Los Angeles Angels left-hander Brandon Sisk is expected to undergo season-ending Tommy John surgery within the next couple of weeks, according to Alden Gonzalez of MLB.com.

Gonzalez notes that Sisk entered spring training with a "tender" elbow. The 27-year-old made only two one-inning appearances before being sent down to minor league camp after it was discovered that he would require surgery. He allowed one run on one hit with no strikeouts or walks over two innings this exhibition season.
Los Angeles acquired Sisk from the Royals this offseason in the trade that sent right-hander Ervin Santana to Kansas City. The Angels placed the southpaw on the 40-man roster in December in order to protect him from being selected in the Rule 5 Draft, showing they at least think something of him.
Sisk spent the 2012 season with the Royals' Triple-A affiliate. Over 50 appearances --spanning 67 1/3 innings -- the left-hander maintained an ERA of 2.54 with a strikeout-to-walk ratio (SO/BB) of 2.28. Over parts of five seasons in the minors, he owns a career ERA of 2.59 with 2.79 SO/BB.
