Montero threw two perfect innings of relief in Monday's Grapefruit League game against the Astros, striking out four.
He's now struck out six batters over four shutout innings to begin his spring. Montero's role is still uncertain heading into the 2017 season, and indeed there's no guarantee he's even on the Opening Day 25-man roster, but if he continues pitching like this he could force his way into the fifth starter battle between Robert Gsellman and Seth Lugo.
