UPDATE, 4:51: With Dominguez replacing Yates, Rays now have a major-league most 8 rookie on 25-man roster.
UPDATE, 4:45: Dominguez said he was pleased to get called up and ready to show he can pitch regularly in the majors. ... Kiermaier said he welcomes the chance to play vs. a LHP and hopes to get the opportunity to be an everyday player.
UPDATE, 3:42: Lefty-swinging Kevin Kiermaier gets a start vs. LHP Mark Buehrle today, and Desmond Jennings is the DH.
Also, the Rays have assigned RHP Ronald Belisario, who was sidelined during the first part of spring training with a left shoulder fracture, to Triple-A Durham.
DEVELOPING: The Rays take on the Jays again tonight in Toronto, seeking to push their winning streak to five.
The biggest issue may be getting a solid start from RHP Erasmo Ramirez, who struggled mightily pitching in relief on Friday in Miami.
Ramirez, acquired March 31 from Seattle, is filling the fifth starter spot tonight. The biggest key will be to not fall behind hitters, as he did against the Marlins, allowing seven runs, on six hits, over two innings.
Despite having nine players on the DL, the Rays are off a 5-3 start that matches their best eight-game record, also 2010. Kevin Cash is the first Rays manager to win five of his first 8 games.
The Rays added a fresh arm to their bullpen, calling up RHP Jose Dominguez to take the place of RHP Kirby Yates, who was optioned to Triple-A.
