While acknowledging that ace right-hander Yu Darvish has seen significant improvement in the symptoms related to his elbow inflammation, Texas Rangers general manager Jon Daniels on Wednesday gave every indication that the pitcher’s season is over. Daniels said Darvish would be examined by team medical director Dr. Keith Meister in Arlington Thursday afternoon and then the next steps will be determined. “But time-wise, we are in the same place,” Daniels said. “The calendar is working against us. We’re going to make a common-sense decision. We are leaning towards not taking any chances.”
