He could've used some help in the fifth. The D-backs had a runner at first and one out when A.J. Pollock hit a grounder to shortstop Starlin Castro who flipped the ball to Addison Russell. But Russell bobbled the ball, and was charged with an error, and everyone was safe. One out later, Arrieta walked Paul Goldschmidt to load the bases and David Peralta cleared them with a double.
"He misread it," Cubs manager Joe Maddon said of Russell. "All he had to do was get one out. There was no double play and he's thinking double play, and that's one where you just have to have that internal clock to work, 'I'm not getting two outs, just get one, get off the bag and don't get hurt.' That's what happened, that's all that happened."
Arrieta talked to the rookie infielder, who is making the transition from shortstop to second at the big league level.
"Obviously, he's extremely talented and I think he's our youngest player," Arrieta said of Russell, who is the youngest in the National League at 21. "He's got so much room to grow and those are things he'll have to go through and we'll have to go through as a team to get better. I told him, 'Hey, [Anthony] Rizzo put us on his back, he picked everybody up, let's learn from that.' At the end of the day, it was a win."
Rizzo drove in six runs, including three on a game-winning home run with one out in the ninth.
