Bryce Harper sat out after a procedure to fix an ingrown toenail. Jayson Werth has been sidelined for a week with a bad hamstring and the plan is to put him on the disabled list. So what if two of Washington's best hitters watched from the dugout Friday night? With extra-base hits coming from lower in the order, the Nationals extended their season-high winning streak to five games. Ian Desmond's three hits included a two-run homer and an RBI double, and Danny Espinosa and Kurt Suzuki each drove in a pair of runs with a double, helping Washington beat the Chicago Cubs 7-3 for its seventh victory in the past eight games.
