Vizcaino hit 98 mph with his fastball while striking out two in an inning of work during Friday's Grapefruit League game against the Red Sox, The Atlanta Journal-Constitution reports.
He did give up a solo home run to Andrew Benintendi, but otherwise it's been a great start to the spring for Vizcaino, who's whiffed five batters in his first two appearances. The shoulder injury that derailed his second half last year doesn't appear to be an issue for him heading into 2017, and Vizcaino should begin the season as the Braves' primary setup man.
