Top Yankees prospect Luis Severino immediately showed the potential that launched him to the first Triple-A start of his career, striking out his first batter, Henry Urrutia.

And though Severino, 21, had an uneven debut Sunday and failed to dominate as he had in Double-A, he didn't come unglued, either.

Severino, the Yankees' top pitching prospect, allowed five hits, two runs and three walks in 4 1/3 innings, striking out three for Scranton/Wilkes-Barre during a 7-2 loss to Norfolk.

Leftfielder Ben Gamel was 2-for-5 with a triple, and third baseman Cole Figueroa went 2-for-4 for the RailRiders (26-25, T-2nd International League North, 1.5 games back).

After striking out Urrutia, Severino allowed a single to Rey Navarro. But Severino escaped any possible trouble by getting Chris Parmelee to fly out and then picking off Navarro.

With two outs in the second inning, Norfolk's David Freitas doubled and scored on Michael Amanzar's double. Severino then walked Julio Borbon before getting Derrik Gibson to ground out to end the inning.

A two-out walk in the third and two-out single in the fourth were his only blemishes during those innings, but Severino walked Gibson to start the fifth. He struck out Urrutia for the second time, but Navarro's second single ended Severino's day. Lefthander Tyler Webb replaced Severino and allowed Gibson to score on an RBI single before getting the final two outs of the inning.

Severino threw 57 of his 91 pitches for strikes.

In eight games with Double-A Trenton, Severino struck out 48 and walked 10 in 38 innings, allowing 32 hits with a 3.32 ERA.
