PHOENIX -- Outfielder prospect Andrew Stevenson was brought up from Triple-A Syracuse by the Washington Nationals, who put outfielder Chris Heisey on the 10-day disabled list Sunday because of a left groin strain.
Washington transferred outfielder Jayson Werth, who has a bruised foot, to the 60-day disabled list to open a 40-man roster spot for Stevenson. Outfielder Ryan Raburn was placed on the bereavement list, and catcher Pedro Severino was recalled from Syracuse.
The 23-year-old Stevenson, a second-round draft pick two years ago, was hitting .246 at Triple-A this year with two homers, 36 RBI and 10 steals.
