BALTIMORE -- The Orioles set their Minor League coaching staffs on Thursday, keeping several of their managers in place and shuffling pitching coaches at the highest levels. Gary Allenson and Brad Komminsk will return in their respective capacities as the managers at Triple-A Norfolk and Double-A Bowie, and Orlando Gomez will move up to manage Class A Frederick.

Allenson, a manager for 15 seasons, has spent five years in Baltimore's organization. He has managed Norfolk for three seasons, racking up a 204-223 record along the way. Much of Allenson's staff will be new, highlighted by pitching coach Mike Griffin and hitting coach Richie Hebner. Griffin served last season at Bowie, while Hebner managed Frederick.

Mark Shires, who was named the International League Athletic Trainer of the Year in 2009, will return for his 11th season in the Baltimore organization and his fourth at Norfolk. Allenson's staff will be rounded out by bullpen coach Greg Grall.

Komminsk has posted a winning record in both of his seasons with Bowie and was named Eastern League Manager of the Year in 2008. Kennie Steenstra will replace Larry McCall as the pitching coach at Bowie, but Moe Hill will return for his fifth year as field coach. Joe Benge will serve as the athletic trainer in Bowie for the third season.

Gomez, a former batting practice pitcher with the Orioles, will move up to Frederick after managing Delmarva last season. Gomez, the 1989 South Atlantic League Manager of the Year, has been in baseball for 47 seasons, 34 of them as a scout, coach or manager. Blaine Beatty will be his pitching coach at Bowie, and former big leaguer Denny Hocking will serve as field coach.

Ryan Minor spent the past two seasons as hitting coach at Delmarva, but he will move up to the manager's office. Minor will be assisted by pitching coach Troy Mattes and field coach Mike Devereaux, both in their first year with the team. Devereaux played 12 seasons in the Majors and will be counted on to help tutor outfielders on their routes to the ball.

Things are a little more stable at Class A Aberdeen, which will be helmed by Gary Kendall for the third season. Former Oriole Scott McGregor will return for his third season as Abderdeen's pitching coach, and coach Cesar Devarez will return for his sixth.

Former big leaguer Einar Diaz will manage Rookie Level Bluefield for the second straight season, and he'll be flanked by McCall and coach Leo Gomez. Ramon Sambo will round out the manager roster for the Gulf Coast League Orioles. Former Oriole Calvin Maduro is his pitching coach, and Milt May will join the organization after a long coaching and scouting career elsewhere.

Former shortstop Mike Bordick will join the organization as a Minor League infield instructor, and the Orioles will return Don Werner, Butch Davis and Denny Walling as their roving instructors.
