Toronto is 41-28 at night, but the club entered play Thursday with a disappointing 15-26 record during the day.
Blue Jays manager John Farrell has tried to make multiple adjustments to the way his team prepares for matinee affairs, but so far there hasn't been an easy solution.
"If it has anything to do with the schedule, we've adjusted it to keep guys sharp," Farrell said. "Wake the body up, go through a condensed [batting practice], BP in the cage, go through a full workout.
"We continually seek ways to improve the overall daytime performance, because you look at our overall record and it's respectable. Yet the daytime, if we played to .500 in days, we'd be looking a much improved overall record."
Toronto's winning percentage during the day is the worst in the American League. Only Houston (.286) and Colorado (.333) have worse daytime marks in the Major Leagues.
