WASHINGTON (AP) -

Matt Garza was knocked out in the first inning of his shortest major league start, and Ryan Zimmerman and Wilson Ramos drove in three runs apiece to lead the Washington Nationals over the Milwaukee Brewers 8-3 Saturday night.

Garza (6-7) faced eight batters and got just one out, allowing four singles, a double and two walks in the shortest of his 211 big league starts dating to 2006. His previous low was 1 1-3 innings at the Marlins on June 18, 2010, according to STATS.

Garza had been 4-2 with a 2.35 ERA in his previous eight outings, but Saturday's effort caused his season ERA to rise from 3.69 to 4.04. He dropped to 0-3 with a 7.33 ERA in six career starts against the Nationals.

Tanner Roark (9-6) gave up one runs and six hits in seven innings with five strikeouts. In his first full season as a starter, he has allowed two earned runs or fewer in 13 of 19 outings.
