Willson Contreras had a Memorial Day to remember as he established new career high marks in home runs and RBIs to pace Triple-A Iowa in an 11-0 win against Albuquerque.

Contreras, the Cubs' No. 2 prospect, hit a pair of home runs, including a grand slam, en route to driving in five runs in his second four-hit game (4-for-5) of the season for the Cubs. He also scored three runs in the contest.

Contreras' first homer of the afternoon didn't come until the bottom of the sixth inning, when he blasted a grand slam to right-center field off Isotopes reliever Ryan Carpenter in his second at-bat of the frame. He singled in his first at-bat and the Cubs ultimately scored 10 runs in the inning.

"Especially when you start the inning with a base hit, then you come up again with the bases loaded, I was just trying to put the ball in play," Contreras told MiLB.com. "I wasn't trying to hit a grand slam, but it happens."

He went deep to the opposite field once again in the eighth inning, this time tagging Sam Moll for a solo shot. Baseball's No. 45 overall prospect has hit five homers in his last six games for Iowa, and his eight long balls in 44 games this season match his output from his 126-game breakout campaign at Double-A Tennessee in 2015.

Overall, Contreras is hitting .329/.418/.559 with 20 extra-base hits and 30 RBIs this season and has shown that his Southern League batting title (.333) last year was no fluke.

"I'm happy with everything. I'm happy with the team, with doing everything we've been doing," he told MiLB.com. "I always wake up in the morning thinking about the game, thinking about winning. I'm a baseball player, and that's all I want to do is win games."
