"This is a very exciting day for the Detroit Tigers, Colt, his family and our fans," Tigers president of baseball operations Scott Harris said in a statement. "Colt has done everything we've asked of him during his young career, improving all facets of his game and asserting himself as one of the sport's most promising young players. This contract demonstrates our faith in Colt and this organization's commitment to acquire, develop and retain young talent."

"I couldn't be more excited to reach this agreement, securing my place in this organization for years to come," Keith said in a statement. "Since being drafted in 2020, all the coaches and staff have been invaluable in helping me and my teammates grow on and off the field. There's a reason I felt strongly about making a long-term commitment to be here, and being surrounding by incredibly talented teammates and coaches in a big part of that.

"I'd also like to thank my family, fiancé, agent and friends for their tireless support throughout my life and career. Without them, I wouldn't be where I am today. I know this is a big accomplishment, but ultimately my mission is to be the best player possible and help win a World Series championship for Tigers fans everywhere."
