Their lead reached nine points before George Washington's players snapped out of the funk.
Ward and Kelli Jo Harrison found a groove - Harrison while fighting foul trouble - and Capital's shooting touch began to cool off. Harrison had seven points and six rebounds in the fourth quarter, with Ward and Mobayed adding five points each.
"It's nice for Alanna to step up and give us another double-figure scorer," Pratt said.
Harrison finished with 25 points, Ward with 23, and Mobayed ended up with 14.
The trio was deadly from the foul line down the stretch with Harrison hitting 8-of-10, Ward 5-of-6 and Mobayed 4-of-6.
"Our foul shooting was the difference," Pratt said.
Keke Walker paced the Cougars with 18 points and Katisha Lee added 16.
Capital hit 8-of-13 from the floor in the third period and Lee scored 11 points.
Nobody was more relieved with the outcome than Pratt.
"In the 12 years I've coached with Jamie that is the first game he has missed," Pratt said. "I hope he is back for Saturday."
