The Arizona Fall League rosters were announced Tuesday, and seven Orioles minor leaguers will represent the organization with the Glendale Desert Dogs this season.

Three right-handed pitchers -- Parker Bridwell, Zach Davies and Mychal Givens -- and one left-hander -- Ashur Tolliver -- will head from the Orioles organization to Glendale, as well as three position players -- outfielder Dariel Alvarez, catcher Michael Ohlman and infielder Jason Esposito.

Triple-A Norfolk pitching coach Mike Griffin also will join Glendale as the co-pitching coach, and short-season Single-A Aberdeen's Chris Poole will serve as the team's athletic trainer.

Alvarez, who was promoted to Norfolk at the All-Star break after beginning the season at Double-A Bowie, has batted .306 with 15 home runs and 82 RBIs in 128 games between the two levels heading into Tuesday. He has a 14-game hitting streak through Monday.

Bridwell is 6-10 with a 4.51 ERA in 25 starts for High-A Frederick this year, while Davies is 10-7 with a 3.03 ERA in 19 games (18 starts) for Bowie.

Tolliver and Givens have split time between Frederick and Bowie this year. Tolliver, who is currently on the minor league disabled list, is 3-2 with a 2.89 ERA in 27 games between the two levels, while Givens is 1-2 with a 3.54 ERA in 34 appearances through Monday.

Through Monday, Ohlman was hitting .241 with two home runs and 30 RBIs in 105 games for Bowie this season. Esposito has a .266 batting average, eight home runs and 44 RBIs in 118 games for Frederick heading into Tuesday.
