An MRI on Polanco's left ankle/Achilles tendon came back negative Tuesday, Andrew Tredinnick of The Bergen Record reports.
Polanco has battled problems with his Achilles all season, and the Mets paused his rehab assignment Saturday due to renewed soreness in his left ankle. Now that the 32-year-old has been cleared of any structural damage, the Mets will look to have him resume batting practice within the next few days.
