Chapman was solid with the bat for the surprising Athletics, but he's on this list because he was baseball's best defensive player by a wide margin. The 25-year-old's 29 defensive runs saved led the majors, and he was the lone third baseman with an ultimate zone rating above 10.

Baez finally broke out at the plate this year, emerging as the Cubs' best hitter in 2018 with 83 extra-base hits and an NL-best 111 RBIs. He also continued his trademark stellar defense - at three different infield positions, to boot.

Ramirez made history as the fourth player ever to tally at least 100 walks, runs, and RBIs as part of a 30-30 season. He also dramatically improved his defense at third base before shifting to second in September. He's a perennial MVP candidate for a reason.

Arenado's all-around brilliance pushed the Rockies to the playoffs for a second straight year. In addition to winning another Platinum Glove as a defender, he led the NL in homers (38) for the third time and was top-10 in several other offensive categories.

After breaking out in 2017, the 24-year-old attained superstar status in '18, emerging as one of the AL's top hitters with a flair for the dramatic and penchant for showmanship. He led the majors in doubles, had 11 more walks than strikeouts, and was named All-Star Game MVP.

The Red Sox paid Martinez to hit baseballs - and that he did, leading the league in total bases and RBIs while ranking top-3 in each slash-line category and homers during a near-Triple Crown campaign. He was named the AL's top offensive player.

Ohtani lived up to the hype and became MLB's first true two-way player since Babe Ruth, crushing 22 homers in over 300 PAs as a DH while averaging 11 strikeouts per nine with just six HRs allowed in 10 starts on the mound - all while battling an elbow injury.

He fell one RBI and two homers shy of a Triple Crown, but no matter. Yelich cruised to the NL MVP with an incredible season that saw him lead his league in batting, slugging, OPS, and total bases. He hit for the cycle twice (against the same team) and ranked top-10 in virtually every meaningful category.

Ho-hum - just another all-time great season for Trout. In an injury-shortened campaign, he still led all hitters in OBP, OPS, OPS+, and walks. He finished six steals shy of a 30-30 campaign, scored over 100 runs, saved eight runs defensively, and was an MVP finalist for the sixth time since 2012. Don't take his greatness for granted.

Betts produced a 30-30 season and led the league in runs, batting, slugging, and WAR. He played award-winning defense in right, hit a career-best 47 doubles, and won a World Series ring. He was the best player in baseball on the best team in baseball, and has the hardware to prove it.
