BAL@DET: Hardy dives to stop grounder, saves a run

DETROIT -- Shortstop J.J. Hardy was a late scratch from Sunday's game and had his batting practice cut short with another back spasm, this time in a different place.

Hardy almost missed Friday's game and had been dealing with a nagging back spasm, which he played through on Wednesday and Thursday before taking the series opener in Detroit off. Though his most recent spasm is in a different place, it's still a concern for the struggling Orioles, who have been without their starting shortstop for two of three games.

Hardy last season became just the fourth player to hit three or more home runs off Sunday's Tigers starter Justin Verlander in one season, and he entered the game a career .258 (8-for-31) with three homers and seven RBIs against Detroit's ace.

Ryan Flaherty moved from third base to take Hardy's place, with Jonathan Schoop getting the start at third.

Machado, injured O's make rehab progress

BOS@BAL: Machado updates on his rehab process

DETROIT -- Monday is a big day for a lot of the Orioles' rehabbers.

Manny Machado (left knee) is scheduled to have another functional baseball day on Sunday as he continues to make progress in his rehab. The bigger test after he does all the activities is to see how he feels on Monday, with Machado reporting on Friday -- following a day of activities -- that he felt great.

"His next step is hopefully running full-speed," manager Buck Showalter said. "The last thing he's had yet to do is sprint. And to be able to do it the next day and the next day, so to speak. I don't know when that's going to be."

Third baseman Michael Almanzar (knee) will start light baseball activities on Monday, with right-hander Luis Ayala resuming throwing in Triple-A that day as well.

Right-handed pitcher Dylan Bundy, the O's top prospect, is slated to throw a 30-pitch bullpen session on Monday off a regular mound, with Johan Santana scheduled for a situational side.

Outfielder Francisco Peguero, who has been strengthening his wrist since he had the cast removed last week, will resume baseball activities and start a hitting progression on Monday.

Worth noting

• In a perfect world, Showalter hopes David Lough can take over the leadoff role. Lough has been mostly a platoon player in left field with Nelson Cruz, but he could potentially earn some starts against lefties, similar to Nate McLouth last year, as the season progresses.

"We would like him to be able to do it," Showalter said. "It would fit everything better, especially when Manny gets back ... David's got the skills set to do it. We'll see.

"There's a different dynamic when he is on base. Any time you can make people rush a little bit and get in a hurry ... they hurry when David is hitting. He'll open up some things for some hitters behind him if he can get on base like he has."

• Double-A Bowie's Tim Berry had a solid debut on Saturday, pitching seven innings and allowing just one run on three hits while striking out seven and walking one.

• Friday's challenged play at second base called into question the newly enforced rule about what constitutes a catch after the fielder takes the ball out of his glove. "Everybody knows that's the way they are going to call it," Showalter said of a player having to secure the ball in the transfer. "They called it in Spring Training. You're going to see it with fly balls; guys are going to catch a ball, take a step or two, and go to take it out of their glove and drop it, and [the umpires] are going to call it a no-catch. They've told everybody that's the way it is going to be -- the intent of the rule completely, so to speak."
