The Yankees have enough experiments going on, they don’t need to change Chad Green’s role. In any way. Don’t mess with success. Leave him as the dominating bridge right-hander in the bullpen. Green owns a rising fastball that works wonders in this Launch Angle Era. The great thing is Green has totally embraced his bullpen role. Sure, down the road, he would not mind going back to being a starter, but for now, the Yankees are at their best with Green in his lockdown role in the bullpen. Green made his second start of the spring Sunday, firing two scoreless innings in a 9-1 loss to the Rays at Steinbrenner Field, striking out four. This does not need to be turned into a Joba Chamberlain situation. Should he relieve or should he start? Let Green continue to work his magic in his specific bullpen role until he fully develops his changeup. There’s a lot going on here at Yankees camp. There is the Great Aaron Boone Experiment. Can he dive from the broadcast booth to managing even though he has never managed before? There is the Great Left Field Experiment.
