Nationals first baseman Adam LaRoche continued to swing a hot bat as he launched two home runs during Friday's game against the Padres.

LaRoche took starter Burch Smith deep for a three-run shot in the fourth inning. He took Smith deep again in the sixth inning for a solo home run. He finished 2 for 4 with two runs scored and four RBI in a 6-5 win in extras.

LaRoche has homered in three straight games and has four homers over his last three games. He has gone 4 for 11 with four runs scored and seven RBI during that three-game span.

Nationals reliever Drew Storen entered Friday's game in the 10th inning with a one-run advantage.

The right-hander worked his way around two hits as he secured a 6-5 victory. He struck out one and improved his ERA to 4.41 after notching his first save of the season.

Nationals pitcher Rafael Soriano was unable to hang on to a late lead as he blew his second save of the season Friday night against the Padres.

Soriano, who entered the game in the ninth with a two-run lead, surrendered a run-scoring single to Chase Headley and a run-single to Kyle Blanks that tied the game. Soriano, who also picked up the win, has allowed three runs and six hits over his last three innings of relief.

Nationals pitcher Gio Gonzalez enjoyed a solid performance but did not factor into the decision Friday night against the Padres.

Gonzalez, who made his ninth start of the season, surrendered two runs in the first inning and a solo home run to Jedd Gyorko in the sixth for his only damage of the night. He was charged with three runs -- two earned -- and six hits over 6 2/3 innings of work. He struck out five and walked three in a 6-5 win in extras.

Gonzalez has allowed a home run in four of his last five starts. He has surrendered just four earned runs over his last 19 2/3 innings of work. He is scheduled to make his next start Wednesday at San Francisco. He is 1-1 with a 3.38 ERA in his last three starts at AT&T Park.

Nationals starting pitcher Ross Detwiler underwent a second MRI Friday after suffering back spasms in Wednesday's start.

Manager Davey Johnson told reporters Detwiler will not make his scheduled start Monday at San Francisco. The team has yet to release the results of his latest MRI, which could indicate if his injury will require a trip to the disabled list. The first test showed an "irregularity" in the right side of Detwiler’s back, Johnson told The Washington Post.

Detwiler is 2-4 with a 2.76 ERA in eight starts for the Nationals.
