Left-hander Daniel Norris struck out nine batters in five innings and outfielder Dalton Pompey singled in his Triple-A debut Thursday, as Buffalo defeated Scranton/Wilkes-Barre at home, 5-1.
Norris, the Blue Jays' No. 1 prospect, held the RailRiders to one run on one hit -- a solo home run -- and three walks. He threw 79 pitches and picked up his third win in as many starts since he was promoted from Double-A New Hampshire earlier this month.
Norris, ranked No. 28 on MLBPipeline.com's Top 100 Prospects list, also nearly became the second pitcher in Buffalo's modern era (since 1985) to strike out at least 10 batters in three games in a season. The only Bison to have done so was Matt Harvey, who didn't record his third double-digit strikeout game until his 14th start in the 2012 season.
Across three levels this season, Norris is 12-1 with a 2.20 ERA. He ranks fourth among all Minor Leaguers with 157 strikeouts in 118 2/3 innings.
Pompey, the Blue Jays' No. 3 prospect and No. 91 on the Top 100, was promoted from New Hampshire on Wednesday and debuted with Buffalo on Thursday. He led off and played center field and went 1-for-4 with two strikeouts at the plate.
While Norris and Pompey were starring for Buffalo, right-hander Roberto Osuna was making his best start of the season for Class A Advanced Dunedin as he continues to work back from Tommy John surgery. The Blue Jays' No. 5 prospect struck out five batters, walked none and allowed three hits in four scoreless innings Thursday.
Osuna underwent Tommy John surgery last July and returned to taking a regular turn in the rotation this month. Thursday was his fifth start for Dunedin and his longest appearance since his surgery.
