polanco and Josh Bell singled and Ke’Bryan Hayes walked.

Kevin Newman then laid down a bunt. Pitcher Jimmy Cordero fielded the ball and shoveled it to Grandal in attempt to get a force out at home plate, but Grandal dropped the toss and Martin, who ran for Polanco, scored.

Newman started the game-tying rally in the eighth inning with a double as the Pirates scored twice. After Jacob Stallings followed with another double to drive in Newman, Erik Gonzalez flared an RBI single into left field to make it 4-4.

Richard Rodriguez (2-2) pitched a scoreless ninth for the win.

Grandal hit a two-run home run and Jose Abreu extended his hitting streak to 21 games for the White Sox.

Grandal’s blast capped a three-run fifth inning that broke a scoreless tie and included an RBI single by Yoan Moncada. Abreu kept his streak going in the eighth when he singled.

WEARING NO. 21

All Pirates players and coaches will wear No. 21 in Wednesday night’s game against the White Sox as part of Roberto Clemente Day. Major League Baseball has also given permission for players of Puerto Rican descent on other teams to wear the number for the day.

The Pirates and the family of the late Hall of Fame right fielder are hoping to spark a movement in which No. 21 will be retired throughout Major League Baseball.
