If you’re searching for a breakout Rockies relief pitcher this season, he’s not hard to find. Right-hander Carlos Estevez stands 6-foot-6 and tips the scales at more than 270 pounds. A baseball is swallowed up in his huge hand. Add in a 98 mph fastball, 88 mph slider, an occasional 90 mph changeup and a big shot of confidence, and Estevez projects as a key bullpen arm late in games.
