With a late lead to protect, the Redskins' defenders were grinning. They knew they could step up when the punchless Rams suddenly made it a game. Ryan Torain ran for 135 yards and a 20-yard score, and Washington overcame a potentially devastating late turnover with two of its seven sacks, as Stephen Bowen and Brian Orakpo made plays that backed St. Louis out of scoring position in a 17-10 victory Sunday.
