Despite a highly successful season, Kris Bryant is at home while the season winds down for the Chicago Cubs.

"I think now more than ever, I'm realizing this game is a business, and all I can do is go out there and play as hard as I can and make it really hard on the guys in charge," Bryant said. "I think I did that this year. If I'm taking that mindset, then I'm not really going to be sitting there with my head down at the end of the year."

Service time issues and 40-man roster spots are helping prevent the top prospect in baseball from playing in the Major Leagues. The Cubs called up seven less-heralded players on Tuesday.

"It's kind of funny, all the rules," said Bryant, who led the minor leagues with 43 home runs this season. "Coming into professional baseball, I had no clue. I didn't pay any attention to it in college, either. At the end of my first season, I kind of know the lingo about all this stuff. I guess the system works in some ways, and in some ways there are some flaws. I can't focus on that. I've always been high on avoiding the distractions."

He proved a lot this year between Double-A and Triple-A, putting up 110 RBIs, a .325 batting average and a .438 on-base percentage.

"Next year, I'm really looking forward to coming out with a little chip on my shoulder," Bryant said. "I'm going to go out there looking to prove something."
