Dontrelle Willis and Roy Halladay were as good as usual. The Washington Nationals are a lot better when they play at home.

Willis and Halladay had their latest impressive performances, but the surprising Nationals opened a nine-game road trip with their most lopsided loss of the season, falling 11-1 to the Los Angeles Angels on Monday night.

Washington had won 10 straight games, tying a franchise record, to finish a 12-1 homestand. The NL East-leading Nationals are 24-9 at RFK Stadium, but lost for the sixth time in their last seven road games and fell to 13-18 away from home.

Paul Byrd allowed four hits and one run in six innings, and the Angels had a season-high 20 hits against Esteban Loaiza (2-5) and two relievers. Vladimir Guerrero went 4-for-4 with a three-run homer and drove in five runs.

"We did a lousy job tonight pitching to him and a few of the other hitters," Nationals manager Frank Robinson said.

Florida and Toronto had no troubles with their pitching.

Willis (11-2) became the majors' first 11-game winner, allowing one run in seven innings to lead the Marlins to a 9-1 victory over the Chicago Cubs. He added two hits and drove in a run in Florida's seven-run fifth inning.

"He's the stopper, the savior and everything else," Marlins manager Jack McKeon said. "I don't care whether we start him or DH him."

Halladay was even sharper, pitching a five-hitter for his major league-leading fifth complete game, and the Blue Jays beat the St. Louis Cardinals 4-1.

Halladay (10-3) has won six of his last seven starts and lowered his ERA to 2.33. The 2003 AL Cy Young winner leads the league in innings pitched (108) and is tied for the league lead in wins.

"He's having some kind of year," Toronto manager John Gibbons said. "He's in an elite class and that's what those kind of pitchers do."

Halladay has rebounded after winning only eight games while battling a shoulder injury in 2004. He was dominant against a St. Louis team that has lost just four of its last 22 interleague games.

"I don't think film does Halladay justice," Cardinals shortstop David Eckstein said. "You don't understand how hard he's throwing the ball with that much movement."

Jeff Suppan (5-6) allowed three runs and eight hits in seven innings.

At Chicago, Willis got the Marlins off to a strong start on a 12-game, four-city road trip, their longest this season. He has already surpassed his win total from last season, when he went 10-11.

Miguel Cabrera, Paul Lo Duca and Alex Gonzalez each drove in two runs for the Marlins.

"It was a big game for us today, starting off the road trip," Willis said. "We came ready to play."

John Koronka (1-2) gave up six runs and seven hits with three walks in 4 1-3 innings.

At Boston, Manny Ramirez hit a three-run homer and Matt Clement (7-1) rebounded from his only loss of the season in the first meeting of the teams since the 1975 World Series.Boston scored nine runs off Eric Milton (3-8), who matched his career high for runs allowed, set in 2002 against Cleveland.

At St. Petersburg, Fla., Jonny Gomes and Travis Lee homered to back Doug Waechter (3-3), helping Tampa Bay to consecutive victories for the first time in more than two weeks.Prince Fielder, son of former major league star Cecil Fielder, made his big league debut for Milwaukee after being promoted from Triple-A Nashville. The Brewers' first-round pick in the 2002 draft went 0-for-4.

At Arlington, Texas, Alfonso Soriano homered twice against Tim Hudson (6-5), and the Rangers beat the Braves for the first time.Chris Young (6-3) pitched seven shutout innings with seven strikeouts and one walk while allowing just two singles.

At Chicago, Shawn Estes (5-4) pitched his first nine-inning complete game since 2003, and Luis Gonzalez and Troy Glaus hit consecutive home runs off Jose Contreras (3-3) during a six-run second inning for Arizona.Chicago's Frank Thomas homered in the fourth inning, then limped off the field with a cramp in his left leg after singling in the sixth. It wasn't immediately know how serious the injury was.

At Baltimore, Jay Gibbons and Larry Bigbie homered in a six-run second inning, and the Orioles ended the Astros' five-game winning streak.Orioles rookie Hayden Penn (1-0) earned his first big league win despite allowing five runs and seven hits in 5innings.
