…no, we’re not talking about the traditional garb of Red Sox fans. We’re talking about Ben Sheets. He’s attempting a comeback, and apparently auditioned last week for four teams, including the Yankees.

Cashman should be all in on this guy. He’s obviously a huge risk — he’s been out of baseball since 2010 and has the health record of 60-year old hooker in Bangkok. But that risk is going to mean his price will be incredibly cheap relative to his upside. No one thinks he’s going to revert to his 2004 self — though it’s notable that he had such a season, a level which few other pitchers in history have achieved (2.76 xFIP over 237 IP, 8.0 WAR, 62 xFIP-). His last mostly healthy season was 2008, where he put up a 3.88 xFIP over 198 innings. If he’s healthy, he’s a solidly above average pitcher with an intriguing and demonstrable upside. Obviously, it’s a huge if.

Can he come back effective at this point? After all, this is a once great pitcher that has been beaten down by injury, is now 33, and who we last saw putting up a nothing-to-write-home about 4.27 xFIP (102 xFIP-) in 2010.

There is a very recent precedence. Johan Santana, a once great pitcher, is now 33. He missed all of 2011 after undergoing surgery on his throwing arm, and is currently having an ace level season that would be a nice addition to any team in MLB.

Sheets could possibly add another dominant arm to the Yankees bullpen, which will be huge come playoff time. He might also serve as a pretty good insurance plan should one of the Yankees’ starters succumb to injury.

Why not?
