Newly promoted Oneil Cruz drove in four runs and Bligh Madris got three hits in his major league debut, sparking the Pittsburgh Pirates to a 12-1 romp over the Chicago Cubs on Monday night.

Both rookies were called up from Triple-A Indianapolis earlier in the day and they delivered right away.

Cruz, considered Pittsburgh's top prospect, hit a three-run double to deep center field that capped a four-run third inning to push the Pirates' lead to 7-0. He was playing in the third big league game of his career.

The 6-foot-7 Cruz also hit an RBI single in a five-run seventh as the Pirates set a season high for runs. He started the final two games of last season when he became the tallest shortstop in major league history.

Cruz's double had an exit velocity of 112.9 mph, his throw to first base on a groundout was clocked at 96.7 mph and his sprint speed registered as high as 31.5 feet/second while running the bases. All are among the highest marks by a Pirates player since the MLB Statcast era began in 2015.

Madris hit a two-run single in the second inning in his first at-bat in the majors. The outfielder keyed a three-run inning that included the first of Hoy Park's two sacrifice flies.

Madris became the first Pirates player to have a three-hit game in his debut since Jason Kendall in 1996.

JT Brubaker (1-7) pitched six scoreless innings for his first win since last Aug. 24, a span of 14 starts.

Brubaker scattered five hits while striking out five and walking three. He has a 2.65 ERA in his last six starts.

The Pirates took advantage of five walks by rookie Caleb Kilian (0-2), who was tagged for seven runs in 2 1/3 innings. Kilian was making his third career start.

Daniel Vogelbach hit a two-run double in the Pirates' big seventh inning and Tyler Heineman's RBI double made it 12-1.

The Cubs scored their run in the seventh on Ian Happ's single. Happ, Rafael Ortega and Nico Hoerner had two hits apiece.

Both teams came into Monday having lost 11 of their last 13 games.

Cubs rookie RHP Matt Swarmer (1-2, 5.23 ERA) will make his fifth career start Tuesday night. Pirates rookie RHP Roansy Contreras (1-1, 3.06) has allowed four runs in each of his last two starts.
