Karns, Rivera lead Rays against Orioles

Starter throws four perfect innings; backstop delivers power

Karns, Rivera lead Rays against Orioles

SARASOTA, Fla. -- Nathan Karns is not an attorney, but when it comes to his possible inclusion in the Rays' starting rotation, the 27-year-old right-hander is making quite an argument.

Facing a Baltimore Orioles' lineup consisting largely of likely Opening Day starters, Karns hurled four innings of no-hit baseball on Saturday, striking out two and walking none as the Rays rode a Rene Rivera two-run homer to a 3-2 victory over the O's in Sarasota, Fla.

"It was great to be out there, finally working with Rivera," said Karns, who has now allowed three hits and one earned run in nine Grapefruit League innings, with four strikeouts and two walks. "I felt like he did a great job managing the game … [giving me] easy reminders behind the dish to keep me locked in.

"We're getting closer to the season, everybody's playing their hearts out and it's a fun time right now."

Rivera, acquired in the trade that sent outfielder Wil Myers to San Diego, launched a one-out drive off Orioles left-hander Tim Berry in the fourth inning with John Jaso aboard to give the Rays a lead they would never relinquish.

Brian Matusz, who was given a rare starting assignment to work primarily on his changeup, breezed through three scoreless innings for the Orioles, allowing two hits and no runs while striking out three and walking none.

"Once you get out there on the mound, it's really the same game," Matusz said of his one-day conversion from reliever to starter. "You've still got to make pitches and get hitters out."

"It was just a matter of relearning the pregame routine of when to get out, when to start playing catch and things like that. It was nice to have guys like [Chris] Tillman around to help."

Jaso scored the third Tampa Bay run on a ground-rule double to left by Kevin Kiermaier in the sixth inning off Chaz Roe.

A sixth-inning double by J.J. Hardy off Steve Geltz knocked in Rey Navarro with the first Orioles' run, and Steve Pearce launched a solo home run to center off Robert Zarate in the seventh to round out the Baltimore scoring.

Up Next:: The Rays return to action Sunday when they host the New York Mets in Port Charlotte, Fla., at 1:05 p.m. ET. Matt Andriese, who has shown promise in two Grapefruit League outings this spring as he battles for a spot in the Tampa Bay rotation, will be opposed by veteran right-hander Bartolo Colon.
