Discouraging article in the Times about Reyes:
Mackie Shilstone, a sports-performance expert "said he examined the 21-year-old Reyes for three days last October and determined 'in no uncertain terms' the root of Reyes's problems... Shilstone said he advised Reyes to visit him for two more weeks before playing in the Dominican Winter League and to see him for two weeks after the league ended to make any necessary adjustments to his conditioning regimen.
"'He chose none of the above,' Shilstone said. 'We didn't get to put all the pieces together. So I can't sit here and tell you the deficits are gone. I think the jury's out.'
Shilstone said he gave Reyes a 'partial plan,' about a fourth of an overall regimen that Shilstone feels is necessary to really put Reyes on safe ground. Shilstone surmised that Reyes, following his plan, began feeling better and thus assumed he was healthy."
Reyes said "he does only some of the exercises that Shilstone recommended because there were so many of them."

But don't worry. Omar's on top of things. When asked what Reyes is doing differently these days, he responded "That's a good question. I'm not sure. We monitor it with our trainers."
