He claimed the reason he passed on the WBC in the past is that he wouldn't be effective. He didn't think he would be ready in Spring Training to compete at a high level.
So it's quite ironic he thought he could be effective four years into retirement. Canada Baseball didn't beg him. He called them and said he wanted to do it. Same with Gagne.
Canada Baseball really f***es up having him start 2 of the 3 games. It goes beyond comprehension.
