Johan Santana injury: Mets LHP undergoes surgery

New York Mets left-handed starting pitcher Johan Santana underwent successful surgery this morning to repair a torn left shoulder capsule, according to Anthony DiComo of MLB.com.

Santana was diagnosed with a tear in his shoulder last week, a similar injury to the one that caused him to miss the entire 2011 season. Following today's successful procedure, the left-hander will be sidelined for the entire 2013 campaign. There was initially speculation that Santana could call it a career, but it's since come out that he'll attempt to make a comeback and return to the majors.

Rangers extend Andrus

The Rangers and shortstop Elvis Andrus agreed on an eight-year, $120 million contract extension.

The news got worse for the Mets when it was reported that the team hand't insured Santana's remaining contract. Rather than pay a premium on the veteran, New York elected to self-insure against injury. This will result in the team being on the hook for the entire $31 million he's still owed -- $25.5 million this year and a $5.5 million buyout for 2014.

Over a year removed from his first significant shoulder surgery, Santana made 21 starts for the Mets last season. The 34-year-old maintained an ERA of 4.85 over 117 innings with a strikeout-to-walk ratio (SO/BB) of 2.85. From 2000-10 -- prior to surgery -- Santana posted an ERA of 3.10 with 3.55 SO/BB.
