One of Bobby Cox's signature strengths was his ability to take pitchers of limited reputation and track record and assemble them into superior bullpens. In Fredi Gonzalez's first season as manager, he'll have to do the same to keep the Braves within shouting distance of the Phillies—and his decision late in camp to use second-year lefty Jonny Venters and rookie righty Craig Kimbrel as co-closers was an encouraging sign. Gonzalez can exploit the fact that he has two quality arms to work with and use them as situations warrant. Venters's fastball-slider repertoire generated ground balls on more than two thirds of balls in play last year, and there wasn't much difference between his numbers against lefthanded and righthanded hitters, so he can be trusted to face tough hitters on both sides. Kimbrel is a fireballer who collects both walks and strikeouts in high numbers and is extremely difficult to hit. Let's hope Gonzalez has the courage to stick with the co-closers plan even if Venters and Kimbrel hit early-season rough spots. The tandem could give him a versatile bullpen reminiscent of the Reds' Nasty Boys in 1990.
