"No. No he's not," Gardenhire said when asked if Arcia was doing well. "He told me his hand was hurting. I brought him in here today to check on him and definitely his hand is hurting when he swings, a sharp pain.
"I told him, 'You're going to see the trainers and we're going to get this straightened out.' Because he's been trying to play through this thing, says he's fine. But he's not fine. We can see it in the way he's swinging. It's just not a good swing."
Arcia injured his wrist diving for a ball during a game against the White Sox two weeks ago. He was held out of the lineup for a few games, but has played since, making a start on Saturday in Cleveland. He went 0-for-4 with three strikeouts in the 7-2 loss.
Gardenhire noted that Arcia initially felt pain in the top of his wrist, but now it's more down on the outside of his wrist. As a result, Arcia's swing has notably suffered.
"I just wanted him to know, 'It's not like we're mad at you. If you're hurt, you're hurt. You just have to be honest with us and tell us you're hurt,'" Gardenhire said. "He wants to play and he wants to be a part of it, but he's not swinging very well.
"We'll let this guy get healthy. He's a big part of our future here and I don't want to see him do something silly and he's definitely not swinging good now. It's just not happening."
Arcia has yet to be placed on the disabled list, and as it's so close to September and expanded rosters, Gardenhire isn't sure if he'll need to move Arcia anywhere -- especially since the Twins will play with a short bench as long as Arcia's out -- but it does remain a possibility.
"We're so close to the [Sept. 1], where we could make a move," Gardenhire said. "They're [Triple-A Rochester] in a playoff race, but I won't rule it out."
