Whatever the case, the Rays just didn't seem themselves as they opened a series against the surprising second-place Rangers with a quiet 3-1 setback.

Aside from not being able to generate much of anything at the plate in one of the most hitter-friendly ballparks around, the Rays were uncharacteristically sloppy in the field, making key errors in the fourth and fifth innings that led directly to Texas runs and looking generally lethargic most of the night as they reached the 81-game midway point in their season.

"We did not have a good game tonight," said Manager Joe Maddon. "We made mistakes tonight and we could not come up with a clutch hit."

Unearned runs stemming from those errors proved to be the margin in Scott Kazmir's first career loss to his home-state team, though he chose to fault the hanging slider he threw to Hank Blalock in the fourth that ended up as a two-run homer.

"You don't throw that pitch to Blalock," Kazmir said. "Anything that's hanging, anything up - that's where he likes it, that's where he wants it."
