"It's huge," Peterson said.
"You look at the guys that are around the infield, and the defense as a whole, it's hard not to be excited about that group.

You see statistically they're at the top of every list."
The Cubs believe Peterson will benefit from their defensive positioning and analytical infrastructure, especially given his career 51.5 percent groundball rate.
This transition marks the first time Peterson has changed organizations in his 10-year professional career.
"When I was there, my whole goal and focus was to help the Mets win games," Peterson said.
"But I do think there is something to that. I've seen it with other guys.
I've seen it with friends in the game where they're kind of stuck in a rut or stuck in a spot that they're not necessarily enjoying, and they've gone somewhere else and had a lot of success.
That's part of what gives me excitement about this opportunity."
Cubs manager Craig Counsell endorsed the move, noting that a new environment often provides a necessary spark for struggling players.
"We all can acknowledge that sometimes a change of scenery is a good thing," Counsell said.
"When things aren't going well, sometimes a fresh start is something that can kind of reenergize you, refocus you, and hopefully get you to a good place.

Hopefully, we can provide that."
