Nats put Stephen Strasburg on DL with an upper-back strain

The Washington Nationals have placed Stephen Strasburg on the 15-day disabled list with an upper-back strain.

The move, which was announced before Sunday's game against the Brewers, is retroactive to June 16, meaning Strasburg is eligible to be activated as early as Friday.

The Nationals announced Saturday night that Strasburg had been scratched from his scheduled start Sunday in Milwaukee.
