The Orioles' 2010 Minor League Player of the Year, Double-A Bowie first baseman Joe Mahoney, is expected to miss the next three to four weeks with a quadriceps strain. Mahoney is making his second trip to the disabled list this year for the same injury.
Mahoney was out earlier from April 10-25, and returned to game action, but so did the quad injury, and he underwent an MRI yesterday. Mahoney is expected to report soon to the Orioles' spring home in Sarasota to continue his rehab.
Mahoney was batting .235 in 10 games with Bowie.
Meanwhile, right-handed pitcher Ryan O'Shea of the Single-A Frederick Keys is also on the disabled list. He felt some tightness in his shoulder and had one start skipped. He could be back on the mound in three to four days.
O'Shea is off to a very good start at 2-1 and his ERA of 1.99 is third-best in the Carolina League. Over 22 2/3 innings, he has fanned 14 and pitched to an average against of .244. He has allowed two runs or fewer in each of his starts.
