Markakis back in action with baseball activities

SARASOTA, Fla. -- Orioles right fielder Nick Markakis hit off a tee, threw and ran at the team's spring facility on Friday in his first day of baseball activities since suffering a small disk herniation in his neck earlier this month.

"He's got that grin on his face where he's going, 'Why are we doing this? Why don't we just start playing games?'" manager Buck Showalter said of Markakis, who last played March 1 and is targeting being ready for Opening Day.

To do that, Markakis will play in a lot of games at the Minor League complex. He will progress to some soft toss on Saturday and could hit batting practice off some of the coaches on Sunday.

"Don't hold me to it, but that's what the plan is," said Showalter, who sat down with Markakis several days ago to map out a schedule that will have him getting at-bats starting next week.

Markakis was cleared on Thursday after speaking with spine specialist Dr. Lee Riley. He's been receiving regular treatment and is pain free with full range of motion returned in his neck and upper back. Markakis has played in four games this Grapefruit League season, going 3-for-12 with an RBI and two strikeouts, and he will probably lead off in multiple Minor League games to catch him up to speed.

Slated to be the team's starting right fielder, Markakis has played in at least 160 games in three of the last four seasons.

O's at impasse regarding Sept. 5 game

PORT CHARLOTTE, Fla. -- The Orioles, White Sox and Major League Baseball couldn't reach a mutual agreement with the Baltimore Ravens that would allow the Sept. 5 night game to be played at 4 p.m. ET -- and allow the football game to be played that night -- and the O's released a team statement on the matter on Friday afternoon.

"The Orioles have great respect for the Super Bowl Champion Ravens and thank Major League Baseball, the MLB Players Association and the White Sox for doing everything possible to work with us to explore all options to reschedule the Sept. 5 game," the statement said.

"We also appreciate the work of the NFL and the Ravens over the past several weeks as we attempted to accommodate the Ravens' interest in a game the same evening. Given the limited options available to reschedule the game at that late date in the season, the parties jointly determined that even an earlier start time would still create such enormous logistical difficulties that it would greatly diminish the fan experience for both events which all parties realized would not be in the interest of their fans or the city."

Redmond claimed off waivers by rival Blue Jays

SARASOTA, Fla. -- Right-handed pitcher Todd Redmond was claimed off waivers by the Toronto Blue Jays on Friday afternoon.

The move leaves the Orioles with 39 players on the 40-man roster and Redmond, upon being acquired, was optioned to Toronto's Triple-A club. The O's claimed Redmond on waivers over the winter from the Cincinnati Reds, and he pitched to a 5.63 ERA in five spring games before being optioned to Minor League camp on March 16.

Worth noting

• Tommy Hunter and Jason Hammel threw at the Minor League complex on Friday to get in their innings.

• Reliever Mark Hendrickson is due back in camp Saturday after flying home on for the birth of his daughter in York, Pa., on Wednesday.

• Ed Flaherty, the father of Orioles infielder Ryan, won his 800th game on Thursday to make him the 13th coach in NCAA Division III history to reach the milestone. Flaherty's overall career record stands at 800-370-4 over 28 seasons.

• Chris Tillman will start Sunday's game, with Brian Matusz pitching in the Minor League game that afternoon.
