Mike Trout is the best baseball player on the planet.
The 29-year-old has been one of the game's elite since exploding on to the scene with 10.5 WAR during his rookie season in 2012. He is having arguably the best season of his career right now as the MLB leader in on-base percentage (.477), slugging (.673) and OPS+ (219) with 2.1 WAR in 32 games.
In the middle of his prime, Trout is showing no signs of slowing down, but there will inevitably be a point in the future when his production starts to decline and someone else takes up the mantle of baseball's best player.
Who will that someone be?
We ranked the 10 most likely candidates to supplant Trout as the best player in the game, based on impact tools, current production and future outlook.
10. SS Jordan Lawlar
Looking for a wild card in the future best player in baseball conversation?
Look no further than Texas prep shortstop Jordan Lawlar, the favorite to be selected No. 1 overall in the 2021 draft.
"Lawlar is a more polished hitter than [Bobby Witt Jr.] was at the same stage with a quick, compact right-handed swing and a mature, patient approach," according to MLB.com.
He still needs to work on slowing the game down when he's in the field, but with 60-grade speed and quick-twitch athleticism, there is no reason to think he won't stick at shortstop.
Andrew McCutchen was a bona fide superstar and squarely in the best player in baseball conversation during his prime, so going No. 1 to the rebuilding Pittsburgh Pirates would not necessarily hinder Lawlar's future.
He could have a major impact on MLB in the not-too-distant future.
9. RF Mookie Betts
Will there be a window for Mookie Betts to be baseball's best player?
The Los Angeles Dodgers star is one year and 61 days younger than Mike Trout, so the outfielders are on similar trajectories.
With one MVP Award, two runner-up finishes and 47.2 WAR in eight MLB seasons, Betts is on a Hall of Fame path and regularly mentioned as one of the game's elite.
It's simply a matter of unfortunate timing that Betts isn't higher on this list, as he will likely share the spotlight with Trout for the entirety of his career.
8. CF Luis Robert
The Chicago White Sox paid $26 million and a matching tax penalty to sign Luis Robert out of Cuba in 2017.
That investment looked like money well spent when he hit .328/.376/.624 with 31 doubles, 11 triples, 32 home runs and 36 steals while reaching Triple-A in 2019, and he took MLB by storm last year.
A late slump cut into his numbers, but he still finished with a 100 OPS+ and 11 home runs in 56 games to finish second in American League Rookie of the Year voting while also taking home a Gold Glove Award in center field.
The five-tool player was showing a more refined approach early this season, trimming his strikeout rate from 32.2 to 27.2 percent while hitting .316/.359/.463 through 25 games before suffering a torn right hip flexor that will keep him sidelined for three to four months.
Robert will lose valuable developmental time, but he still has the chance to become a superstar and the face of a dynamic young roster.
7. 1B Vladimir Guerrero Jr.
Vladimir Guerrero Jr. was saddled with lofty and perhaps unfair expectations when he made his MLB debut in 2019 shortly after his 20th birthday.
He posted a 109 OPS+ with 2.7 WAR over 183 games in his first two seasons, and despite the fact that he's still younger than many of the game's top prospects, some were foolish enough to call him a bust heading into this season.
Now it's all clicking.
Guerrero is hitting .307/.432/.543 for a 176 OPS+ that ranks seventh in the American League, and settling in at first base should give him a chance to focus on the offensive side of his game.
With nearly as many walks (25) as strikeouts (26), Guerrero has displayed the hit tool that earned him a rare 80 grade from MLB.com during his prospect days, and he is still just scratching the surface of his power potential.
He could be this era's Miguel Cabrera.
