Whitlock (elbow) resumed throwing Wednesday and is expected to throw a bullpen session in the near future, Tim Healey of The Boston Globe reports.
Whitlock was placed on the 15-day injured list with right elbow inflammation last week but appears to be nearing a return to the mound. It sounds like Whitlock's stay on the IL could be around the minimum. The 30-year-old has posted a 2.05 ERA, 0.89 WHIP and 49:7 K:BB across 44 innings out of the Boston bullpen this season.
