CHICAGO -- Before Thursday's game, Cubs manager Joe Maddon was asked whether he has been more impressed by Addison Russell's offense or his defense this season. Russell answered for his manager with two outs in the seventh inning, smacking a two-run single to lift the Cubs to a 5-4 victory over the Giants and spoil Jeff Samardzija's return to Wrigley Field.
"He's growing up as a Major League baseball player," Maddon said of Russell after he delivered his 11th game-winning RBI of the season and 10th at home. "His confidence could not be higher."
"I embrace those situations," Russell said. "In that situation, I didn't try to do too much. I just wanted to see a pitch and go about my approach the same way."
Samardzija was making his first start as a visiting pitcher at Wrigley, which was once his home turf.
"It was an exciting atmosphere and it reminded me a lot of my earlier years here, when we were filling it up," said Samardzija, a Cub from 2008-14. "It's still different being on the other side, but it was fun."
The Giants' right-hander survived a shaky first inning, throwing 47 pitches and giving up three runs, including one on Bryant's RBI single, which extended the Cub's hitting streak to 14 games. In the next three innings, Samardzija threw 40 pitches combined. Manager Bruce Bochy then called upon his bullpen, and did so often, using four pitchers in the seventh inning alone.
"We just couldn't tack on," Bochy said. "That's the difference. Their 'pen did quite a job on us."
This was the first of four games between two teams that could meet again in October. The Cubs began the day with a 15-game lead in the Central Division, their largest on Sept. 1 in 109 years, while the Giants are on top of the NL Wild Card standings despite going 11-16 in August. San Francisco trails first-place Los Angeles by two games in the NL West.
MOMENTS THAT MATTERED Keep the line moving: The Cubs made Samardzija work from the start, beginning with a 13-pitch at-bat by leadoff man Fowler that resulted in a walk. Fowler moved up on a wild pitch and then scored on Bryant's soft single to right. The Cubs now have scored in the first in six consecutive home games. They weren't finished either. Heyward tied the game with an RBI single and one out later, Chris Coghlan lined an RBI double down the right-field line for a 3-2 lead. The Cubs have outscored opponents, 93-56, in the first.
Fowler's at-bat was key.
"When your leadoff hitter does that, it sets the tone," Maddon said.
Basic offense: The Giants rediscovered the joys of putting the leadoff batter on base. Each time that happened, they scored. Unfortunately for them, they accomplished this only during the first three innings. Denard Span doubled to open the game and set up Hunter Pence's two-run homer off Cubs starter Mike Montgomery. Joe Panik was grazed by a pitch to start the second inning and came around to score without benefit of a hit. Demonstrating the respect he commands, Buster Posey drew a third-inning walk before tallying the run that gave the Giants a temporary 4-3 edge.
Pence rejected the notion that the Giants' aim was to excel down the stretch.
"If you only come to play in September and October, you're missing out on a lot of the season," he said. "You have to keep getting up there and having at-bats with intention."
Start me up: In his third start for the Cubs, Montgomery gave up four runs -- three earned -- over four innings. The lefty has been subbing for John Lackey, who is expected back in the rotation on Sunday. But Montgomery could start again. The Cubs are considering using a six-man rotation in the final month of the regular season to conserve the starters.
Nice recovery: This may sound strange, but Samardzija actually pitched capably after his dreadful first inning. Beginning with his strikeout of Montgomery to end the first, Samardzija retired eight consecutive batters and 10 of the final 12 he faced. Bochy removed him after he yielded three runs and five hits in four innings, marking only the third time this season that he couldn't last at least five innings.
Samardzija, who also drove in a run with a sacrifice fly, said that he's "always upset" when he can't pitch deep into a game and give the bullpen a break.
"It's unfortunate we had to burn through seven guys on your day," he said, including himself in that total.
