Rivero arrives at Nationals camp

VIERA, Fla. -- Left-hander Felipe Rivero arrived at Space Coast Stadium on Friday, one day after being acquired from the Rays in the Jose Lobaton trade.

Rivero went to Rays camp on Monday and was surprised to learn a few days later that he had been dealt after spending five years in that organization.

"I was shocked. [The Rays] called me into the office and told me that I have been traded," Rivero said. "They told me yesterday, and I was practicing over there. It was pretty hard on me."

There was one consolation, however, with Lobaton part of the trade.

"When I heard that he was traded with me, I was very excited, because I don't know anybody on the team," he said. "I played with him [during Spring Training]. He is one of the guys that I know."

Rivero won a career-high nine games and posted a 3.40 ERA in 25 games (23 starts) last season for Class A Charlotte. He represented the Rays at the Sirius XM All-Star Futures Game at Kauffman Stadium in 2012 while pitching for Bowling Green, and he earned an All-Star nod from the Midwest League. His fastball can hit 96 mph, and he has a good breaking ball.

The Nationals will watch Rivero pitch in canmp before deciding where he will start the season.
