As the trade deadline approaches, Jim Henderson and Rex Brothers have emerged as my two favorite would-be closers, assuming Francisco Rodriguez and Rafael Betancourt are dealt. But John Axford is pretty high on the list.
I can't see him closing for the Brewers again, particularly since they're reportedly motivated to hold on to Henderson. But since losing the role in early April, Axford has a 1.80 ERA, 1.26 WHIP and 9.3 strikeouts per nine innings.
He's still erratic, but with his hard fastball and closing experience, he may turn out to be every contender's second choice (behind Rodriguez) if the Rockies decide they're close enough to contention to hold on to Betancourt.
In a 24-team dynasty league, I'm sticking with Axford just for that reason. It's kind of a longshot, but in a league that deep, it's my best chance to get a closer for cheap.
