Anthony Rizzo hit a grand slam in Chicago's eight-run fifth inning, and rookie Addison Russell homered twice in a game for the first time in his career to power the Cubs and Jon Lester to a 14-5 rout of the Arizona Diamondbacks on Friday.
Javier Baez added a two-run shot -- his first homer this season -- and went 3 for 4 in his third game since his recall from the minors as the Cubs rolled to their third win in five following a four-game losing streak.
Rizzo's 28th homer was his second career grand slam. Russell has three homers in his past four games and 12 this season.
Lester (9-10) was staked to an early lead and rebounded after being hit hard in two of three prior starts. The left-hander's command wasn't razor sharp, but it was good enough as he allowed two runs on five hits in five innings before four Cubs relievers finished.
Jake Lamb hit a two-run homer for the Diamondbacks, who have lost nine of 12.
Arizona rookie starter Zack Godley (4-1), recalled from Double-A Mobile prior to the game, lost for the first time after solid performances in three previous major-league starts -- including two six-inning outings when he didn't allow a run.
The former Cubs propect struggled with control in this one, walking six while allowing six runs on four hits in 3 2/2 innings. He walked in two runs as Chicago jumped ahead 3-0 in the first with just one bloop single.
Diamondbacks reliever A.J. Schugel also walked in a run while allowing being tagged with seven in Chicago's big fifth inning.
Lester gave up five runs, including four in the seventh, last Saturday in a loss to the Dodgers in Los Angeles. On Aug. 19, he lasted just 2 2/3 innings and allowed seven in a loss to Detroit.
Between those two outings, the lefty came within one out of pitching his first complete game and shutout as a Cub in Chicago's 2-1 win over Cleveland on Aug. 24.
Russell led off the second with his first homer, a solo drive, to make it 4-0.
After Arizona cut to 4-1 in the fourth, Russell's two-run shot in the bottom half made it 6-1.
Rizzo and Baez both connected in the fifth as the Cubs sent 11 men to the plate and pulled away.
