OAKLAND, Calif. — When Luke Weaver arrived to the Yankees last September, they could not have seen this coming.

Turning into a closer and delivering in the biggest moments late in meaningful games? No, not that (but not that either).

When the Yankees claimed the then-starter off the waiver wire last year, they had no idea about the character that is Luke Weaver.

“Nothing I would have ever expected,” said Tommy Kahnle, the resident character of the bullpen in a much louder way.
