A team this putrid on offense, can't punt an OF position for defense over offense. Gavin is good enough, for now, until the organization gets its head out of its ass and realizes Colas is the right option. This team is proving it right now, you can't set up your offense with 3 automatic outs at the bottom of the order, when the top 6 have their own share of problems.
Haesley has no business starting a MLB game, ever. If it is because Gavin is hurting after the slide yesterday, then sure. But normally, Haesley is about as useful as Romy Gonzalez, and that isn't a compliment.
