Ryan McNeil has quietly gotten interesting. 3rd round pick from the Blackburn/Underwood draft, had the surgery. Came back last year and had 8.4 ERA at Boise. Started wild and slow this season, but overall he's now at 2.73 ERA in 53 innings, with 49K/20BB/2HR/53IP, and 19K/6BB/19IP over last 10 games.
I imagine the injury is enough behind now that he can focus on pitching and getting outs.
Could be interesting to see how he gets used next year, and whether he steps it up.
