It certainly has been a good start for the top Cubs minor league pitchers. Butler (even thought he won't count towards the system's ranking is still important), Clifton, De La Cruz, Hatch and Cease combined for 24.2 IP, 17 H, 4 R, 3 ER, 11 BB, 25 K for a 1.09 ERA and a 1.14 WHIP. Lesser prospects Zastryzny, P. Johnson, Tseng, Alzolay, T. Miller and Rondon threw 24.1 IP, 15 H, 5 R, 5 ER, 6 BB, 32 K for a 1.85 ERA and a 0.86 WHIP. Add in bats like Jimenez, Happ, Candelario, Caratini with some emerging bats like EJM, Parades, etc., Albertos once short season gets started and the 27th and 30th draft picks and this system could be pretty solid by year's end. It will be fun to track for sure.
