CHICAGO -- Jason Heyward's return to the Chicago Cubs lineup will have to wait another day.
The game against the Milwaukee Brewers on Saturday afternoon was rained out. It will be made up at 1:20 p.m. CT on July 6.
"Nothing you can do about (the weather), that's why we're here to embrace the suck," said Cubs manager Joe Maddon, referencing the team's new T-shirt slogan.
Heyward was on Maddon's lineup card after a stint on the disabled list since May 8 because of a sore knuckle on his right hand.
Heyward is hitting .253 with three homers and 17 RBI. He was scheduled to bat sixth and play right field on Saturday.
Chase Anderson (2-0, 3.43 ERA) and Jake Arrieta (4-3, 5.44) will pitch on Sunday.
Rookie Ian Happ was to return to Saturday's lineup in center field, batting fifth.
"Like a lot of our guys, he's not overwhelmed and that's probably the most impressive part of it, he's acting like he wants to stay and that he belongs here," Maddon said.
Happ, the No. 9 overall draft pick from 2015, was 7 for 21 for a .333 batting average with two homers and four RBI in six games. He was called up from Triple-A Iowa on May 13.
"I'm starting to get a feel for the first time playing in the outfield with these guys consistently," said Happ, who played mostly second base in spring training. "(Wrigley Field) is what I heard about. One day you get the wind blowing out, and you can flick home runs. The next day, you hit the ball as hard as you can and it's caught before the track. It's Wrigley, it evens out, and it makes the game interesting, for sure."
Maddon also had Kyle Schwarber moved down to second in the lineup after batting leadoff all season. Second baseman Ben Zobrist replaced him at the top.
Schwarber is batting .182 with a .305 on-base percentage with six home runs and 17 RBI.
"We talked about Kyle hitting a lot of balls into that shift," Maddon said. "If (Zobrist) can get on base a little more often, it might move that second baseman out of that spot."
The manager would not commit to the change for Sunday.
