Both relievers were called up from Triple-A Sacramento after Oakland's relief corps was forced to throw 18 1/3 innings the last two games, thanks to Friday's 15-inning marathon and starter A.J. Griffin's injury in the second inning of what became an 11-inning game on Saturday. The A's also played a 15-inning game on Monday.
To make room for the pair on the roster, outfielder Michael Taylor was sent back down to Sacramento. One spot was also opened up when the team placed Griffin on the DL on Sunday.
"You look at the bullpen usage here in the homestand, and this is very much needed," A's manager Bob Melvin said.
The move gives the A's nine relievers for the time being and only three bench players. That number could have been two, had outfielder Yoenis Cespedes not been healthy enough to return from his wrist injury on Sunday.
"With Michael Taylor, unfortunately, somebody had to go for a reliever," Melvin said. "We'll play a little short on the bench. Even if Yoenis wasn't able to play today, we probably would've made that move and gone with an even shorter bench. We do need bullpen reinforcements. We're not going to push that."
Both relievers appeared in Sunday's game after starter Tommy Milone exited. Scribner allowed three hits in two shutout innings, while Figueroa threw one perfect frame.
It's the second time in three days that Taylor and Scribner have exchanged roster spots. Scribner and reliever Jim Miller were just sent down on Friday to make room for Taylor and catcher Derek Norris after the Kurt Suzuki trade.
Before Sunday, Scribner had a 1.93 ERA in 12 appearances for the A's this season and joins them for the third time. The left-handed Figueroa, meanwhile, is making his fourth stint with the team. He had a 1.50 ERA in nine appearances with Oakland before Sunday's action.
