The Phillies are planning to call up Scott Mathieson to start Saturday against the Devil Rays.
The 22-year-old Mathieson is 6-2 with a 3.05 ERA, 67 H and 95/26 K/BB in 85 2/3 IP for Double-A Reading. He’s a very good prospect, but he’s probably not ready just yet. At best, he’s worthy of a bench spot in NL-only leagues. Should he get off to a good start, he could keep a rotation spot after Jon Lieber returns, with Ryan Madson perhaps returning to the pen.
