DENVER -- Josh Fogg knew he was throwing the ball well. He just didn't have much to show for it until Sunday.
"Sometimes there's nothing you can do," Fogg said. "You want to go out there and win every game, but that just isn't possible."
It was the fourth series sweep of the season for Colorado, which matched its best start after 44 games. The Rockies also started 25-19 in 1995.
"You'd love to win 25 games, but realistically that isn't going to happen," Fogg said. "When you get a big lead, you have to go out there and throw up zeroes to let the offense go back and score some more runs."
Fogg (3-2), who hadn't won since beating Arizona on April 13, allowed three runs and seven hits over 5 2/3 innings. He had given up 20 earned runs in 34 2/3 innings over his previous six starts.
"He loves to compete and he had good stuff," Colorado manager Clint Hurdle said. "He tried to exploit some weaknesses that we thought he could do, and he did exploit them and used his fastball on both sides of the plate."
Fogg scattered three hits through four innings before allowing singles to Gregg Zaun and Eric Hinske to open the fifth. One out later he was ahead of Alex Rios 1-2, before Rios turned on a slider and hit the pitch into the seats in left for a three-run homer to make it 5-3.
"He was tough on us," Toronto manager John Gibbons said. "He didn't give us much and we didn't capitalize enough when we did get scoring chances."
Fogg left after giving up a two-out double to Zaun in the sixth. Tom Martin came in and retired pinch-hitter Reed Johnson to fly out to center field.
Brian Fuentes worked the ninth for his 10th save in 11 chances.
Toronto's Ted Lilly (4-4) allowed five runs and six hits in 1 2/3 innings. He struck out one and walked two.
"This was a very poor performance," Lilly said. "I looked up at the scoreboard after the second out of the inning and I had thrown 80 pitches and that's ridiculous."
Colorado took a 2-0 lead in the first inning. Eli Marrero and Clint Barmes each drove in a run with bloop singles with the bases loaded.
Atkins cleared the bases with a double in the second inning to make it 5-0.
"I got a pitch that I could hit and hit a line drive to the gap," Atkins said.
The Blue Jays were swept for the first time this year. Toronto has lost three in a row for the first time this season.
