Mets manager Carlos Mendoza spoke about the offensive production from Brett Baty and Mark Vientos at first base, saying: "Obviously we expect more." Mendoza also spoke about the decision to start David Peterson against the Nationals.

Brett Baty found himself on the wrong side of an ABS reversal twist of fate as the Mets are swept by the Rockies.

A frustrating season continues for the New York Mets as they fell 1-3 against the Colorado Rockies in a doubleheader opener on Sunday. But beyond the results, one moment took most of the attention.

Done in by a robot reversal, Brett Baty of the New York Mets became the first batter to have a bases-loaded walk changed to an inning-ending called third strike by Major League Baseball's new challenge system. Plate umpire Ryan Blakney was challenged four times in the first inning of the Colorado Rockies' 3-1 win a in doubleheader opener on Sunday, and three calls were overturned. Baty dropped his bat and started to take off his batting gloves as he headed toward first after Blakney called ball four on a bases-loaded, full-count sinker on the outside corner.

The Mets’ third baseman was called out on strikes on a pitch that caught the bottom of the strike zone and tossed his bat in frustration as he walked out of the batter’s box.

It sure seemed like Ryan Blakney was looking for a confrontation.

The Mets and Rockies play a doubleheader at Citi Field on Sunday, but before the games began manager Carlos Mendoza provided a few updates on Brett Baty and Jorge Polanco.

Brett Baty has been slumping offensively, and on Friday, he hurt the Mets with his defense too.

During the Friday afternoon game in Chicago, the Mets had a disastrous inning, led by Brett Baty, not being able to handle first base.
