A.J. Ewing took the league by storm, playing his game to open his rookie campaign.After raking through the minors, the 21-year-old quickly settled in at the big leagues, establishing himself as a regular in the Mets outfield and atop their lineup.He did so by utilizing his speed and being his usual on-base machine.Like every rookie, though, Ewing was bound to go through his fair share of tough stretches at the plate as the grind of the regular season stretches on.Thats been the case for the youngster of late.With an 0-for-5 showing in Saturday nights loss to the Dodgers, he is now hitless across nine at-bats over the first two games against the defending champs.Ewing was also punched out two more times, giving him a whopping 26 this month.Hes currently tied with Francisco Alvarez for the second-worst K-rate on the team (26.7), trailing Brett Baty by percentage points for the highest (26.8).Despite the rough stretch, interim manager Andy Green isnt concerned.Every hitter goes through situations where things happen in bunches, he said.Its just about getting back to his strength -- when he first showed up it was laying off pitches out of the zone -- but its easy when you get into a situation where youve struck out more than youre comfortable you think you just have to swing, which typically makes it worse, the skipper continued.But hes going to be fine -- he has more punchouts than I know he is comfortable with right now, but hes learning and thats part of it -- I see him plenty capable that hes going to respond, but at this moment its time to punch back.The Mets certain need Ewing to punch back soon after losing a massive piece in the middle of their lineup this weekend, with Juan Soto landing on the IL due to a Grade 2 left calf strain.
