"It's just the way [Kazmir] looks right now, watching their followup and their workouts," Maddon said. "It just seems it was easier to let Kaz go on at this point than it was for Shields. Also, we talk about the number of pitches, but the up and down does matter. I just felt like Kaz was a little fresher right now than Shields."
Injury update: Carl Crawford and Brendan Harris were out of the lineup again on Sunday -- Crawford with a strained left groin and hamstring, and Harris with a strained left shoulder.
"Nothing [new on either]," Maddon said. "Carl's the same, so's Harry. I don't expect either one to play today."
According to Maddon, Crawford's recovery has "kind of plateaued."
"I'm not so sure right now that he's going to be able to do this," he said. "[I was] a little more hopeful the first game back, but it just doesn't seem like it's going anywhere that we need it to go for him to participate right now. He has made progress, just not to the point where he comfortable with it."
Upton first 20-20 Ray: By stealing his 20th base of the season on Saturday night, B.J. Upton -- who has 24 home runs on the season -- became the first player in Rays history to have 20 steals and 20 home runs in a season.
In addition, Upton was hitting .303 entering Sunday's game.

'Los on the loose: First baseman Carlos Pena hit his 41st and 42nd home runs of the season on Saturday. In doing so, he recorded two homers in a game for the 12th time in his career and tied Jorge Cantu (2005) for the most multi-homer games in a single season, with four.
Pena's four RBIs on Saturday gave him 116 for the season and left him one shy of Cantu's club record of 117 (2005).
Pena's 42 home runs are eight more than the Rays' previous record of 34 (Jose Canseco, 1999; Aubrey Huff, 2003) and 15 more than his previous career high (27, with Detroit in 2004). His 116 RBIs are 24 more than his previous career best (82 with Detroit, 2004).
