Wade Davis’ repertoire is devastatingly effective. The Rockies’ new $52 million closer can grip it and rip it when he needs to because his 95 mph four-seam fastball generates plenty of swings and misses. His 91-93 mph cutter, with its deceptive, late-breaking action, leaves frustrated batters shaking their heads. His 83 mph breaking ball, thrown with a knuckle-curve grip, buckles knees. All of that has made Davis one of baseball’s premier relievers.
