Winter is here for Martin Prado, Wei-Yin Chen and Nick Wittgren. With days remaining in the Miami Marlins’ season, those three won’t play again in 2017. Prado had held out hope that he would make an on-field cameo this week, but he has simply run out of time rehabilitating his right knee, he said. Chen is again experiencing left elbow discomfort, and he’ll visit Los Angeles-based Dr. Neal ElAttrache in the coming days, manager Don Mattingly said. Wittgren had surgery Tuesday to remove a bone chip from his right elbow. The Marlins expect him to be ready for spring training. Chen’s news Tuesday came as the most surprising. He missed two months last season and four months this season with ongoing left elbow issues. He told the Sun Sentinel in April, before this year’s recurrence of the problem, he has a partially torn ulnar collateral ligament in his left elbow.
