3) Mets roster will not have Travis Jankowski on it after the trade deadline
Travis Jankowski has been a fun addition to this Mets team. He brings speed and defense and is fun to watch in my opinion. However, he simply cannot hit. When the Mets were in Atlanta without Jeff McNeil and Starling Marte, Jankowski had to play every day and he was hitless in eight at-bats.
Jankowski fits the profile of the other fourth outfielders the Mets have rostered in the last couple of years like Juan Lagares, Keon Broxton, and Jake Marisnick to name a few. All glove, no bat.
With the Mets getting virtually nothing from their catcher and DH spots offensively, they need more from this roster spot even as a backup. The Mets can find an outfielder with speed who can play defense and can also hit at a relatively league-average level.
Jankowski has just nine hits in 54 at-bats and no hits in his last 29 at-bats dating back to May 2nd. He has a -0.1 WAR despite most of his appearances coming as a defensive replacement or pinch runner.
The Mets have done very well when he's appeared in games, but that's mainly because he comes in for the ninth inning when the Mets have a lead for defense. Plenty of outfielders with speed who can play defense can do this while hitting better than he has.
