Gonzalez played a brief stint with the O's from May 29 to June 9, allowing two earned runs in 7 1/3 innings during two long relief appearances.
Gonzalez had been used as a starter since returning to Norfolk, posting a 2.31 ERA in the six outings since his return. But the Orioles will be using him in the bullpen, after normal long relief options Hunter and Dana Eveland both pitched on Saturday.
Hunter is 3-4 with a 6.11 ERA, after allowing five runs on eight hits and a walk in 1 2/3 innings of relief on Saturday against Cleveland.
Avery was optioned back to Norfolk after being recalled on Thursday and making three consecutive starts in left field. Avery recorded a hit in each game, including his first career home run on Friday.
Thome went 0-for-4 in Sunday's game, while Gonzalez allowed one run in 4 1/3 innings of relief.
