Shane Doan added an empty-net goal with 11 seconds left.
Head Coach Dave Tippett said a few roster cuts likely would be made on Saturday. Several prospects who played well this preseason are making the roster decisions challenging, but the 23-man roster must be submitted to the League on Tuesday.
"They continue to impress - a lot of them - but as you get deeper in exhibition (season), and you start to play against teams like that (San Jose), that are more NHL players, you see some good things but also you see some flaws, too," Tippett said. "So you try to manage that. For us, it's about getting our whole team together now with the best lineup we can."
He added: "We're going to sleep on a few things and we'll probably get things down in the morning a little bit."
Not counting a scrimmage in Tucson on Sunday, the Coyotes are off until Oct. 15 when they open the regular season at home vs. the Philadelphia Flyers.
