Kyle Schwarber, Jason Heyward and Anthony Rizzo all homered by the fourth inning, and Cueto's rough month continued to a 4-1 loss to the Cubs that evened the four-game series at two wins apiece. Cueto allowed four runs in six innings, all on the homers, in a confounding start. The first pitch was delayed by 1 hour, 5 minutes after it rained so hard, manager Bruce Bochy and general manager Bobby Evans already were discussing whom they might promote for the 26th man for the nightcap of a Wednesday doubleheader, which is now allowed. After Cueto struck out Ben Zobrist to start the first, Schwarber blasted his seventh homer of the year over the right-field bleachers and onto Sheffield Avenue. An inning later, Heyward lined a ball that barely cleared the basket in right for his fourth homer and a 2-0 Cubs lead. Rizzo's two-run homer in the fourth gave the Cubs a 4-0 lead. Even with that affliction, eight of the 14 runners who have tried to steal on Lester have been caught, a combination of his quickness to the plate and Willson Contreras' arm.
