BALTIMORE – Even after the Mets announced Tuesday that Starling Marte was headed to the injured list, the net sentiment was largely positive, particularly for a team that’s recently been beset by health concerns.

Yes, Marte is on the IL retroactive to Monday with what's believed to be a bone bruise on his right knee, but manager Carlos Mendoza called it “relatively good news” that should see him back in the lineup after the All-Star break. And then, as if in diametric opposition to the parade of injuries that sunk their June, the good news kept on coming.

After over two months on the IL with an oblique injury, Jesse Winker was activated and in the lineup for their game against the Orioles Tuesday, DHing and batting fifth. Kodai Senga, returning from a hamstring strain, is penciled in to return to the rotation Friday against the Royals; he’ll be on a pitch count, Mendoza said. And Sean Manaea, making a rehab appearance with Triple-A Syracuse Tuesday, could join Senga soon after – pitching Sunday in the last game before the All-Star break.

Concerns about Marte’s knee cropped up in the ninth inning of the Mets' loss to the Yankees Sunday, when the outfielder was visited by trainers. But though Marte has yet to get imaging – that’s scheduled for Friday in Kansas City – Mendoza seemed fairly confident that this is a recurrence of an injury that’s intermittently bothered him since last season, and nothing more serious.

While that injury sidelined him for nearly two months last year, this instance appears to be “just the wear and tear,” Mendoza said. “The trainers are pretty confident that that’s what we’re dealing with here and even with Marte today, talking to him, he’s in a pretty good spot.”

He’s also been heating up: In his last 12 games, Marte, who began the season mostly coming off the bench, has been pivotal – slashing .356/.388/.400.

“Especially with the way he was playing, he’s been a force for us, even at the top of the lineup, the middle of the lineup, wherever we put him – put him in the outfield,” Mendoza said. “But again, we’re thinking this is something that’s going to be short…

“It’s funny how things work – you gain one, you lose one.”

The gain is, of course, Winker, who Tuesday said he was “back to a good spot and just happy to be back.”

Before getting hurt on May 4, Winker was batting .239/.321/.418 with a homer and 10 RBIs, but proved himself a valuable asset last year when he was acquired before the trade deadline and became a key piece of the Mets playoff run. In five minor-league rehab games, he hit .286 with a double, two homers and seven RBIs.

Watching the team struggle last month while he was stuck on the bench “is part of baseball,” he said. “Any time you get hurt, it’s frustrating, right? But it’s the nature of the beast…Obviously, you want to help any way you can and, for me, it was waiting for my body to get in a better spot.”

Right-handed reliever Alex Carrillo was selected to the roster after 22 minor-league games. Carrillo, 28, who hails from the Independent League and was signed out of Venezuela last summer, throws a 100-mph fastball, as well as a slider, cutter and changeup. Carrillo struggled early in his career before drawing attention last season with the Washington WildThings of the Frontier League. He hasn’t allowed a run in four appearances (5 2/3 innings) with Syracuse this year, and pitched to a 4.19 ERA in 15 games (19 1/3 innings) with Double-A Binghamton. “We’re going to give him a good look here,” Mendoza said. Reliever Zach Pop was designated for assignment in a corresponding move…Mendoza plans to get Clay Holmes another outing before the break, meaning that if Manaea returns, both could pitch Sunday…Tylor Megill (elbow sprain) was transferred to the 60-day IL, though Mendoza said this wasn’t a setback. “It’s just where he’s at in his progression,” Mendoza said. “He’s still throwing, he’s still going to go through the progression and then we’ll continue to build him up." Megill hit the IL on June 17 and Mendoza said then that a four to five-week absence was a best-case scenario. The earliest Megill can now return is mid-August.
