Walls doubled in the ninth and later scored on a wild pitch and an errant throw to third by catcher Danny Jansen.
“He played great defense, make some nice plays and came up with big hits,” Tampa Bay manager Kevin Cash said.
Cash is unsure of Kiermaier’s status for Sunday.
“I think he’s going to be fine,” Cash said. “He’s got a scratch in his eye that he kind of was batting through. He didn’t want to come out of the game. It just didn’t make the most sense at that point when he said he was having to blink a lot.”
After scoring 72 runs during the first eight wins, Tampa Bay generated just enough offense. Five Rays combined on a six-hitter to send Toronto to its fourth straight loss.
“This game has got a lot of ups and down,” Margot said through a translator. “So we have to stay kind of even keel to maintain that positive energy and keep that motivation going game in and game out.”
Rays starter Shane McClanahan allowed one run and four hits in five innings. Andrew Kittredge (4-0) threw a scoreless seventh and Diego Castillo worked the ninth to get his eighth save.
Toronto’s Robbie Ray gave up one run, five hits and struck out seven in seven innings. The lefty has fanned 49 and walked just one over his six starts.
Tampa Bay had a streak of scoring seven runs or more in six straight games end. The Rays had also had hit three or more homers in five consecutive games, which was one away from the longest streak in major league history of six set by the 1987 Baltimore Orioles.
Walls was recalled from Triple-A Durham. … RHP J.P. Feyereisen, also acquired from the Brewers, worked a scoreless sixth.
When Rays 1B Ji-Man Choi struck out swinging in the fifth, he lost control of his bat and it wound up in shallow right field.
Rays: RHP Michael Wacha (right hamstring tightness) will reinstated from the 10-day IL to start on Sunday.
Blue Jays: 3B Cavan Biggio was placed on the 10-day IL with a cervical spine ligament sprain. … CF George Springer (right quadriceps strain) is running sprints at 50-60 percent.
Blue Jays LHP Hyun Jin Ryu (4-2) will start on Sunday. Wacha is 1-1.
