Patton, who attended a court hearing in Texas stemming from a DUI arrest last winter, also will miss a game Sept. 22 to attend a mandatory orientation for court-ordered drug and alcohol classes. Assuming all goes as expected, Patton would have the charge expunged from his record.
"If I do it right, I will be done in February right when I am leaving [for Spring Training] and I won't have to deal with it at all next year," Patton said.
The 25-year-old Patton has pitched in 11 games for the Orioles, going 0-1 with a 3.86 ERA (16.1IP, 7ER). Hendrickson will have to go through optional waivers before reporting to Triple-A Norfolk. He is expected to clear and be put back on the 40-man roster on Wednesday.
The Orioles will make a pair of roster moves concerning their 40-man on Wednesday, clearing room for Hendrickson and one more player. With three new players expected to be added when rosters expand Thursday, Rick VandenHurk and Jeremy Accardo are two likely candidates to join the club. Neither pitcher is on the team's current 40-man.
