It was just an exhibition, but New York Mets relievers Jeurys Familia, Dellin Betances, and Edwin Diaz all got much-needed work in on Saturday night versus the Yankees at Citi Field.

Some fared better than others, but with Re-Opening Day less than a week away (Friday at 4 PM EST, in case you forgot), game action against another major league team for the first time in over four months is a great thing in any scenario.

Familia entered the game in the top of the sixth, striking out Mike Ford with a disgusting splitter to start his night.

Everyone’s favorite pitching coach, Rob Freidman – aka @PitchingNinja – shared a video of the pitch and just, wow.

Aside from his troubles last season (5.70 ERA, 42 walks in 60 innings), Familia’s splitter was still an elite pitch – when he was able to use it, of course. Used mostly as a two-strike putaway offering, his splitter racked up a measly .235 xwOBA and 34% whiff rate. That’s a bonafide weapon.

Despite two Yanks reaching on two separate throwing errors courtesy of Max Moroff, Familia induced two ground outs via Miguel Andujar (scored a run) and Clint Frazier to limit the damage.

After retiring Tyler Wade and Kyle Higashioka (his second strikeout), left-hander Justin Wilson set down Mike Tauchman on a fly ball to left to end the frame.

Familia told the Mets press corps he felt good at a lower weight after partaking in a rigorous offseason training program, adding his delivery felt “smoother” and “I’m able to locate my pitches the way that I want.”

That’s a promising development.

Down 4-2 but still in the game and very much in need of a clean inning, Mets skipper Luis Rojas turned to still-yet-to-debut Mets right-hander Dellin Betances.

The 32-year-old – signed to a one-year deal with player options for 2021 and 2022 – worked around a leadoff single via Gleyber Torres to close out his former teammates. Reports had Betances sitting 92-93 with his fastball, a great sign after velocity concerns in the spring.

After the game, Betances told reporters he “felt good” after pitching in consecutive games, adding, “My [velocity] is actually better than I would have thought to be honest with you, so I’m happy about that.”

We’ll take what we can get. Let’s hope he’s ramped up by next weekend.

Edwin Diaz, the maligned right-hander coming off a putrid 2019, entered in the ninth with that same 4-2 deficit staring at him, but performed well, all things considered.

Matt Duffy reached on a rare fielding error via Luis Guillorme to start the frame and Andujar singled on a mix-up between Guillorme and right-fielder Jarrett Parker in shallow right field, signifying more of the same for the 26-year-old flamethrower.

Diaz recovered to get former top prospect Zack Granite swinging for the first out of the ninth and was replaced by Daniel Zamora. All in all, Diaz played his game – induce weak contact and get swings and misses.

“Today I was primarily using my fastball because I didn’t feel the hitters had a chance,” Diaz told reporters after the game. “I felt a lot of the contact they were making was weak so why would I go away and slow my pitches down when they couldn’t catch up?”

Gotta love a logical approach. The Mets head to the Bronx to finish off their home-and-home exhibition on Sunday night at 7 PM EST.
