Baseball Prospectus.com reviews Aroldis Chapman’s professional debut this week:

Aroldis Chapman, LHP, Reds (Triple-A Louisville)

While the best pitching prospect in baseball was making his professional debut in Altoona, the best left-handed prospect in the game was in equally glamorous Toledo, putting the first numbers on his official record. Chapman had better overall numbers than (Stephen) Strasburg, and he was throwing a bit harder as well, getting up to triple digits with his fastball and dominating primarily off of that while also flashing a solid slider. For a guy who has had occasional control issues, that certainly wasn’t the case on Sunday, and if that remains the case, he could beat Strasburg to the big leagues.
