"Today, I was a little bit more relaxed and I just stayed with my approach and it worked out for me that first at-bat," said Russell, who batted .318 in 11 games with Triple-A Iowa before his promotion.
"It feels really good to get that first one out of the way," said Russell, who finished 1-for-4 in the Cubs' 4-3 loss to the Pirates. "We'll just have to see where we go from here."
In his debut, Russell, 21, went 0-for-5 with three strikeouts. He can relax. In Kris Bryant's big league debut last Friday at Wrigley Field, he went 0-for-4 with three K's.
"I think it's a good stepping stone for the future," Russell said. "I can build off this and see where it takes me."
