The Marlins are interested in free agent relievers Brad Ziegler and Koji Uehara as fallback options if they’re unable to reel in Kenley Jansen or Aroldis Chapman, according to Joe Frisaro of MLB.com. Miami could sign both Ziegler and Uehara if it loses out on Jansen and Chapman, per Frisaro (Twitter links). Ziegler and Uehara each carry strong track records, though the former is 37 and the latter will turn 42 in April. The pair finished last season in Boston, where Uehara has pitched since 2013. In other Marlins-related bullpen news, the club is “highly unlikely” to re-sign left-hander Mike Dunn, but it continues “monitoring his status,” tweets Clark Spencer of the Miami Herald.
