McKinney will add a much-needed depth of field to a Mets club facing an injury rash in this area (and pretty much everywhere else). Michael Comfort, Brandon Nimmo, Kevin Pillar and Albert Almora Jr. are all on the injured list, and Johneshwy Fargas is about to join them on the shelf. Due to his injuries, the team went with a starting roster of Dominic Smith to the left, Cameron Maybin in the center and Brandon Drury in law during his victory over the Rockies on Tuesday.
McKinney, 26, who the Brewers nominated for an assignment on May 22, comes with good big-league experience in both corners of the outfield. The former first-round pick (No.24 in track and field in 2013) has seen time with the Yankees, Blue Jays and Brewers since making his debut in 2018, and he’s hit .226 / .285 / .422 with 21 circuits in 511 plate appearances. He won 100 PA with Milwaukee this year, but only hit .207 / .260 / .359 with three home runs. McKinney is out of minor league options, so the Mets won’t be able to send him without losing him.
Quintana, still 17, joined the Mets in the winter as a free agent for Venezuela. There is otherwise little information available on Quintana, but the Brewers believe it is worth taking a chance in exchange for an outfielder they felt was consumable.
Yamamoto went to the 10-day IL on the 23rd with shoulder pain, and his move to the 60-day version means he won’t be back until the end of July at least. Acquired from the Marlins in the offseason, Yamamoto has made two appearances this year and allowed six runs (five earned) in 6 2/3 innings.
