Nats' third baseman Rendon seeks 3rd opinion on knee

VIERA, Fla. (AP) Washington Nationals third baseman Anthony Rendon was scheduled to meet with Dr. Steven Singleton in Vail, Colorado, for a third opinion on his injured left knee.

Dr. James Andrews on Monday confirmed the team's initial diagnosis of a sprained medial collateral ligament, and Rendon was to be examined by Singleton on Tuesday.

''We're just trying to make sure we cover all bases and everybody gets a chance to take a look it and develop a course of action from today on.'' Nationals manager Matt Williams said.

Rendon was hurt making a diving stop against Atlanta on March 9.

Washington has used Danny Espinosa and Ian Stewart at third since Rendon's injury. However, with the uncertainty of when Rendon will be back, Yunel Escobar has volunteered to play there, with Espinosa moving back to second.

The Nationals also agreed to pay left-handed reliever Rich Hill a $100,000 retention bonus. In camp on a minor league contract, Hill has allowed two runs over 6 1-3 innings in seven spring training appearances with eight strikeouts and three walks.
