CHICAGO -- There it was, another big at-bat staring at Addison Russell. And once again, the young star delivered.Russell hit a two-run single with the bases loaded in the seventh inning, and three relievers combined for five perfect innings to lead the Chicago Cubs to a 5-4 victory over the San Francisco Giants on Thursday night.Hes growing up, manager Joe Maddon said. As a major league baseball player, his confidence could not be higher.The Cubs spoiled a shaky Jeff Samardzijas return to Wrigley Field and started September on a winning note after going 22-6 to match the 1932 team for the best August in franchise history.The major league leaders also moved a season-high 39 games over .500 and a jaw-dropping 15 1/2 games ahead of St. Louis in the NL Central -- their largest lead in the standings since the 1907 team finished 17 games ahead of Pittsburgh, according to the Elias Sports Bureau.Russells bloop single off Cory Gearrin gave the Cubs a 5-4 lead. Dexter Fowler had two singles and scored two runs.Kris Bryant added an RBI single to extend his hitting streak to 14 games, matching a career high. And the Cubs rallied behind a dominant bullpen and another big hit by Russell.I kind of embrace those situations, he said. In that situation, I didnt try to do too much. I just wanted to see a pitch, really, and just try to go about my approach the same way.The 22-year-old Russells 88 RBI are tops among National League shortstops. He is 8 for 18 and has driven in 23 runs with the bases loaded. On top of that, he is playing a Gold Glove-level defense.His go-ahead hit wiped out a 4-3 deficit and capped a rally that began when Hunter Strickland (3-2) gave up a leadoff single to Fowler and walked Bryant after two close pitches were called balls.Will Smith walked Ben Zobrist with one out to load the bases before retiring Jason Heyward on a pop fly. But Russell then drove in Fowler and Bryant with a bloop single to left.It obviously felt like I had a good game plan, Gearrin said. Made two good pitches and broke his bat and he just found a hole. Its just frustrating because you want to get the result no matter what. At the same time as a pitcher, you can only do so much.That made a winner of Joe Smith (2-4), who worked two innings after returning from a strained left hamstring.Carl Edwards Jr. worked the ninth for his first career save with Aroldis Chapman getting the night off after pitching in the previous three games. And the Cubs came away with the win on a cool and windy night in which both starting pitchers lasted just four innings.SHAKY STARTSSamardzija gave up three runs and five hits, walked three and threw 87 pitches in his second start against Chicago and first as a visitor at Wrigley Field.
