Rockies Ubaldo Jimenez has mental fatigue?

Rockies ace Ubaldo Jimenez and manager Jim Tracy both dismiss the suggestion that the right-hander is physically tired. But Tracy hinted that the mental strain might be wearing on the 26-year-old after he carried the team for two months while receiving national attention for his accomplishments. “He has shouldered a heck of a burden. He’s raised the bar to a level that maybe he’s not quite ready for yet,” Tracy said. Jimenez believes a mechanical adjustment — staying taller in his delivery — will steer him out of his funk. “I beat myself (Saturday). But I can fix this,” he said. — Denver Post
