WASHINGTON (AP) -- Scott Olsen was as good at the plate as he was on the mound.

Olsen had a double, a single and an RBI, all while taking a two-hit shutout into the sixth inning Tuesday night and helping the Florida Marlins beat the Washington Nationals 9-3 to improve to 2-0 for only the second time in their 15 seasons.

At least the Nationals can take solace from this: No one got hurt.

Before the game, Washington put two starters on the 15-day disabled list because they were injured during Monday's 9-2 loss to Florida -- center fielder Nook Logan (left foot) and shortstop Cristian Guzman (left hamstring).

So Washington called up Kory Casto, who never had played above Double-A, and started him in the outfield in his first major league game. Josh Wilson started at shortstop -- his first big league action since appearing in 11 games with Florida in 2005 -- and made one of the Nationals' two errors.

For five scoreless innings, Olsen (1-0) looked much better than he did during spring training, when he was 1-4 with a 4.63 ERA, or the last time games counted, when he went 0-3 with a 4.03 ERA in his final five starts of 2006.

He wound up lasting 5 1-3 innings Tuesday, charged with two runs, two hits and five walks.

Nationals starter Shawn Hill (0-1) got into trouble right away in his first appearance in the majors since June 28. The right-hander needed 18 minutes and 36 pitches to get through the first inning alone.

The game began with Hill hitting Hanley Ramirez with a pitch. Then Dan Uggla hit a grounder that Wilson dived to stop, but the shortstop's attempt to shovel the ball to second with his glove went awry, leaving both runners safe. After Miguel Cabrera walked to load the bases, Mike Jacobs' grounder hopped under first baseman Dmitri Young's glove and through his legs for an error that allowed two runs to score.

That drew the first boos of the night from the crowd of 20,894 -- about half as many as opening day.

Miguel Olivo added a two-run single in the first to make it 4-0, and Florida could have tacked on more, but Alejandro De Aza grounded into the first of three double plays Hill would get.

Hill, who missed all of 2005 after elbow ligament replacement surgery, gave up Olsen's double to right on the second pitch of the second inning, followed by Cabrera's RBI single. But then Hill settled down and was lifted for a pinch-hitter after allowing five runs -- four earned -- and five hits in five innings.

He did hear some jeers after popping up a bunt attempt while batting in the third. There were other miscues by the Nationals, including in the sixth, when reliever Ray King loaded the bases on two singles and a walk.

That brought up Olsen, whose grounder to first appeared to set up a double play. But after Young threw to second for one out, King failed to cover the bag at first for a return throw. So that allowed another run to score, making it 6-0.

Washington scored twice without the benefit of a hit in the sixth after Olsen walked the bases loaded and was lifted, leaving the mound muttering. Left-hander Renyel Pinto walked Young to force in a run, and Brian Schneider's sacrifice fly made it 6-2.
