The Mets hovered around .500 for most of the first half of 2015. A series of trades, however, helped propel the team into playoff contention. Bringing key contributors over from outside of the organization has been the driving factor to their success. Juan Uribe, Kelly Johnson, Tyler Clippard, Yoenis Cespedes, Eric O'Flaherty (okay, maybe not Eric O'Flaherty), and Addison Reed have all become important players for the playoff-bound Mets.
Aside from the Cespedes deal, the Mets' most noteworthy acquisition may have been their last. Addison Reed has perhaps been the team's best relief pitcher since he came over from the Diamondbacks in an August 29 trade.
In 14 games for the Mets, Reed has yet to allow a run. He has allowed only nine hits and four walks (one was intentional) in 13 innings pitched. He holds a 2.07 FIP, so even if a 0.00 ERA is an over-performance, Reed's supporting numbers—strikeout, walk, and home run rates, among others—indicates a stellar run nonetheless.
This has represented a quick turnaround for the 26-year-old. Reed posted a 4.20 ERA with the Diamondbacks. and was demoted to Triple-A in June. He had up-and-down tenures as the closer for both the Diamondbacks and the White Sox, but he appears to have found his niche as the Mets' seventh-inning man.
The Mets bought very low on Reed and have gotten a very high return on investment from him so far. He is under team control through 2017, and could prove to be a valuable asset beyond this season. While it remains to be seen how much the Mets plan to spend this offseason, they'll almost certainly hang on to Reed, especially with Tyler Clippard and Bobby Parnell likely to move on. Reed is making $4.875 million this year and would likely command just north of that in arbitration.
