Swarzak Good But Not Final Piece For 2018 Mets Bullpen
After the purported hand-wringing Sandy Alderson was doing over the free agent reliever market, the Mets finally pulled the trigger, and they signed Anthony Swarzak to a two year $14 million deal.
There is a lot to like about Swarzak. Last year, the 32 year old had his best ever season going 6-4 with a 2.33 ERA, 1.034 WHIP, 2.6 BB/9, and a 10.6 K/9. As noted by D.J. Short of Rotoworld, Swarzak had a higher swinging strike percentage than old friend Addison Reed. Part of that could be attributed to the fact he added about two MPH on his fastball.
He’s also been a platoon neutral pitcher his entire career with his best season being in 2017. While limiting right-handed batters to a .218/.259/.346 batting line, left-handed batters were worse against him hitting .198/.294/.281.
These stats are all the more incredible and important when you consider he predominantly worked in the 7th and 8th innings. The Mets needed another set-up man to work with AJ Ramos to hand the ball to Jeurys Familia in the 9th.
Overall, this is all important, and the signing helps the Mets. However it isn’t enough, especially because this is all but a shapshot of Swarzak’s career.
It was just in 2015 Swarzak had a 5.26 ERA and 1.516 WHIP in the Korean Leagues. In 2016, his first season back from Korea, he was 1-2 with a 5.52 ERA for the Yankees.
While he was obviously improved since then, it was mostly on the strength of some outliers. Prior to last season, he yielded a .304 BABIP. In 2017, that number was .272.
Prior to 2017, Swarzak left 69.8% of runners on base, which is right around league average. Last season, his LOB% was a career best 82.9%.
Maybe these numbers were all the result of improved stuff. Maybe it was him becoming more comfortable in the bullpen. It’s just as possible the increased velocity and some of the BABIP and LOB% will regress to league and career norms.
Overall, the Mets did acquire a quality reliever who should prove to better than internal options like Hansel Robles, Paul Sewald, and Josh Smoker. Moreover, Swarzak is getting the opportunity to work with Mickey Callaway and Dave Eiland. If there’s a tandem you trust to help Swarzak make 2017 the new norm instead of an outlier, it’s them.
Still, with the stark contrast between the 2017 and career numbers, the Mets need to hedge their bets that Swarzak may very well regress. In the end, this means that while Swarzak may very well prove to be a nice addition, he’s far from being the final piece of the puzzle.
