Angels reliever Jose Arredondo will have Tommy John surgery on his right elbow in January and will miss the entire 2010 season, the club confirmed on Friday.

Arredondo is coming off a disappointing 2009 campaign in which he posted a 6.00 ERA in 43 appearances after recording an impressive 1.62 ERA in 52 appearances as a rookie in '08.

The right-hander continued his high strikeout rate with 47 K's in 45 innings last season but saw his walks and homers increase while losing velocity on his fastball.

He began the season with the Angels but was sent down to Triple-A Salt Lake on June 10 after carrying a 5.55 ERA through his first 25 appearances.

The 25-year-old was then placed on the disabled list with a sprained ligament in his elbow but appeared to get back on track with a 2.18 ERA in 19 appearances with the Bees and was called up on Aug. 6.

Arredondo, though, again struggled with the Angels and had a 6.53 ERA down the stretch and was ultimately left off the postseason roster.

He pitched in the Dominican Winter League this offseason with Aguilas Cibaenas, throwing 2 2/3 scoreless innings before being shut down last week with discomfort in his elbow.
