Ely, 26, is 4-13 with a 5.70 ERA over three seasons with the Dodgers after being acquired from the White Sox, who selected him in the third round of the 2007 MLB First-Year Player Draft. Ely spent the majority of last season at Triple-A Albuquerque, where he went 14-7 with a 3.20 ERA and led the Pacific Coast League in ERA, strikeouts (165) and WHIP -- walks and hits per innings pitched (1.10). He also tied for the league in wins and ranked second in innings pitched, with 168 2/3.
Rasmussen, 23, a native of Arcadia, Calif., and a former standout at UCLA, was the Marlins' second-round pick in 2010. The Astros acquired him on July 4, 2012, as part of the deal that sent Carlos Lee to Miami. Rasmussen went 4-4 with a 4.80 ERA in 11 games, including 10 starts, at Double-A Corpus Christi in 2012, and is 20-21 with a 3.88 ERA in 60 career games, including 53 starts.
It could be called a case of the Dodgers finally getting their man. Los Angeles selected Rasmussen out of Polytechnic High School in Pasadena, Calif., in the 27th round of the 2007 Draft, but he opted to go to UCLA.
The Dodgers have 39 players on their Major League roster, one below the limit.
The Astros also announced that right-handed pitcher Mickey Storey, designated for assignment on Monday, was claimed off waivers by the Blue Jays. To make room for Ely, Houston designated outfielder Che-Hsuan Lin for assignment.
It marks the third time this winter that Storey, 26, has been claimed off waivers since the Astros designated him for assignment after the 2012 season. He was claimed by the Yankees on Nov. 20, the Astros on Dec. 6 and now the Blue Jays.
