In Anthony Rizzo's age-25 season, he put up an .899 OPS in the majors, finishing 4th in MVP voting and hit two homers in the NLDS series victory over the Cardinals.
In Matt Mervis' age-25 season, he put up a sub .600 OPS and failed to beat out the likes of Trey Mancini and Nick Madrigal for playing time, resulting in him being sent down for his fourth look at Iowa.
I'm not exactly worried we're gonna miss the boat on this one.
