CHICAGO -- The Chicago Cubs broke out of their recent offensive slump in a big way in a 7-2 victory over the Miami Marlins on Saturday night at Wrigley Field. Here’s a quick look at the game:

Holiday fireworks: The Cubs planned a Fourth of July fireworks show for after the game, but Kris Bryant had other ideas. The rookie slugger put on a fireworks show of his own well before dusk by blasting a pair of home runs in the first two innings to stake the Cubs to a big early lead.

In the first inning, Bryant crushed the first pitch he saw from Marlins starter Jarred Cosart (1-4) over the left-field bleachers and onto Waveland Avenue for a 2-0 lead. Then in the second, with two out and the bases loaded, he cranked a 3-1 pitch from Cosart (a 96 mph fastball) into the left-field bleachers for a grand slam and a 7-0 lead.

Bryant, who now has 12 homers, is the first Cubs rookie to hit two grand slams -- the other was on June 17 at Cleveland -- since Billy Williams in 1961. It also was Bryant’s second multihomer game of the season. The first came on June 22 against the Los Angeles Dodgers at Wrigley. Bryant also has 49 runs batted in to take over the team lead in that category.

Strong return: If not for Bryant’s rockets, the big story would have been the triumphant return to the major leagues by left-hander Clayton Richard, who was impressive in his first start since 2013. Richard (1-0) allowed two runs on eight hits in 6⅓ innings.

Richard’s last major-league appearance was on June 21, 2013 with the San Diego Padres. He left that start against the Dodgers after throwing just two pitches and soon underwent acromioclavicular (AC) joint surgery. Then in February 2014, he had thoracic outlet surgery. He missed nearly all of the 2014 season before making his debut on Aug. 10 in the minor leagues.

This season, Richard made 10 starts in the Pittsburgh Pirates’ minor-league system before he was traded to the Cubs on Friday for cash considerations on Friday.

Mr. 2,000: For what it’s worth, Richard -- who spent parts of six seasons with the Padres and Chicago White Sox -- is the 2,000th player to appear in a game for the Cubs.

Next: Right-hander Kyle Hendricks (3-4, 4.15 ERA) goes for the Cubs in the finale of the three-game series against right-hander Mat Latos (3-5, 5.27). In his last start, Hendricks threw six shutout innings against the New York Mets. In the two starts before that, he had allowed a total of 10 runs in 10 innings in a pair of losses to the Minnesota Twins and the Dodgers.
