Outfield Collision Sidelines Orioles' Trent Mummey

BALTIMORE—High Class A Frederick center fielder Trent Mummey left Harry Grove Stadium in an ambulance after crashing into the fence and suffering a concussion.
The injury occurred during a May 4 game against Winston-Salem, and it made an entire organization hold its collective breath.

Mummey, a fourth-round pick in last year's draft out of Auburn, had recently been promoted from low Class A Delmarva. The 22-year-old was hitting .280/.366/.462 with two homers, 18 RBIs, 14 steals and an .828 OPS in 24 games between the two affiliates.

Mummey's head slammed into the fence in left-center field as he dived for a fly ball from Winston-Salem catcher Luis Sierra. Miguel Abreu retrieved the ball and shook Mummey, who laid motionless on the warning track as Frederick's trainer ran out of the dugout.  

Two runs scored on the play, but that was the least of the Keys' concerns.
Later that day, Mummey tweeted the following message:

"Thanks for all the wishful thoughts! Scary moment but I'm thanking God that everything is going to be ok. #countingmyblessings"

Mummey, who's listed at 5-foot-9, 167 pounds, will have to pass a concussion test before he's cleared for baseball-related activities, so he won't be playing anytime soon.

"He's a ways away," farm director John Stockstill said. "He's feeling much better, but I would say it's an undetermined amount of time. The original plan was about three to four weeks before doing a status check at that point."

Mummey hit a combined .245/.318/.379 with 16 doubles, five triples, three homers, 29 RBIs and eight stolen bases in 261 at-bats last summer between short-season Aberdeen and Delmarva. He was named to the New York-Penn League all-star team.

Bird Seed

• The Orioles also received a huge scare when prized shortstop Manny Machado dislocated his left kneecap while running the bases in a May 5 game at low Class A Asheville. Machado, the third-overall pick in last June's draft, had to be carried off the field, but he didn't suffer any tears or breaks. He went on the disabled list, but could return to Delmarva's lineup around the start of June.

• Righthander Jesse Beal, who pitched at Delmarva last summer, had surgery May 3 to repair a torn labrum. Beal, a 14th-round pick in 2008 out of South County High in Virginia, was 7-6, 3.86 in 114 innings last year. He was expected to pitch at Frederick this season.
