I really hope this move sticks. I've had Hen for a while now, and I desperately need another closer. I'm in a holds league and I have 5 guys who are next in line if a closer fails (Hennessey, Scot Sheilds, Linebrink, Betancourt, Okajima), but only 2 closers since BJ Ryan went down. I've been standing pat, assuming that one of these guys will get a chance eventually (meanwhile, my team is in a dreadful slump, but at least I'm cleaning up in holds).
So, go Hennessey!
