"The fields have been very wet, it's been very cold," Trembley said before Wednesday's Spring Training opener against Tampa Bay. "Nolan knows that. He's perfectly healthy, but we're going to take our time with him, seeing that it's March 3, 4 and 5."
Reimold had successful surgery to repair a partial tear of his left Achilles tendon on Sept. 23, correcting an ailment that bothered him all last season. Projected to be the O's starting left fielder -- as part of a platoon with Felix Pie -- Reimold arrived at camp with no restrictions and has been participating fully in all baseball-related activities.
"It is [still sore], but it's an expected soreness," Reimold said of the tendon. "So there's nothing to be alarmed about. Just [need to] work my way into it. I'll be fine."
Reimold said he had no problem with Baltimore's preference to be cautious, and he was scheduled to work out with the rest of the non-game participants Wednesday. Reimold played in the team's intrasquad game Monday, and although he appeared to be running fairly hard, Reimold isn't quite full throttle yet.
"I ran down [the first-base line], but I try not to go full, full speed until I don't have any pain," he said.
Trembley said Reimold might get in the games on Friday or Saturday, but a lot of that decision will depend on the weather, which has been unusually harsh for Florida.
"[On] Friday, [if it] is going to be 45 degrees out there, [it] probably wouldn't be in his best interest or our best interest to [play Reimold]," Trembley said. "But we'll see."
After a torrid start at Triple-A Norfolk, Reimold made good use of his callup to Baltimore. In his first 104 games, he batted .279 with 15 home runs and 45 RBIs.
