Adam LaRoche ended an 0-for-15 start to the season with homers in consecutive at-bats, Jayson Werth and Ian Desmond also homered, and the Washington Nationals opened an early interleague series by edging the Chicago White Sox 8-7 Tuesday night.
Werth and LaRoche hit two-run shots off Jake Peavy in the sixth, an inning after Desmond went deep.
LaRoche added a solo homer in the eighth off Matt Thornton, Chicago's fifth pitcher. LaRoche had missed the previous two games with a back muscle problem.
The Nationals have 10 homers in their past three games.
Werth tacked on an RBI single off Matt Lindstrom for an unearned insurance run in the seventh.
The Nationals scored in their last five innings. That allowed Washington to hold on even though Alex Rios took closer Rafael Soriano deep for a two-run shot with two outs in the ninth. Soriano got Paul Konerko to fly out to end it and record his third save in four chances - barely.
