The Reds announced today that left-hander has been placed on the 15-day injured list due to a left flexor strain, retroactive to June 17th. Right-hander has been recalled to take his place on the active roster. Righty has also been added to the taxi squad. reported on the Phillips promotion earlier today. Miley was the scheduled starter for Saturdays game but that Petty will now be making that start. The club has not yet provided any information about the severity of Mileys injury but its an unnerving development. Its always concerning when a pitchers throwing arm is injured and that Al Horford Jersey s especially true in this case. The 38-year-old Miley underwent Tommy John surgery in April of last year and only recently returned to the mound with seven minor league starts and three major league appearances. Time will tell if this injury is significant or not, but either way, the Reds rotation will take another hit for at least a few weeks. They already have , and a few other arms on the IL and now Miley joins them. Mileys injury leaves , , and in four rotation spots. It seems Phillips will provide an extra arm for todays game but he may get optioned back down tomorrow to make way for Petty. Petty, 22, is one of the top pitching prospects in baseball. The Reds have called him up twice this year to make spot starts without good results. He has allowed 13 earned runs in 5 1/3 big league innings thus far. He has spent the rest of the year pitching in Triple-A with a 2.76 earned run average. His 26.9% strikeout rate is quite good but his 11.4% walk rate is on the high side. Its unclear if Petty is going to stick in the rotation or if this is another spot start. Prospect is currently dominating Triple-A hitters through two starts at that level. Hes not on the 40-man roster but could perhaps get a call soon. Photo courtesy of Ken Blaze, Imagn Images Chris Paul Jersey
