Nine Young MLB Hitters Who Benefited From Better Swing Decisions In 2020

1. Austin Riley, 3B, Braves
Age: 24

The bottom-line progress Riley made in 2020 was modest—he hit .239/.301/.415 with eight home runs and batted seventh in a stacked Braves’ lineup during the postseason—but his plate skills showed encouraging growth. In his second big league season, Riley chased less often and dramatically improved his rate of zone contact. Those are encouraging trends for a young slugger who ranked as the Braves’ No. 1 prospect heading into 2019.

2. Rowdy Tellez, DH, Blue Jays
Age: 26

It’s not entirely the Vlad and Bo show in T.O. The emergence of comparatively unsung young hitters such as Tellez, Teoscar Hernandez and Cavan Biggio helped propel the Blue Jays to third in the American League in runs scored in 2020. For Tellez, maintaining the plate skills growth he showed in 2020 will be essential to remaining relevant in a stacked Toronto lineup that now includes free agent imports George Springer and Marcus Semien.

3. Raimel Tapia, OF, Rockies
Age: 27

Tapia led off for the Rockies more often than any other player in 2020 and compiled a .370 on-base percentage when batting first. Underscoring his breakthrough were marked improvements to his chase rate and zone contact rate. Tapia’s overall walk rate remains modest, but then again good things happen when batters put the ball in play at Coors Field. Tapia’s fantasy relevancy hinges on those hits continuing to fall, along with the runs scored and stolen bases that are more plentiful out of the leadoff spot.

2020	206	96	43	61	37

 

4. Willi Castro, SS/3B, Tigers
Age: 24

Castro didn’t do much with a month of playing time in Detroit as a 22-year-old callup in 2019, but that changed in his follow-up season, one that culminated in a fourth place finish for American League Rookie of the Year. The switch-hitting Castro still chased out of the zone with regularity in 2020, but he made more contact when committing to pitches in the zone. As a result of those better swing decisions, his power output soared and he steadily climbed the Detroit batting order.

2020	140	150	33	49	55

 

5. Austin Slater, OF, Giants
Age: 28

Slater stretches the definition of “young,” but like many Giants hitters in 2020, he authored his best work in the 60-game season. Was it a result of improved coaching? Changes to Oracle Park’s wind patterns? A result of playing a summer-only schedule? Time will tell. But Slater’s combination of power, speed and patience make him worthy in daily lineup leagues, because he enters 2021 as a righthanded complement to outfield regulars Mike Yastrzemski and Alex Dickerson and first baseman Brandon Belt.

 6. Orlando Arcia, SS, Brewers
Age: 26

A series of modest improvements to Arcia’s swing decisions and power output—his average exit velocity also crept above average—resulted in a career year for the rangy shortstop. Still, even with those upticks across the board, he merely reached near-average production. Arcia ranked as the No. 6 prospect in baseball heading into 2016, so he has pedigree. Now the 2021 season will indicate if he has another gear to reach—and if he can escape the lower region of the Brewers’ lineup.

2019	546	62	48	49	42
2020	189	96	52	54	45

 

7. Clint Frazier, OF, Yankees
Age: 26

The time is now for Frazier, the fifth overall pick in the 2013 draft who has a clear shot at playing time in the Bronx for the first time this season. A plus barrel rate and improving chase rate that now borders on plus-plus both portend good things, though below-average contact in the zone will keep Frazier’s strikeout rate high. 

	PA	wRC+	O-Swing	Z-Contact	Barrel
2019	246	107	62	42	60
2020	160	149	69	43	61

 

8. Jeimer Candelario, 3B/1B, Tigers
Age: 27

Candelario had a track record of hitting for average and drawing walks in the minor leagues, but he was a .223 hitter in the majors entering 2020. After improving his swing decisions and looking to do damage, Candelario broke out last season with career bests for batting average (.297), strikeout rate (23.8%) and barrel rate (10.3). He batted fourth for the Tigers in his final 30 games and put up a .910 OPS in that time. Candelario is projected to hang onto his cleanup batting position at least through Opening Day.

2020	206	136	52	56	56

 

9. Trent Grisham, OF, Padres
Age: 24

Drafted 15th overall out of high school by the Brewers in 2015, Grisham toiled in the minors for a few seasons before his 2019 breakthrough at Double-A and Triple-A carried him to a big league callup. Milwaukee traded him to the Padres that offseason after an uneven rookie season. Grisham made across-the-board improvements in 2020, fueled by plate discipline and impact progressions, and stands poised to lead off for the Padres’ potent lineup this season.

2020	252	121	64	51	58
