NL East Notes: Dunn, deGrom, Winkler, Nationals

Marlins left-hander Mike Dunn has had a setback in his recovery from tightness in his left forearm, writes MLB.com’s Joe Frisaro. The Marlins are bracing themselves to be without Dunn — their most reliable reliever across the past five seasons — for longer than they initially expected. “He didn’t come out very good from his ’[bullpen session],” manager Don Mattingly said. “He felt a little grab in there again. So, we’re going to slow him down, and I think he’s going to talk with [team physician Dr. Lee Kaplan] again and see where it goes.” As Frisaro writes, the initial MRI on Dunn didn’t reveal any structural damage, but there’s no timetable for his return at the moment until he has the injury reexamined. Dunn, 31 in May, has posted a 3.62 ERA with 10.1 K/9 and 4.4 BB/9 in 285 2/3 innings with the Marlins. He’s set to become a free agent at season’s end.

• The Mets are bracing for the possibility that Jacob deGrom will require a stint on the disabled list, writes MLB.com’s Anthony DiComo. That possibility, DiComo writes, is the reason that New York didn’t place deGrom on the paternity list for the birth of his son. Had deGrom gone on the paternity list, the Mets would’ve given up the ability to backdate a DL stint to the date of his most recent start. As such, if deGrom is placed on the disabled list, the move could be made retroactive to April 9.
• Braves right-hander Daniel Winkler, who fractured his right elbow over the weekend, will see Dr. James Andrews tomorrow, tweets Mark Bowman of MLB.com. Bowman notes that the early indication is that Winkler’s surgically repaired ulnar collateral ligament was not damaged in the injury, though he’ll meet with the renowned Dr. Andrews to ascertain that fact. Even if his UCL is intact, Winkler seems likely to be facing another prolonged absence in the wake of the new injury.
• The Nationals’ hiring of Davey Lopes has already begun to pay dividends, writes James Wagner of the Washington Post. New manager Dusty Baker came to the Nats with the goal of making the club more aggressive on the basepaths and improving the club’s stolen base numbers and overall running efficiency. Lopes has already been working with Bryce Harper to improve his stolen base acumen in an effort to punish opponents who pitch around him. “There’s something you can take advantage of [every opponent],” Baker tells Wagner. “And Davey Lopes is the best at picking that up. He’s the best. Davey sees things that very few people see [in] the young players. He’s been around a long time. He was one of the best at his craft when he was playing. So coaching does come into play.”
