Though he pitched in only four games for the Angels in 2012, Cassevah made 50 appearances for the club since his big league debut in April of 2010. He owns a 3.20 ERA in 64 2/3 innings pitched, with 34 strikeouts against 33 walks. Perhaps most appealing to the Rockies, he has a 65.9 percent groundball ratio.
Pitchers and catchers reported to the Rockies Minor League camp Saturday, with position players reporting Friday. Cassevah can expect at least an appearance or two in Cactus League play as his new club gets a close look at him. He made one spring appearance with the Angels on Feb. 24, throwing one scoreless inning while allowing a hit and two walks.
