PITTSBURGH — Jose Osuna, called up from the minor to serve as an extra player for the second game of a doubleheader, hit a three-run homer to lift the Pittsburgh Pirates to an 8-3 victory on Wednesday night and a split with the Detroit Tigers.

Major League Baseball rules allow teams to carry a 26th man in second games and the Pirates recalled the right-handed hitting Osuna from Triple-A Indianapolis to play right field against lefty Matthew Boyd. Osuna then opened the scoring with a shot to center field in the second inning.

In the first game, Nicholas Castellanos had four hits and a key home run, and the Tigers used 20 hits to outslug the Pirates 13-10. The teams combined for 34 hits, including four from Detroit slugger Miguel Cabrera and three from Jeimer Candelario, who scored five runs.

Chad Kuhl (3-1) tied a career high with eight strikeouts in six innings in the second game. He allowed three runs, six hits and one walk in improving to 3-0 lifetime against Detroit.

Boyd (1-1) gave up four runs and seven hits in 3 2/3 innings. He had given up just three runs in his first three starts and 19 1/3 innings.

Elias Diaz had three hits and Starling Marte drove in two runs for the Pirates.

In the opener, Candelario homered and doubled. James McCann also went deep for Detroit.

Pittsburgh’s Francisco Cervelli had three hits and a career-high six RBIs, including a three-run homer. His two-run double in the eighth made it 12-10.
