In response to patrickford's comment:
I like RDLR as an option as well. Closing is a "make-up" issue. It's even more a "make-up" issue in Boston. It's been shown there are guys who just can not play in Boston. The pressure caves them. Sadly Bailey has proven to be that kind of player.
Uehara is not an option. He's not durable enough.
Tazawa looked a bit suspect when he tried to close.
I might be inclined to give Aceves another shot.
It wouldn't hurt to roll RDLR out there. I never felt a player acquired a closers mentality, or the kind of mental make-up needed to perform under pressure.
RDLR is on an innings limit this year and is bound to be shut down at some point. His innings could be limited and stretched out in a bullpen role but could still poise problems down the road and into the playoffs.
Also you are talking about a potential top of the rotation starter who you are trying to groom into a starting role, I don't think taking him in a recovery season and say "hey instead of trying to increase your innings a little bit every start, just go out there every day and throw as hard as you can for 15 pitches"
It works....but it also doesn't work. You don't know how the TJ recovering starter in the minors is going to do closing in the majors.
I say we try closer by committee for the next month and if we find someone who sticks (and that may be Bailey if he can recover then so be it) but if we can't....then I think the orginization looks to trade for a closer.
