Together, those things brought an end to Philadelphia's five-game winning streak.
Tulowitzki homered and had three hits in his Blue Jays debut as Toronto trounced the Phillies 8-2 on Wednesday night.
"Tonight is about Tulowitzki," Phillies interim manager Pete Mackanin said. "What a great first impression."
Tulowitzki, a five-time All-Star who was acquired Tuesday in a trade with the Colorado Rockies, went 3 for 5 with two doubles and three RBIs. He scored three times.
"It couldn't have gone any better, really," manager John Gibbons said.
Dickey (5-10) allowed two runs, none earned, and seven hits in eight innings to win consecutive starts for the first time this season.
"If he's got his knuckleball working, nobody hits him," Mackanin said. "Tonight he had a good one. That's not the kind of guy you want to see when you're swinging the bats well. He can put everybody in a slump."
The Phillies lost for the second time in 11 games since the All-Star break. Toronto has won nine of the past 10 meetings with Philadelphia.
Right-hander Jerome Williams (3-8) allowed four runs and matched a season-high by giving up 10 hits in 4 2-3 innings. He's 0-6 with an 8.02 ERA in nine road starts.
"He threw too many hittable pitches," Mackanin said. "He was OK, he just wasn't sharp."
Williams has allowed at least one home run in each of his past six starts.
"You just have to take it and come back next time," Williams said
Catcher Carlos Ruiz acknowledged that it's not easy mapping out a game-plan against the Blue Jays, who lead the majors in runs.
"They have a very good lineup," Ruiz said. "For the pitcher, you have to hit the corners of the plate. It's hard when you make a mistake with a lineup like that."
Tulowitzki was cheered when he came out for pregame stretching and got a standing ovation before his first at-bat, stepping out briefly to let the noise subside.
"The ovation from the crowd that first at-bat was obviously special," Tulowitzki said. "I think it made my at-bat that much harder."
After working the count to 2-2, he struck out swinging on a breaking ball.
Starting in the leadoff spot for the first time in his career, Tulowitzki connected for a two-run home run off Williams in the third. The second-deck blast, Tulowitzki's 13th, came on an 0-2 pitch and snapped an 0-for-21 slump.
"That was huge for me to get that under my belt," he said. "I relaxed after that and took better swings."
Tulowitzki doubled and scored in the fifth, then hit an RBI double in the sixth before scoring on Chris Colabello's sacrifice fly.
The two-time Gold Glove winner showed off his defense, making a strong throw from the hole to retire Andres Blanco at second in the third.
"On both sides of the ball he looked really good," Gibbons said. "But he is really good."
ROAD RUN OVER
The loss snapped Philadelphia's season-high four-game road winning streak.
Toronto designated LHP Felix Doubront for assignment to clear a roster spot for Tulowitzki. Doubront was 1-1 with a 4.76 ERA in five games.
Blue Jays: 1B Edwin Encarnacion (left middle finger) was scratched from the lineup and replaced by Colabello. X-rays were negative. ... Jose Bautista (right hamstring) was the DH but is expected to return to the outfield Thursday. ... 2B Devon Travis (left shoulder) was held out of the lineup and replaced by Ryan Goins. Travis will be evaluated again Thursday.
Phillies: Philadelphia returns home Thursday to begin a four-game series against Atlanta. RHP Aaron Harang (4-11, 4.08 ERA) faces Braves RHP Shelby Miller (5-7, 2.27 ERA) in the opener. Harang has lost his past eight decisions and is winless since May 14.
Blue Jays: Toronto begins a four-game series against AL-best Kansas City on Thursday. RHP Marco Estrada (7-6, 3.55 ERA) faces LHP Danny Duffy (4-4, 4.03) in the opener. Estrada lost a matchup with Duffy on July 10, allowing two runs in 6 2-3 innings.
