Thursday, Belisario, 32, threw his first bullpen since fracturing his left shoulder in a swimming pool accident. Heading into Spring Training, he looked like a good candidate to earn a spot in the bullpen. He went 4-8 with a 5.56 ERA for the White Sox in 2014.
"He's going to help us as soon as he gets built up," Rays manager Kevin Cash said. "But everybody's really optimistic where he's at."
Cash called Belatti and Stowell "good guys."
"They backed up a lot of games," Cash said. "We appreciated their patience, but it was time to get them ready for their seasons."
Cash liked Velez's versatility.
"Nice player to have and he can hit," Cash said. "So we enjoyed having him here."
