Sportsfan, you see what Stammen is doing against Bowie [7.0 IP, 3 H, 7 SO]; He has 32 IP @ Harrisburg thus far with 6 ER, 16 H, 10 BB, and 18 SO.
Yes, I was just about to post on that. He is officially on everyone's radar now.
Look at his starts since being promoted to AA:
6.1 IP 2 ER
7 IP 2 ER
5 IP 1 ER
7 IP 1 ER
And then tonight 7 IP 0 ER so far
