CHICAGO (Ticker) -- Jeromy Burnitz suddenly found some success with the bases loaded, an experience that Joey Devine is not familiar with.

Burnitz blasted a grand slam off Devine in support of Jerome Williams ' 7 2/3 impressive innings as the Chicago Cubs rolled to a 10-1 victory over the Atlanta Braves .

A career .212 hitter with the bases loaded, Burnitz had been even less successful this year, managing just one hit in 11 at-bats with the bags full.

However, the veteran outfielder made those numbers more respectable in the fifth with one swing of the bat when he blasted the second pitch he saw from Devine over the center field wall for his eighth career grand slam.

"I definitely, for the last week, felt I was getting better at-bats up there," Burnitz said. "I'm getting some better pitches to hit and definitely feeling more comfortable in the box."

"I kind of went over it on tape," Devine said. "The pitch I threw (Burnitz) didn't sink the way the one that I previously thrown to him. He put some pretty good wood on it."

Atlanta's first-round pick in 2005, Devine made a rapid ascent through the minor leagues, but has not fared well in two major league appearances.

The 21-year-old righthander took the loss in his major league debut Saturday when he surrendered a grand slam to San Diego's Xavier Nady in the 13th inning of a 7-2 loss.

Combined with Tuesday's effort, the righthander has a 31.50 ERA through his first two career outings.

"The biggest thing for me is to keep learning and try to make my pitches," Devine said. "This game can definitely bring you down if you let it and that is definitely not the direction I'm going in. I'm going to continue to learn from my mistakes."

Chicago's 15-hit attack provided more than enough support for Williams (4-6), who yielded just one run and three hits to win for the first time in five starts. The righthander, who entered just 1-for-17 at the plate this season, aided his own cause with a double in the third and a single in the fourth, with each hit igniting a four-run rally.

"Quite frankly, (Williams) hasn't looked too good at the plate since we got him," Cubs manager Dusty Baker said. "Jerome got us going tonight with his bat and his pitching. He really picked us up."

Neifi Perez had a two-run single in the third and Michael Barrett added a two-run double in the eighth for the Cubs, who snapped a three-game losing streak.

Braves starter John Thomson (3-4) allowed five runs, seven hits and three walks in just 3 2/3 innings. The veteran righthander is 0-2 with a 10.83 ERA in three starts since returning from a three-month stint on the disabled list with a strained finger.

"I don't know what it is," Thomson said. "Sometimes it just doesn't go your way. You make good pitches, they get hits. Sometimes you leave balls over the middle of the plate and they pop them up. It's just the game of baseball and you have to deal with it."

Andruw Jones belted his major league-leading 40th home run in the fifth for Atlanta, which has lost five of its last eight games.
