The biggest jump in a prospect card’s value usually comes when he is first called up to the majors. For some players though, it takes a little bit longer to catch on and establish themselves as big leaguers. However, I can’t track all these players forever, there has to be a cutoff point. This is how I came up with the Rookie+1 designation.
Rookie+1 means that after a player is called up for the first time, the value of his first Bowman Chrome autograph card will be tracked for one full season after he exceeds his rookie eligibility. This way, a player loses their prospect designation after being called up to the expanded roster, filling in for injuries, or whatever other reason, they won’t be punished for it. All call ups will be tracked for at least two full seasons. These first two seasons are when a player’s card values fluctuate the most. While it is certainly possible for players to break out after their sophomore year, for the most part it possible to have a general sense of who a player is after two years.
With all that in mind, below is a list of eleven former prospects that are entering the +1 year of their Rookie+1 status. At the end of the 2021 season, they will be retired off MJR’s list of call ups. Over the next few months leading into spring training I will take a closer look at each player, their performance thus far, and the general feelings of each player within the card collecting hobby. Some, like Kyle Lewis and Luis Robert, have already proven their worth. Others have a little more to prove, like Carter Kieboom and Gavin Lux. Be sure to check back here every Wednesday for the latest update and follow along on social media to let us know who you’re hoping for a big season from. There is a lot on the line for players and collectors a like. And so in the immortal words of Woody Harrelson in Zombieland, “It’s time to nut up or shut up.”
