"To be honest with you, I don't think he was 100 percent," Guillen said. "You're never 100 percent, but I think he looked a little slow. We'll see, it's going to take time, it was his first game back."
Kearns started in left field Friday night, and at times it looked like his hamstring may still be sore, including the third inning, when the Rays' Matt Joyce hit a blooper to shallow left off that turned into a double when Kearns was slow to get to the ball.
Guillen said Friday he would be cautious as he eased Kearns back into action, and the Marlins' skipper didn't plan on playing him in left field on consecutive days because of the hamstring, which caused Kearns to hit the 15-day DL on May 24. Guillen stayed true to his word Saturday, starting Donovan Solano in left for the third time this season.
Kearns was still in the lineup, though, starting at first while Logan Morrison sat out another day as part of a short mental break to help clear his mind of his struggles at the plate.
By once again sitting Morrison, moving Kearns to first and putting Solano in left and Justin Ruggiano in center field, the Marlins had seven right-handed hitters and two switch-hitters -- Jose Reyes and starting pitcher Carlos Zambrano -- in the lineup against Rays lefty Matt Moore.Kearns went 1-for-4 in Saturday's 13-4 loss.
