PITTSBURGH — Joe Musgrove came off the disabled list to win his Pirates debut with seven scoreless innings on the mound while also getting his first career hit and scoring the winning run as Pittsburgh beat the St. Louis Cardinals 8-1 on Friday night.

The right-hander singled to lead off the sixth inning, when the Pirates scored three times off John Gant to break a scoreless tie. Musgrove came home on Josh Harrison’s double to center field before Josh Bell hit a sacrifice fly and Corey Dickerson capped the inning with an RBI triple off Brett Cecil.

Musgrove (1-0) allowed five hits and struck out seven. He did not walk a batter while throwing just 67. Musgrove was activated before the game after being sidelined all season with a strained right shoulder. He was one of four players acquired from the Houston Astros in a January trade for right-hander Gerrit Cole.

Gant (1-2) allowed just two singles through the first five innings before Musgrove led off the sixth with his single. Gant ended up being charged with three runs in 5 1/3 innings while giving up four hits with seven strikeouts and no walks.

Francisco Cervelli broke the game open with a three-run double in the seventh inning that pushed Pittsburgh’s lead to 6-0. The Pirates won for just the second time in seven games, but improved to 12-5 inside the NL Central and 4-0 against St. Louis.

Tommy Pham accounted for the Cardinals’ run with an eighth-inning homer, his ninth, off Michael Feliz that snapped an 0-for-16 skid. St. Louis lost its third straight game.

Austin Meadows and Jordy Mercer hit back-to-back triples for the Pirates in the bottom of the eighth. Meadows is 13 for 29 (.448) with three home runs, five runs scored and five RBs in his first six career games.

Harrison, Bell, Dickerson, Meadows and Mercer each had two of Pittsburgh’s 12 hits.

St. Louis’ Marcell Ozuna and Jedd Gyorko had two hits apiece. Ozuna returned to the lineup after being scratched from Wednesday’s loss to Kansas City when he overslept and arrived late to the ballpark.

Kontos DFA’d

Pirates right-handed reliever George Kontos was designated for assignment to clear a roster spot for Musgrove. Kontos was removed from his role as the primary setup man for closer Felipe Vazquez last week. In 21 games, he was 2-3 with one save and a 5.03 ERA.
