Team: Durham Bulls (Tampa Bay Rays)
Season stats: 4-3, 1.44 ERA, 11 saves, 104 strikeouts, 15 walks, 43 appearances (62 1/3 innings)
After starting the season by not allowing an earned run in 16 innings at Low-A Charleston, along with recording 36 strikeouts and one walk, Colby White was promoted to High-A Bowling Green. Continued dominance led to two additional promotions as White landed at Triple-A Durham after hitting all four full-season affiliates without posting an ERA above 2.35 at any stop.
