Johnson, who went 2-for-5 with an RBI double in Tuesday's 7-6 win over Miami, now ranks fourth in the American League with a .571 slugging percentage.
Evan Longoria said he hasn't been surprised about Johnson's bat -- he leads the team in home runs with 10 -- but Longoria noted that Johnson is more than just a productive hitter.
"I played against Kelly for a half a year in Toronto, and I had seen him play in the past on TV, and I know he's a talented guy, and he does a lot of things well," said Longoria, citing Johnson's alert steal of third base in Monday's game. "Even last night, him stealing third in that situation, that was a smart baseball play. That's kind of what he brings to this team, not only his ability to hit the ball, but just a total character baseball player. Being able to play multiple positions. Obviously something [Rays manager] Joe Maddon likes and he's taken to all of that really well."
