"Jarrett carried us," Wright said. "He went over to coach and said he wanted the ball and he made good things happen. It's one thing to request the ball, it's another thing to actually make things happen. He was aggressive on the pick-and-roll, he got to the basket and got fouled. That's what we needed."
Jack scored 11 in the fourth, including seven straight in one stretch, helping Toronto overcome a nine-point deficit.
"We know how desperately we need these wins coming down the stretch, making this final push at the end of the season, especially the ones at home," Jack said. "They're very crucial, they're very vital to how things are going to play out in the standings. We can't let these opportunities slip through our fingers."
Andrea Bargnani added 18 points, Hedo Turkoglu had 16, and Rasho Nesterovic and Jose Calderon each had 10 for Toronto, which topped 100 points for the 20th straight game and won its second straight with Bosh sidelined by a sprained left ankle.
Bosh, who missed his second straight game, was injured in the fourth quarter Wednesday night in a home loss to Memphis and did not travel to New Jersey for Friday night's win over the Nets, the first game he'd missed all season.
Andray Blatche scored 24 points, and Josh Howard had 17 as the Wizards failed to win three straight for the first time this season. Randy Foye added 14 points, and Al Thornton and JaVale McGee each had 10 for Washington.
"We put ourselves in position, we couldn't make a big shot to withstand their momentum," Wizards coach Flip Saunders said.
The Wizards led 100-91 with 5:40 left, but Jack hit a 3-pointer, then made four straight free throws to make it a two-point game. After the Wizards turned it over on a shot-clock violation, Turkoglu gave the Raptors a 101-100 lead with a three-point play.
Bargnani blocked shots on the next two possessions, giving Washington seven straight empty trips. At the other end, Wright dunked and Turkoglu made a bank shot to cap a 14-0 Toronto run, making it 105-100 with 1:34 remaining.
Bargnani had three of his four blocks during a 2-minute stretch in the fourth.
"Most people look to Chris as being our interior defensive guy," Jack said. "I thought Andrea, the last two ballgames, has done a great job of being that physical presence we need down low."
Blatche scored baskets on both sides of Calderon's two free throws, making it 107-104 with six seconds left, but Jack made two more from the line to keep Toronto safe.
"We should have had this game stowed away," Blatche said. "We just made a couple of mistakes down the line and they made us pay for it."
Nevertheless, Washington has looked better since trading away Caron Butler, Brendan Haywood, Antawn Jamison and DeShawn Stevenson over the past 10 days. Toronto coach Jay Triano said before the game that the moves have "cleansed" the Wizards, a sentiment Blatche shares.
"We're getting better," Blatche said. "I like our attitude, I like our hustle. We're going to be a great team."
Blatche scored 14 points in the third as the Wizards used a 22-6 run to erase a 10-point deficit. Washington led 88-85 heading into the fourth.
