Burroughs' first homer since '05 lifts D-backs over Nats

Now, that's an unlikely hero.

Sean Burroughs hit his first home run in more than six years to lift the Arizona Diamondbacks over the Washington Nationals, 2-0, in the second test of a four-game series.

Burroughs' two-run blast in the seventh inning was his first since April 30, 2005. Coincidentally, that homer came against Arizona when he was as a member of the Padres.

Ian Kennedy (16-4) also played a key role in snapping Arizona's six-game skid. The right-hander gave up six hits during seven scoreless innings. He struck out eight and walked two while becoming the National League's first 16- game winner.

The Diamondbacks, who lead the Giants by 1 1/2 games in the NL West, made a trade before the game, acquiring second baseman Aaron Hill and infielder John McDonald from the Toronto Blue Jays in exchange for second baseman Kelly Johnson.

The news was not all great on Tuesday for the D-backs. Outfielder Justin Upton left the game with a left elbow contusion after being hit by a pitch.

Washington starter Jordan Zimmermann (8-11) allowed two runs on five hits over 6 1/3 innings. He struck out four and walked two.

The start of the game was delayed by 21 minutes because of an earthquake that rattled the East Coast earlier in the day. The epicenter of the quake was near Mineral, Virginia -- about 36 miles northwest of Richmond and 88 miles southwest of Washington, DC.
