6:05pm: Nick Peruffo reports Heathcott is heading to the team’s complex in Tampa and will have an MRI. He says it sounds like the outfielder is done for the year. The minor league season ends in less than three weeks anyway.
5:00pm: Via Mike Ashmore: OF Slade Heathcott has been placed on the Double-A Trenton DL with with right knee tendinopathy, which, from what I understand, is damage to the tendon without the typical inflammation that comes with tendinitis. No word on how long the team’s third best prospect will be sidelined. The 22-year-old Heathcott has a long injury history, mostly involving his twice surgically repaired left shoulder. He’s hit .261/.327/.411 (103 wRC+) with eight homers and 15 steals in a career-high (by far) 444 plate appearances for the Thunder, including a .283/.355/.448 line over his last 60 games.
In other minor league injury news, RHP Mark Montgomery has been placed on the Triple-A Scranton DL according to Donnie Collins. He left Saturday’s game with a shoulder issue and I assume the DL stint is related. If so, this is his third shoulder-related DL trip of the season. Montgomery, 22, has a 3.38 ERA (4.00 FIP) in 40 Triple-A innings with an excellent strikeout rate (11.03 K/9 and 28.0 K%) that is actually well below what he had done in previous years (14.56 K/9 and 40.0 K% from 2011-12). His control has completely deteriorated this summer (5.63 BB/9 and 14.3 BB%). I ranked Montgomery as the the team’s 17th best prospect in my latest update. Had he been healthy and productive this year, chances are he would have been in the big leagues already.
