PITTSBURGH — Paul Skenes struck out seven over four-plus innings in his major league debut and Yasmani Grandal hit a go-ahead three-run homer as the Pittsburgh Pirates edged the Chicago Cubs 10-9 on Saturday.
Skenes, the top overall pick in the 2023 draft, showed flashes of why he is considered perhaps the best pitching prospect in a generation. The 21-year-old — who was greeted by a standing ovation by most of the near-capacity crowd, including girlfriend Livvy Dunne — reached 100 mph on 17 of his 84 pitches.
He was electric at times but hardly perfect. Skenes allowed at least one runner in every inning he started — including a solo homer by Nico Hoerner in the fourth — and was pulled after allowing a pair of hits leading off the fifth. He was charged with three runs on six hits with two walks and a hit batter.
''The stuff was really good, I think,'' Skenes said. ''Just got to get ahead of hitters a little bit, more consistently. But, I think that'll come.''
Pittsburgh's bullpen imploded immediately after Skenes' exit, allowing Chicago to score seven runs to take the lead, with six coming on walks with the bases loaded, most of them on counts that weren't even competitive.
Pirates relievers Kyle Nicolas, Josh Fleming and Colin Holderman (1-0) threw 26 balls in a span of 31 pitches sandwiched around a 2 hour, 20 minute rain delay in the top of the fifth.
The Pirates' offense, stagnant for most of the last month, picked up the slack.
Grandal's first home run with the Pirates — a shot to the seats above the 21-foot-high Clemente Wall in right field off Keegan Thompson (1-1) — put Pittsburgh back in front in the bottom of the fifth.
