Already this season, New York Yankees starter Bartolo Colon has thrown more Major League innings than the last two years combined, and has already had his most successful season on the mound since 2005. Yesterday, on Memorial Day, Colon went out and threw a complete game shutout against the Oakland Athletics, giving up only four hits, no walks, allowing just seven balls out of the infield, while striking out six on just 103 pitches.

Much has been made of the stem cell treatment that Colon received prior to this season, as it gets the credit for transforming Colon and the declining velocity of his fastball from an old pitcher on his way out to a guy taking full advantage of his opportunity to get one last kick of the can. However, as Dave Cameron pointed out for FanGraphs a couple of weeks ago, there are some numbers that indicate that his rebound isn’t that surprising and that it may not be sustainable.

Even without the miraculous stem cell treatment, it would be fair to expect Colon’s velocity to get back to where it was before 2009. He rested the arm for most of 2010, and like most pitchers who are forced to take a year off because of an arm injury, he’s returned throwing harder than he was before it.

As for the sustainability of his numbers, the usual tell tale signs like BABIP and LOB% are fairly close to the league average, with Colon’s BABIP slightly lower and LOB% slightly higher, but if you look at his recent swinging strike rate of 6.0 (the seventh worst among starters in the American League), we find that he’s far below the league average of 8.4. His overall strikeout rate has been one of his keys to success and the low swinging strikes indicate that he might not be able to continue gathering Ks at a rate above the league average and his career norms.

Colon’s swinging strike rate is so low that it’s going to be nearly impossible for him to maintain this kind of strikeout rate going forward. Whether he’s just been the beneficiary of some friendly strike zones or batters are so surprised that he’s throwing strikes that they forgot to swing does not really matter all that much – we have to expect that Colon won’t keep freezing hitters at the rate he has been, and his strikeout rate will probably return to something closer to his previously established norms.

Colon, despite his pleasant scent, is going to be battling a two front war in the coming months of the season. Not only has the pitcher not thrown over 100 Major League innings since 2005, and there’s a safe expectation that he’ll eventually fatigue, but that mean old regression host is waiting in the wings to haunt Colon’s revival season. But that’s not going to stop Yankees fans from enjoying everything that they can get out of an offseason reclamation project, that for once, has actually worked out well.
