Yankees prospect Severino throws six hitless innings

Righty tosses gem for Class A Tampa, but bullpen can't complete combined no-hitter

Right-hander Luis Severino, the Yankees' No. 9 prospect, threw six hitless innings Wednesday. While Class A Advanced Tampa's bullpen was unable to complete the combined no-hitter, the Yankees easily defeated Clearwater, 9-3.

Severino was making his second start since being promoted to Tampa. He retired the first 10 batters he faced, before issuing a walk to Phillies' No. 3 prospect J.P. Crawford. Undeterred, Severino set down the next eight hitters in order to end his day.

The combined no-hitter quickly came to an end when right-hander Stefan Lopez relieved Severino to start the seventh inning. Crawford led off with a single, and the Threshers went on to score three runs on two hits and a walk in the inning.

Severino struck out six batters and induced eight ground-ball outs Wednesday. It was his first hitless outing since June 5, 2012, when, in his professional debut, he didn't allow a hit in five innings with the Yankees' Dominican Summer League affiliate.

Severino's latest gem came a day after it was announced that he would represent the World team in the Sirius XM All-Star Futures Game next month at Target Field. The Dominican native began the season with Class A Charleston, where he posted a 2.79 ERA and struck out 70 batters in 67 2/3 innings. He was promoted to Tampa after the South Atlantic League All-Star break last week.

Tampa gave Severino plenty of run support Wednesday. First baseman Greg Bird, the Yankees' No. 6 prospect, went 3-for-5 with a run and a walk. Right fielder Aaron Judge, the club's No. 8 prospect, added a two-run triple, two walks and a run.
