MINNEAPOLIS -- The Minnesota Twins got two players back from the injured list only to lose one.

Both C.J. Cron (thumb) and Eddie Rosario (ankle) were activated from the IL ahead of Tuesday’s game with the New York Mets while the Twins placed Byron Buxton on the seven-day injured list (concussion protocol) retroactive to Sunday. The Twins also designated reliever Mike Morin for assignment.

Buxton hit the ground hard in the eighth inning of Saturday’s game against Cleveland, racing in and laying out to make a diving grab. Manager Rocco Baldelli said Buxton has been improving but that he was still dealing with symptoms.

“We’re not going to mess around, really, in any way. This is serious stuff. The health of Buck is obviously the most important thing,” Baldelli said. “…He hit the ground pretty hard, and this isn’t any sort of light injury. He didn’t graze anything. He made a great play and hit the ground, and he gives up his body for this team every single night that he takes the field. He really does give it up.”

While the team’s center fielder is now out of action, the Twins did get their left fielder back. Rosario missed 13 games with a sprained left ankle, which he suffered running the bases on June 26.

“It’s tough. It’s tough for everybody,” Rosario said. “I wanted to try to stay strong, recover fast. But I think everything’s fine right now.”

They also welcomed back Cron, who was sidelined with thumb inflammation. Cron said his thumb had been bothering him for “quite a bit of the year,” before the Twins placed him on the IL.

Because of the all-star break, Cron missed only five games.

“When I got put on IL, it wasn’t in the best of spots,” he said. “Pretty much any time I made contact not perfectly on the barrel, it was ringing pretty good in there. It’s nice just to let it calm down a little bit, and hopefully it won’t spark back up.”

The move to designate Morin, who was a non-roster invitee but pitched well for the Twins since an early May call-up, was somewhat of a surprise. He had a 3.18 earned-run average in 22 innings for the Twins. Baldelli praised Morin for pitching well and adapting to different circumstances — pitching in big spots, going periods of times without pitching, pitching without a lot of rest — that the team had put him in.

But ultimately, they needed a roster spot.

“When we’re adding guys and you start looking around for the right person, there is no right person,” Baldelli said. “You just have to go find what seemingly makes the most sense. When you make decisions like this, you can look back on them and you’re not really sure because things are not obvious sometimes, but unfortunately we landed on the thought of designating Mike.”

Briefly

Buxton was named the Twins’ Heart and Hustle Award winner, as voted on by former players. A final winner for Major League Baseball will be chosen from the 30 finalists.

“You don’t feel like he’s out there for himself. You feel like he is out there for his teammates, he is out there for this group and he’s out there to win,” Baldelli said. “That’s the reason he takes the field every day. He gives everything up for this team every day. I think he’s a perfect candidate, a perfect winner for this award, and I’ll be very happy watching him accept it.”

• Trevor Larnach, the Twins’ first-round draft pick in 2018, was promoted from Class-A Advanced Fort Myers to Double-A Pensacola. Larnach, 22, hit .316 with six home runs and 44 runs batted in in 84 games with the Miracle.

• Brent Rooker, the team’s No. 7 prospect per MLBPipeline, was placed on the Triple-A injured list with a bruised right groin.
