The Chicago Cubs made a series of trades and signed No. 2 overall pick Kris Bryant in July.

"It's been a great month for the Cubs," Theo Epstein said. "Right now, it's a good time for people who are wanting things to go well and looking for progress to seize onto it."

However, Epstein doesn't want to get ahead of himself.

"It's an important time to remind everyone and ourselves that the progress won’t be linear," he said.

"There are going to be other really bad months. There are going to be prospects who go through difficult months, half-seasons and seasons. And you think, 'Hey, you thought these guys were going to be impact guys, and now they're scuffling. What's going on?' There are going to be times we have really difficult times in the big leagues. Unfortunately, just like a player's development, the progress of an organization isn't always linear."
