Mets pitcher Sean Manaea, rehabbing from an oblique injury sustained during spring training, was recently diagnosed with a loose body in his left elbow, but the team doesn't believe the discovery should delay his return for long.

New York Mets starting pitcher Sean Manaea hit a big milestone in his recovery from an elbow injury that put him on the injured list.

The lefty complained of elbow soreness after his last rehab start Friday and received an MRI and cortisone shot Monday. Manaea felt discomfort toward the end of a start where he allowed one run over 5 1/3 innings, with seven strikeouts, and didn't recover the next day as he expected.
