ANAHEIM, Calif. — Manny Machado remained out of the starting lineup Wednesday, a day after he was a last-minute scratch when he experienced lower back spasms during batting practice before the Orioles' 4-2 win over the Los Angeles Angels on Tuesday.
Manager Buck Showalter said he still considers Machado day-to-day, but the third baseman's return appears indefinite for now.
"I look for him to be back shortly, depending on how you define the word shortly," Showalter said.
Before Wednesday's game, Machado said his back felt better after he received treatment Tuesday. He was scheduled for another round of treatment during batting practice Wednesday.
"We're going to keep treating it, and hopefully it gets better," Machado said. "I know it's early, and it's getting better. That's a good sign of that so far.
"Definitey [encouraged]. I was kind of bummed out by it last night. … When I woke up, it felt a little better … I'm feeling much better. I assume that's a good sign for that. We're just going to feed off that and keep going."
Machado said earlier Wednesday that he hoped to be able to test his back during batting practice and see if he could loosen it up by running around, but he didn't participate in on-field pregame activities.
"He's better than he was yesterday. … It's a lot better than it being the same or worse," Showalter said Wednesday. "He didn't feel any of it until the second or third round of BP yesterday. I was asking if he felt it in Oakland, if he felt it before [that]. He said no."
Machado said he felt his back stiffen after a swing in batting practice Tuesday.
"It was just batting practice," Machado said. "It got tight on one swing and just started getting tighter and tighter. I don't know where it came from. Obviously, you take a lot of swings, so it kind of felt weird on a swing. That's where we're at now."
