Minor-league K:BB leaders

So, I got curious - who in the minor-league system is posting K:BB ratios over 3.5 (arbitrary, I know)? Let's look across the full-season leagues, shall we? (Minimum 30IP):

Name	Team	IP	K	BB	K:BB
Ballew*	LAN	36.2	59	10	5.90
West*	LAN	74.1	75	13	5.77
Buchanan	CC/OKC	106	68	14	4.86
Rodgers	LAN/OKC	92.1	77	17	4.53
Jankowski	QC	85.1	76	17	4.47
Dimock	QC/LAN	34	31	7	4.43
Sanchez*	QC	42.2	49	12	4.08
D. Martinez	CC	104.2	66	17	3.88
Hauschild	QC	83.1	59	16	3.69
Velasquez*	QC	91	102	28	3.64

(Asterisks indicate K/9 ratio over 10.0)
