NEW YORK - Alex Rodriguez's already strained relationship with the Yankees hit another low when he pushed to be activated from the disabled list today, the team refused and he had a lawyer join the discussion of his injury rehabilitation.

Already a target of Major League Baseball's drug investigation, the third baseman angered the Yankees when he obtained a second medical opinion on his strained left quadriceps this week without informing the team in writing, a step required by the sport's collective bargaining agreement. The Yankees intend to discipline him, most likely with a fine.

"Do you trust the Yankees?" Rodriguez was asked during an interview on WFAN radio.

"Um. You know, I'd rather not get into that," he responded.

Rivera gets the boot

ARLINGTON, Texas - The way Mariano Rivera helped kick the Rangers out of the playoffs, their parting gift was appropriate.

The Rangers honored Rivera before his final regular-season game in Texas, presenting baseball's career saves leader with a pair of cowboy boots inscribed with the New York Yankees logo, his name and No. 42. He was also given a cowboy hat before Thursday's series finale, and the team donated a $5,000 check for the Mariano Rivera Foundation that helps needy children.

Rivera has pitched 14 scoreless innings in 10 playoff appearances against the Rangers.
