Yes!
Stephen Kahn, last seen pitching meaningful innings in 2006, is with High Desert and pitched two scoreless frames last night. Apparently he pitched one inning in AZ rookie ball in 2009 and disappeared again until returning with a couple of wobbly innings on June 9 of this year.
Kahn blew through the Cal League with a 1.95 ERA and 11.4 K/9 in early '06 before disappearing into the mist.
