Several veteran Yankees had surprising seasons in 2015. Can the team withstand regression to the mean?
In many ways, 2015 was a wonderful season for the Yankees. Fans were understandably dissatisfied with merely hosting a wild card game, but the team did win its most games since 2012. Not only that, but New York also posted better underlying numbers in the form of their best Pythagorean and BaseRuns records of the past three years. The team managed a notable improvement despite uncharacteristic financial restraint (or perhaps frugality) from management. The improvement was propelled by resurgent seasons from a number of players well past their primes, namely Mark Teixeira, Carlos Beltran, and Alex Rodriguez.
