In doing so, the club was forced to option righty Jim Miller to Class A Stockton, where he has to remain for only three days -- rather than 10 had he been sent to Sacramento -- before being eligible to rejoin the A's on Tuesday.
It marks the fifth stint with the A's this season for Figueroa, who has compiled a 1.20 ERA and .170 opponents average spanning 11 appearances with Oakland. He logged a 2.45 ERA in seven relief appearances with Sacramento following his Aug. 7 option and has a 2.62 ERA in 32 relief appearances overall with the River Cats.
"He's been instrumental for us, whether it's multiple innings or matching up," manager Bob Melvin said.
Like Figueroa, Miller has done plenty of traveling between Oakland and Sacramento this season, having already endured three separate stints with the A's. The right-hander pitched just once in his most recent one, tossing 2 1/3 scoreless innings in Thursday's win in Cleveland.
