It is imperative the Mets get Jon Niese in a couple of games in this weekend, preferably in back-to-back outings, as the lefty bullpen specialist remains an issue. However, a poor weather forecast might prevent that from happening.
Although volunteering to go into the bullpen was admirable, Niese was not effective in two outings in Philadelphia against left-handed hitters (he gave up four hits against five hitters).

Overall this season lefty batters are hitting .297 against him with a .335 on-base percentage. Those aren’t numbers conducive to being a lefty specialist.
If you’re wondering about swapping Niese for Bartolo Colon in the rotation (assuming Steven Matz is left off for the NLDS), his numbers against lefties are a .290 average with a .309 on-base percentage, so that’s not practical.
A mitigating factor towards making this decision is the ability of each to get loose quickly. Niese knew when he would enter the game and given ample time to get ready.
However, neither he nor Colon could have that advantage in the playoffs. As of now, Colon seems slated for the rotation with Matz sidelined with a stiff lower back. The Mets want to get Matz work this weekend, but the weather might prevent that from happening. As a last resort, the Mets could send him to Port St. Lucie.
With Niese not working out, it might be tempting for manager Terry Collins to consider Tyler Clippard in that role as lefty batters are hitting just .138 against him. However, if Collins uses him in that role, what would it mean to the overall set-up of the bullpen regarding the set-up role?
They could explore Clippard against lefties and use Addison Reed in the set-up role, but changing roles on the fly is always tricky. Even so, the Mets must have separate concerns with Clippard, who has given up eight runs in his last ten appearances (ten innings).
Speaking of changing roles, there’s Sean Gilmartin. He’ll likely make the playoff roster if Matz can’t go. He was effective today, giving up two runs in five innings. This year, lefties are hitting .272 against him, but he hasn’t been showcased as a specialist.
A intriguing possibility is Hansel Robles, who has given up 13 hits in 78 plate appearances to lefty hitters (.167 average with a .214 on-base percentage). Dario Alvarez is getting a look-see, but his window (six appearances, including today) is too small.
This concern is primarily based on a potential late-inning match-up against Adrian Gonzalez (28 homers and 88 RBI). Of course, they could go the route the Angels took against the Giants’ Barry Bonds in the 2002 World Series and just intentionally walk him.
