TORONTO -- Roy Halladay would have tried for the shutout during his Cy Young season two years ago -- before a right shoulder injury in 2004 forced him to be more careful.
Halladay led the AL with 266 innings and tied for the lead with nine complete games in 2003, but he won just eight games in 2004 after the troublesome right shoulder limited him to 21 starts.
"It's always icing on the cake to get a shutout, but I think you've got to be smart," Halladay said. "We learned a lot of stuff last year. We're trying to be as smart as we can."
Halladay (7-2) allowed four hits and lowered his ERA to 2.84. He struck out two and walked two for his sixth win in eight starts.
The 28-year-old right-hander retired the last 13 batters he faced. He threw 98 pitches, 64 for strikes. Scott Schoeneweis and Justin Speier completed the four-hitter, Toronto's fourth shutout of the season.
"I'll feel rested going into the next one. I'm happy about that," Halladay said.
Hinske homered off Tony Armas (1-2) in the sixth, his first homer in 61 at-bats. He has five this season.
"I want to hit home runs, man," Hinske said. "But I've been getting my hits. I haven't felt bad at the plate. I just haven't been getting the ball up into the air."
Washington's Brad Wilkerson robbed Hinske of extra bases by crashing into the wall in left-center to make a catch in the eighth.
"He made a great catch. It's one of the best catches I've seen in a while," Hinske said.
The Nationals have scored just two runs in their first two games back in Canada. After playing in Montreal as the Expos from 1969 through last season, Canada's first major league baseball team moved to Washington during the offseason and was renamed.
"Halladay had all his pitched working for him," Washington's Nick Johnson said. "When you get your pitch you can't miss it."
Toronto rookie Aaron Hill had two hits and is 4-for-8 in his first two major league games.
Toronto's Orlando Hudson went 3-for-4 with an RBI and two runs scored.
Hudson led off the bottom of the first with a double, and scored on Alex Rios' RBI triple.
Hill hit an RBI double in the second and Hudson added a run-scoring single to make it 4-0.
"It's tough when you give Halladay four runs to work with," Armas said.
Hudson tripled in the seventh and scored on Frank Catalanotto's RBI single, giving Toronto a 7-0 lead.
Armas allowed seven runs on 10 hits in seven innings.
- Toronto C Gregg Zaun, who was hospitalized after sustaining a concussion while breaking up a double play last week, went 1-for-3 with a double and a strikeout in rehab start at Double-A New Hampshire. Zaun is expected to come off the 15-day disabled list on Tuesday.
- Washington RHP John Patterson, bothered by back spasms, won't make his scheduled start Sunday. RHP Tomo Ohka will take his turn in the rotation.
- Toronto's Russ Adams ended a 0-for-19 slump with a single in the eighth.
