The Jays picked up another run in the fourth when Mike McCoy singled home Davis, who had reached on a fielder's choice and then stole second and third base. Davis has 18 stolen bases this season.
"I feel like I cost myself a run in the fourth, the last run they got off me," Arrieta said. "Really didn't do a good enough job paying attention to Davis at second base. I was quick to the plate, but with a guy like that, you've really got to do a better job."
Arrieta again wrestled with his control, but he retired his final seven batters and left with the lead after Reynolds' grand slam. He threw 99 pitches (57 strikes) in six innings while allowing five hits, four walks and three earned runs. He threw 80 pitches through four innings before salvaging his start with 19 in the final two.
"My outing, it was pretty ugly, to be honest with you," Arrieta said. "Mindset was the same from start to finish. Things really fell into place in the fifth and sixth. Didn't get off to a great start, but I was able to keep us in there."
Jim Johnson threw just six pitches in a perfect seventh, Koji Uehara struck out three of the four batters he faced in the eighth and Kevin Gregg, in typical fashion, allowed two singles in the ninth, but got a strikeout and pop-out to secure his 10th save.
"They let us hang around a little bit and we beat a really good pitcher tonight, which is something we've done two or three times this year," Showalter said. "And I'm real proud of them."
