On Thursday, Toronto’s Whit Merrifield led off the bottom of the first with a single and Brandon Belt walked, but Flaherty retired the next 15 batters in order.
Kevin Kiermaier singled to begin the sixth and was ruled safe at second on Merrifield’s infield single after the Blue Jays challenged umpire Mike Muchlinski’s force out call.
One out later, Vladimir Guerrero Jr. hit an RBI single. George Springer walked to load the bases, but Flaherty ended his outing by striking out Matt Chapman and getting Alejandro Kirk to fly out.
Adley Rutschman and Hays each hit RBI singles off former Orioles right-hander Kevin Gausman in the second but left fielder Daulton Varsho threw Hays out at home plate to end the inning.
