Castillo could be in line for a promotion to Triple-A Louisville soon, C. Trent Rosecrans from the Cincinnati Enquirer reports. He has a 2.08 ERA, 0.90 WHIP and 25:4 K:BB at Double-A Pensacola in 30.1 innings so far.

EDGE Analysis

Castillo, acquired in the Dan Straily trade, really impressed teammate Devin Mesoraco when Mesoraco did his rehab stint with Pensacola. "Castillo is almost equally impressive," said Mesoraco, who caught two of Castillo's starts for the Blue Wahoos. "(He has) really good plus stuff, obviously, but he throws so many strikes. He throws a lot, a lot of strikes with all three pitches."
