CHICAGO | Rookie Randy Wells won his fourth consecutive start, Derrek Lee homered and the Cubs got their sixth win in eight games, beating the Atlanta Braves 4-2 on Monday night.

Wells (4-3) gave up seven hits and two runs in six innings, including a homer to Nate McLouth. Kevin Gregg worked the ninth for his 15th save in 18 chances.

Jair Jurrjens (6-7), who held the Phillies hitless for 6 2/3 innings in his previous start, gave up four runs and seven hits in six innings, including Lee's 16th homer, a two-run shot in the first.

Cubs third baseman Aramis Ramirez returned to the lineup after missing two months with a dislocated left shoulder and got a loud ovation in his first at-bat. He went 0-for-4.

Jurrjens had given up only six homers all year before Lee drove a pitch deep into the left-field bleachers in the first -- one out after a leadoff single by Kosuke Fukudome -- to give the Cubs an early cushion.

The Cubs tacked on two more in the second with four consecutive two-out hits. Mike Fontenot and Wells singled, Fukudome lined an RBI double into the right-field corner and Ryan Theriot beat an out an infield single to short as Wells scored for a 4-0 lead.

Atlanta had three singles off Wells in the fourth, including an RBI liner to center by Escobar that cut the lead to 4-1. And when Wells' fumbled Casey Kotchman's dribbler to the left of the mound for an error, the Braves had the bases loaded. Wells escaped by striking out Matt Diaz and getting Jurrjens to hit into a forceout.

McClouth led off the fifth with his 14th homer -- fifth since joining the Braves -- to cut the lead in half.
