He's been a decent arm for the last two years for Toronto. A guy who can get righties out, throw multiple innings, go through a lineup once (unless it's too lefthanded - lefties crush him).
He's out of options too so he'll almost certainly be the #7 RP out of the gate, unless he gets hurt or traded before opening day.
He's a sinker/slider guy who only sits ~90 and doesn't even get groundballs though. Could be terrible at any given point.
