The summary

The Cubs, playing the first of their 38 final games against playoff contenders, leaned on a two-run home run in the first inning by Anthony Rizzo, his 29th of the season and his second in as many games. Tsuyoshi Wada put a runner on base in each of the first four innings but escaped each time.

The game was delayed by rain before the Cubs batted in the bottom of the fifth. Grounds crew workers had difficulty covering the infield as a torrential downpour flooded the infield and some outfield areas. About one hour, 40 minutes after the delay, crew chief Hunter Wendelstedt and managers Rick Renteria of the Cubs and Bruce Bochy of the Giants inspected the infield before grounds crew workers applied more drying compound to the shortstop area. Nearly one hour later, the field was inspected again. After the inspection, the infield was dragged by grounds crew workers, with an emphasis around the shortstop area. The game was eventually called after a four-hour, 34-minute rain delay.

At the plate

Javier Baez drew a walk on a 3-2 count before Rizzo hit his home run but took a 92 mph fastball for a called third strike in the third.

On the mound

Wada struck out counterpart Ryan Vogelsong to strand Joaquin Arias in the second.

In the field

Shortstop Starlin Castro lost the grip while transferring the ball from his glove to his hand, resulting in an infield hit for Arias with two outs in the fourth.

The number

69: speed, in mph, that Wada threw to Buster Posey in the third inning.

The quote

Renteria: “We certainly have to minimize any kind of mistakes we make playing contending teams. There ‘s a reason why they’re contending. A combination of skill and playing the game a certain way. I’ll be honest. I’m very happy with the way we’ve continued to play the game, even against some of the better clubs.”

Up next: Giants (Peavy 2-12, 4.57) at Cubs (Jackson 6-13, 5.74), 7:05 p.m., Wednesday, WCIU-26.
