Part of the reason behind that is the artificial turf at Rogers Centre.
"De Aza a day, the turf, get him off there, get him fresh. He looks fine," Ventura said.
Dewayne Wise, who matched a career high with four RBIs on Wednesday, got the start in center and hit leadoff.
As for Beckham, Ventura wanted to get him some rest Wednesday, and held him out of the lineup, but was forced to turn to him once Orlando Hudson exited the game after fouling a pitch off his foot in the sixth inning.
Ventura also believes some fatigue has set in with Beckham.
"He just looks tired. Just getting him out," Ventura explained. "His bat, it's just part of that year, that time of year.
"It's a long year, this is one of them you can't really see the end yet. This is a tough time of the year."
Ray Olmedo got the start at second and batted ninth.
Ventura has juggled the lineup every night during Chicago's four-game set with Toronto, but his players aren't complaining. The first-year manager has the respect of his locker room.
"He's very laid back. He understands how tough this game is. He understands you aren't going to win every game, that's the good thing about playing for a guy like him," Hudson said. "He's been through it all. There is a great communication factor over here."
