Bryce Harper won the NL MVP Award on Thursday. A player called baseball’s “Chosen One” when he was only 16 years old, Harper fully happened in 2015, staying healthy enough to play in 153 games and setting new career highs in practically every offensive category.

Here are 7 incredible facts about Harper’s 2015 season:

1. It was the best offensive season since Barry Bonds retired

Harper put up the type of numbers we haven’t seen much of in recent years, with pitchers dominating the Majors. Harper’s 1.109 OPS is the highest mark since Albert Pujols’ MVP 2008 campaign. But in context, Harper’s 195 mark in park- and league-adjusted OPS+ stands as the best season since Barry Bonds retired. And Barry Bonds, lest you forget, was an otherworldly hitter.

2. No player his age has hit so well since Ted Williams

Harper became one of only three players ever with an OPS+ of 190 or higher at age 22 or younger. The others? Ted Williams and Ty Cobb. Ted Williams! Ty Cobb! Bryce Harper!

3. He raised his career OPS+ over 20 points

Harper entered the season with a very good 121 career OPS+. He finished it with a 143 career OPS+. To put that in context: In the course of one year, he went from Harold Baines to Harmon Killebrew. And smart money says it’ll keep climbing from here.

4. He showed way better plate discipline

Harper has credited his breakout campaign to his health, and it could be that staying on the field and getting more reps allowed him to work counts better and get better pitches to drive. But by whatever means he got there, Harper made an astonishing improvement. He entered the season with a 10.4% career walk rate, then walked in 19% of his plate appearances in 2015. Unsurprisingly, he also hit more line drives, more home runs and more extra base hits than ever before.

5. Only two other players his age have gotten on base so much.

Harper led the Majors with a .460 on-base percentage. It was the third best OBP ever for a player at age 22 or younger. The only players Harper’s age to ever post higher OBPs? Ted Williams and Jimmie Foxx. This is a theme: Harper had the type of season typically only seen by inner-circle Hall of Famers when they’re his age.

6. He became one of only seven players his age to hit 40 homers

This time a couple non-Hall of Famers sneak onto the list, but one of them is A-Rod and the other, Juan Gonzalez, likely would have got there if his career weren’t derailed by injuries by his early 30s. The others: Eddie Mathews, Mel Ott, Joe DiMaggio, and Johnny Bench.

7. He finally faced a pitcher younger than him

Until June, Harper had gone his entire professional career without facing a pitcher younger than him — including in his minor league rehab stats. Harper didn’t turn 23 until mid-October, and he’s already arguably the best hitter in the world. Buckle up, folks.
