Blake day-to-day after latest evaluation

GLENDALE, Ariz. -- It was Casey Blake's back, and not ribcage, after all. Regardless, the prognosis remains the same and it's relatively upbeat. He's basically day-to-day, with his return to the field dictated by how long it takes for the inflammation to subside.

The inflammation is to the lower thoracic spine, with pain radiated to the rib area.

Apparently, that is similar to the injury that sidelined him for four games last summer, with fear of something more serious set aside when he responded to an injection. The difference is the location of the radiated pain.

Dr. Robert Watkins Jr., who examined Blake on Sunday, told the club an MRI showed no indication of a strain of the oblique or intercostal muscles of the ribcage and Blake can return to field work when the pain subsides. No further tests are planned.

The 37-year-old Blake originally felt muscle spasms trying to leg out a sacrifice bunt Saturday and initially said he felt this was the same injury as last year, but the next day the discomfort was more to the side of the back near the ribs.

"I feel a little better today, but I still feel it," he said Tuesday.

Juan Uribe started at third base for Tuesday's 7-6 win over the Rangers, committing an error on a cue shot, and manager Don Mattingly said Uribe would be seeing more time at the position.
