from the Death Grip category of the A.L. Closer report:
Bobby Jenks, White Sox
Bobby worked just once since we last checked in on the A.L.’s closers, firing two scoreless innings vs. the A’s in a non-save situation on Sept. 9th. Jenks’ secondary stuff has been outstanding in 2009 (+1.91 runs/100 for the slider, +3.45 for the curve), but his fastball hasn’t been as effective. Bobby’s heater was worth +1.55 runs/100 in both 2007 and 2008, but the pitch checks in at -0.47 this year.
