5) Nolan Arenado’s 2016 season (Age 25 season)
By WAR, Arenado’s 2016 season was better but they are so close and because of the higher offensive production that he had in 2016, I’m going with this in a slot higher.
Arenado played in 160 games and he had 116 runs, 182 hits, 35 doubles, 41 home runs, 133 RBI, 68 walks, 103 strikeouts, a slashline of .294/.362/.570, a 129 OPS+, and 13 DRS.
His WAR was 5.9 for this season and that’s mainly because of his Defensive Runs Saved. It went down from 22 to 13. His offense (OPS+) went up five percent so that’s why we have this season ranked higher.
4) ) Troy Tulowitzki’s 2009 season (Age 24 season)
While Troy Tulowitzki is just making his debut on this list at number four, this is not his only time on here.
In 151 games in 2009, Tulowitzki scored 101 runs, had 161 hits, including 25 doubles, 32 home runs, 92 RBI, 20 stolen bases, a slash line of .297/.377/.552, an OPS+ of 131.
The Rockies made the playoffs this year and Tulo’s regular season was a big reason behind it. He hit .250 (4-for-16) in the NLDS that year as the Rockies were dispatched in 4 games by the reigning World Champions and future NL Champs, the Philadelphia Phillies.
