Rays designated RHP Ernesto Frieri for assignment.
The Rays bought low on Frieri over the winter in hopes that he would show his old form, but he posted a mediocre 4.63 ERA and 19/11 K/BB ratio over 23 1/3 innings while allowing six home runs. He has an $800,000 guarantee with Tampa Bay.
The Dodgers are expected to call up left-hander Ian Thomas on Tuesday.
He'll serve as the 26th man for Tuesday's doubleheader against the Rockies. Thomas, who was recently acquired from the Braves in the Juan Uribe deal, has a 3.94 ERA and 18/11 K/BB ratio over 16 innings in the majors.
Juan Nicasio will start the first game of Tuesday's doubleheader against the Rockies.
Nicasio has a solid 1.29 ERA and 28/11 K/BB ratio in 21 innings this season, but he hasn't thrown more than 38 pitches in an appearance this season. In other words, look for this to be a bullpen game for the Dodgers.
Rajai Davis is expected to be placed on the paternity leave list Tuesday.
Davis has left the team in order to be present for the birth of his second child. He can be away from the team for 24 to 72 hours. Daniel Fields is set to be called up to replace him on the active roster.
The Tigers are expected to promote outfielder Daniel Fields from Triple-A Toledo on Tuesday.
Meanwhile, Rajai Davis is expected to be placed on the paternity leave list. Fields, 24, is batting .271/.394/.486 with three home runs, 21 RBI, and nine stolen bases over 48 games this season in Triple-A. He'll be making his major league debut.
