The Tampa Bay Rays have acquired help for an inconsistent bullpen, obtaining left-handed reliever Dan Jennings from the Chicago White Sox for minor league first baseman Casey Gillaspie.
Jennings was 3-1 with a 3.45 ERA in 48 appearances for the White Sox this season. He is expected to join the Rays in New York for the start of a four-game series Thursday night.
Tampa Bay cleared room on the 40-man roster by designating right-handed reliever Diego Moreno for assignment. A corresponding move to the 25-man roster will be announced before Thursday night's game.
The Rays also say rookie right-hander Austin Pruitt has been added to the taxi squad. He will start Friday against the Yankees, filling in for injured right-hander Jake Odorizzi.
