Sunday was a day full of news for three young pitchers in White Sox camp. The oldest of the news-making trio, Carlos Rodon, threw his second bullpen session. He threw 35 pitches (and felt, presumably, much better than while throwing his first bullpen of the year) and seemed to focus on the changeup. Rodon will throw his first live batting practice on Wednesday and could make his Cactus League debut as soon as March 13th against the Indians. The White Sox maintain that the schedule for Rodon has him on track to make a start in the first time through the rotation.

The youngest of the three pitchers, Michael Kopech, was slated to work against the Diamondbacks on Sunday but had his work rescheduled for Tuesday. Kopech, who gave up four earned in one inning of work in his first start, will throw 3 innings in a simulated game. The idea is to control the conditions of Kopech’s outing and allow him to work on specific pitches in addition to getting stretched out more. The move doesn’t shift the high expectations the Sox have for Kopech as he’s still one of the brightest stars in the system. Still, the plan was always for him to start in the minors–perhaps AA or even high A.

The middle child, Reynaldo Lopez, debut his electric stuff and improving command in three innings of one run ball against he Diamondbacks Sunday. Lopez was a bit wild in the first inning and gave up two doubles and a run but finished the day throwing more strikes with the fastball in the second and third innings. He also struck out Paul Goldschmidt, one of the of the best hitters in the game, twice–one looking, one swinging.

All in all, good news for the young White Sox pitchers as the young Spring gets just a little older.
