Their performance Sunday was especially pleasing to Scioscia, who returned from a three-game suspension.
Missing second baseman Adam Kennedy as they went for the four-game sweep over Seattle, the Angelse were also without ace relievers Scot Shields and Francisco Rodriguez, who both pitched in the first three games of the series.
The victory went to righty Brendan Donnelly who was a strong fill-in for the missing back end of the bullpen, delivering 1.2 innings of scoreless work while missing the strike zone just once in 13 pitches.
"But the off-day is much needed," Scioscia said.
When the Angels resume play Tuesday, they'll be trying to make up a 4 1/2-game deficit to the A's while hosting the Red Sox and Yankees for three games each.
The club will still have the services of Donnelly, who decided to appeal his suspension which was slated to begin Tuesday.
With Joe Saunders giving the all-clear after fatigue in his last start and Kennedy returning to the lineup, the club will be at full strength to start the critical run.
