However, Manager Buck Showalter said there is still no timetable for his return.
"Until he gets on a regulation mound and throws downhill and has no problems, it's hard to put any time frame on it. That's the hurdle," Showalter explained.
Patton is dealing with what Showalter described as a "pretty severe strain" of his right ankle, something he has had issues with in the past. Showalter said Patton has had this type of injury before and that each time the area is injured and ligaments are damaged, it gets weaker.
While Showalter is hopeful the Orioles will get Patton back at some point in September, he said it is difficult to predict what type of performance they will get from a player who has spent a chunk of time on the DL.
But Showalter added that Patton is exactly the type of weapon that teams are searching for at this time of the year.
"A lot of people are looking for left-handed relievers in September," Showalter said.
Patton, 27, has appeared in 50 games and sports a 2.58 ERA, 1.03 WHIP to along with 48 strikeouts over 52 1/3 innings of work.
