Toronto starter J.A. Happ had just struck out Rays leadoff batter Brandon Guyer and he got ahead in the count 1-2 to Motter, who watched an 84-mph changeup pass to even the count at 2-2.
Happ then delivered a 92-mph fastball that Motter put in play softly to the right side. First baseman Justin Smoak fielded the ball, but he quickly discovered he'd drifted far from the base. Motter scooted up the line and won the race to first base to record a single and his first Major League hit in his first attempt in the bigs.
Motter's contribution paid instant dividends for the Rays as Steve Pearce followed with his sixth home run of the season on Happ's next pitch to put the Rays up 2-0.
"I think the hit was big, especially for me, and the team," Motter said. "Then Pearce goes up and hits a two-run shot."
After the fifth inning, with the game well in hand, Rays manager Kevin Cash took advantage of Motter's versatility by moving him to right field in the midst of wholesale late changes to get some regulars off their feet.
Motter finished 1-for-4 with a walk and two runs scored.
When asked if he got the ball from his first hit, Motter smiled: "You know what, I'm just trying to float back to Earth right now. Going to see what they're doing with it. Hopefully get it back to the Trop and see what they're doing with it then."
