The Mets plan to meet with agents for free agent relievers John Axford and Kevin Gregg. As well as them, the team has also been linked to Chris Perez and Mitchell Boggs.
Axford, 30, split the 2013 season with Milwaukee and St. Louis, posting a combined 4.02 ERA in 75 relief appearances. He played significantly better in his brief stint with the Cardinals, as he had a 1.74 ERA in 13 games.
From 2010-2012, the right-hander was known as one of the more dominant closers in the game, putting up a 3.04 ERA during that time while notching 105 saves. There have been some criticisms over his control, as he does sport a 4.0 BB/9 ratio, but his strong strikeout numbers (career 10.8 K/9) tend to overshadow that.
Gregg, an 11 year veteran, spent the entire 2013 season with the Cubs organization, and had a solid comeback season. The 35 year old had a 3.48 ERA in 62 relief appearances, while racking up 33 saves and finishing 52 games.
He put up similar numbers back in his prime with the Marlins from 2007-2008. During that time, he posted a 3.48 ERA with 61 saves in 146 relief appearances.
The Mets are clearly concerned about Bobby Parnell heading into the 2014 season. As you recall, he underwent neck surgery that ended his 2013 season a little early, but it was expected that he would be ready for Opening Day of this coming season.
To me, Axford is the more appealing option, simply because of his track record. Not too long ago he was one of the best closers in the game for the Brewers, but after a year and a half of so-so numbers, he was dealt to the Cardinals and seemed to rediscover himself. I would take him on an incentive-based deal, and give him the opportunity to close some games if Parnell isn't ready.
Of-course, it's worth mentioning that Vic Black will be in the running for some sort of late-inning role for the Mets next year. Bringing in a veteran like Axford, Gregg, etc., could prove to help Black out quite a bit in his development.
