O's set instructional league roster, schedule

BALTIMORE -- The Orioles will host the team's fall instructional league at Ed Smith Stadium in Sarasota from Sept. 16-Oct. 8, with games free and open to the public.

The O's roster features 54 players, including 27 pitchers, 10 infielders, 10 outfielders and seven catchers.

Top Draft pick pitcher Hunter Harvey, along with outfielders Josh Hart -- the club's supplemental first-rounder -- and recent signee Dariel Alvarez are on the roster. An additional six players, including top pitching prospect Dylan Bundy, were listed as rehabbing.

The games are played on the Main Field, with parking available in the East Lot at no charge. Spectators may enter the ballpark through the East Gate.

The full instructional league season schedule is available online at orioles.com/sarasota, with the team's first home game set for Sept. 16 at 1 p.m. ET against the Tampa Bay Rays.

Markakis won't be placed on paternity list

BALTIMORE-- Nick Markakis' wife, Christina, is scheduled to induce labor for the couple's third son on Wednesday morning, and assuming all goes well, the Orioles' right fielder is planning on playing later that night.

"That's the way he's got it set up. We'll see," manager Buck Showalter said on Monday."It's one thing to induce. It's not like going to the dentist. I just hope everything goes well, and when he gets here, he gets here. I'm planning on him being an 'If' on Wednesday. I hope that happens and everything runs smoothly."

Markakis won't go on the paternity list with expanded rosters affording the club extra players and space if they need to make an additional move. Marred in the most prolonged slump on his career, Markakis -- who entered Monday's game with one homer and 10 RBIs in the second half -- was slated to bat leadoff against Yankees ace CC Sabathia.

Sabathia ended Markakis' season last year in mid-September after hitting him with an inside fastball, snapping the left-handed hitter's stretch of three consecutive seasons of at least 160 games played. The scuffling Markakis, who was not in Friday's starting lineup, has appeared in all but two of the Orioles' games this season and owned a .269/.323/.355 line entering play Monday.

Worth noting

Steve Pearce got a cortisone injection in his ailing left wrist on Friday and Showalter hopes he can return for the club relatively soon. Pearce's first eligible date is Thursday, which probably would be a reach, but the club is hopeful he can be added to the expanded roster not long after that.

• Infielder Alexi Liddi cleared waivers and has been outrighted to Triple-A Norfolk.

Nate McLouth stole his 30th base on Saturday, becoming the ninth Oriole to steal 30 or more in a season and give the Orioles their 19th season with at least one player to hit that mark. Second baseman Brian Roberts has a club-record four 30-steal seasons.

• Roberts got the day off from starting Monday in favor of infielder Alexi Casilla. Casilla entered Monday 16-for-31 off Sabathia, and Showalter said this was a good spot to give Roberts a breather with the team having just one more schedule off-day.
