Ryan Mattheus, Drew Storen and Rafael Soriano combined for shutout relief after Dan Haren nearly squandered a four-run lead, and the Washington Nationals beat the Detroit Tigers 5-4 Thursday to complete a two-game sweep of the AL champions.

Adam LaRoche singled in the first and second innings for his first consecutive multihit games this season, helping the Nationals to their first four-game winning streak of the year. Ryan Zimmerman, in a 2-for-14 slide coming in, had three hits.

Bryce Harper hit an RBI groundout in the first following Denard Span's leadoff double, and Harper came home from second when LaRoche singled and centerfielder Austin Jackson let the ball get past him for an error. Ian Desmond followed with a run-scoring single for a 3-1 lead.
