"Very impressive," manager Ned Yost reported. "Much better than I'd thought he'd look. He threw two sessions of 20 pitches, so he ended up with 40 throws at probably 65 feet. He looked very free, very easy."
Kendall also took some swings off a batting tee in the cages.
He's recuperating from shoulder surgery last September.
Catcher Lucas May, who's competing with Brayan Pena and Manny Pina to replace Kendall early in the season, returned to the workouts Friday after a battle with the flu.
"He had a 101-degree fever yesterday, and I told him to stay home. I don't want that thing circulating through here if we can avoid it," Yost said.
May caught batting practice, hit and did defensive drills.
