Outfield Tiered Ranks - 5x5 Mixed Leagues (December)

In case you missed it, our very own "Big Pick Nick" Mariano was named the #1 overall most accurate industry expert ranker for the 2018 season.

Tier One

Be sure to also read part two of our outfield rankings analysis, tiers 6-13.

After years of sitting in a tier of his own, Mike Trout finally has someone to challenge him as the undisputed number one player for fantasy baseball. It's a neck and neck race for me personally between the reigning AL MVP and Ronald Acuna Jr., but I give the edge to the latter for a couple of reasons.

If it wasn't for a small groin strain in the final week of the regular season, we may be talking about Acuna Jr. being the first 40/40 player since 2006. He finished three steals shy of this prestigious club after clubbing 41 homers in 156 games, and he would have been the youngest player ever to join at age-21. It's also easy to believe that Acuna Jr.'s 127 R, 101 RBI, and .280 BA have potential for more with natural progression in the league and an excellent lineup around him.

Despite winning the AL MVP for the third time in 2019, Trout is coming off his third consecutive injury-shortened season. He's proven he doesn't need to play a full 162 games for owners to benefit, but the fact that he's averaged 129 games played since 2016 is a bit concerning. Trout's 11 thefts in 2019 also tied a career-low, and I wouldn't be surprised if he finished in single digits in 2020 to help limit the injury risk. We're splitting hairs at the top of the rankings board, but give me Acuna Jr. for the upside 5x5 production.

Mookie Betts' slow start to the 2019 season left owners disgruntled, but his year-end numbers ended up surprisingly comparable to his 2018 MVP campaign. He led the league in runs for the second consecutive year (135), which was six more than the year previous. Betts also matched his RBI output (80) last season while finishing three homers shy of his 2018 mark with 29 HR. His .295 BA and 16 steals lagged, but if these numbers resemble a floor for the recently turned 27-year-old, he's a safe first-round selection no matter who he plays for in 2020.

Tier Two

Tier two is a small drop off in fantasy talent, mainly because of the lack of elite speed for these power bats. Juan Soto has the youngest legs of the bunch, and has arguably the most potential heading into the new decade. His 34/110/110/12/.282 roto line is salivating for a player who just turned 21-years-old during the World Series, and there's still room for growth. His 20.0% K-rate and 16.4% walk rate are also commendable for such a young bat, making the ceiling sky-high for "Childish Bambino."

J.D. Martinez is a player I'm a bit higher on than my fellow rankers. It's clear he had a step back from his remarkable 2018 season, but a 36/98/105/2/.304 season is nothing to scoff at either. His BABIP was unusually high in his first year in Beantown (.375), so his BA dropped .026 points last season when his more genuine .342 BABIP fell near his lifetime mark (.346). Martinez also had an expected batting average (xBA) of .309, which was ninth-best in the majors, and he set a career-high in K-rate with a 21.0% K%. Batting in a hitter-friendly division and as a part of the potent Red Sox lineup, I'll gladly take Martinez' mix of reliable power and average.

On the flip side, Bryce Harper is a player that is lower on my list. While he nearly put together his second straight 100 R and 100 RBI season, his lack of production in the BA category downgrades him from the rest of the outfielders in this group. After hitting .260 last season, the $300 million man has eclipsed this mark just once since 2015, and his plate discipline metrics keep trending in the wrong way. Harper's K-rate dropped for the fourth consecutive season to 26.1%, the lowest mark since his rookie campaign, while his 68.3% contact rate and 15.1% SwStr% finished at bottom-seven levels league-wide. I'm more bearish than most on Harper, even with his improvement in the second half.

Tier Three

Charlie Blackmon continues to put up sterling fantasy numbers aided by his favorable home ballpark. In 2019 he slashed .379/.435/.739 at home compared to .256/.299/.432 away from Coors Field, and for his career, the results aren't much different. These vast splits are something I tend to stay away from when drafting a player, but after Blackmon's longevity at producing at a high rate, he's hard to ignore. He did, however, steal just two bases last year, so it appears he's becoming a four-category contributor.

Starling Marte quietly had his best all-around season in 2019 despite playing just 132 games. He set career-bests in HR (23), R (97), and RBI (82), while posting an admirable .295 BA with 25 SB. Good health has always eluded Marte, but he's a reliable 5x5 contributor when he's on the field.

Yordan Alvarez is an impressive hitter that I'm more bullish on, and one who could catapult himself into a first-round value after the 2020 season. The AL Rookie of the Year had a phenomenal 87 games clubbing 27 dingers and 78 RBI while slashing .313/.412/.655 as the primary fourth or fifth batter for the Astros. Alvarez notably struggled in the postseason after seeing a heavy dosage of breaking balls, but he started to adjust in the World Series with a more disciplined approach. In the regular season, however, the 22-year-old's top-10 Barrel% (17.2%) was no fluke as he's mashed at every level of ball coming through the farm system. "Air Yordan's" talent is for real, and his teammates don't need to bang on a garbage can for him to prove it.

After stealing 45 bases in 2018, Whit Merrifield's 20-SB total last season was dissatisfying to say the least. His 2020 outlook doesn't appeal to me either as he enters his age-31 season with new manager Mike Matheny, whose Cardinals teams from 2012-17 finished 29th overall in thefts.

Tier Four

An injury-shortened season capped what could have been a career year across the board for Joey Gallo in 2019. His elite 52.3% Hard Hit%, 26.4% Barrel%, and 150-game pace (47/116/105/9/.253) would have all finished as career-highs, making the 26-year-old a potential draft-day steal with his stock currently underpriced.

After years of getting stashed away in the Pirates system, Austin Meadows emerged into the fantasy limelight with the Rays in 2019. Swiping 12 bases with 83 runs and 89 RBI in 138 games, the All-Star surprised the most by swatting 33 big flies. Meadows never hit more than 12 home runs in any minor league year, but his 17 round-trippers over the final two months of the season suggests he's figured out his power stroke. He achieved this feat by pulling nearly 14% more of his fly balls in the second half, a recipe for tremendous home run success. Look for Meadows to put up huge numbers in 2020 with a full healthy season.

Eloy Jimenez had a productive debut campaign in the majors with a 31/69/79/0/.267 roto line in 122 games for the White Sox this past season. Despite his tremendous success, his inclination to hit the ball on the ground makes me more bearish on the former Cubs prospect. His 47.9% GB% was over 5% higher than the league average, and only one other player with this many worm-killers was able to hit more than 30 homers last season (Jose Altuve). Jimenez also struggled to hit breaking balls and off-speed pitches with an xBA of .220 and .226, respectively. The 22-year-old has a bright future ahead of him, but I won't be paying for his name at face value in 2020 drafts.

Tier Five

Fantasy players have waited years for Jorge Soler to develop a premium big-league bat, and 2019 was finally the year he stayed healthy and put it all together. His full 162 game season helped him lead the AL in homers (48) while finishing tied for second in RBI (117) and fifth in SLG (.569). Like Jimenez, Soler struggled to hit anything other than a fastball, which aided his 26.2% K% to fall in the AL's bottom-10. Although when he did make contact, it was to a top-10 finish in Hard Hit% (49.9%). It almost seems ludicrous to have this kind of power bat ranked so low, but Soler needs to put together another healthy and productive campaign before he can climb the board.

Once Nicholas Castellanos got some lineup protection with the Chicago Cubs, he transformed into a second-half MVP candidate. His 37 extra-base hits led baseball in the final two months while he finished second among outfielders with 43 runs. As long as Castellanos doesn't land in Miami this offseason, he'll produce 25-30 HR and 180 R+RBI with ease.

Many analysts, including myself, believed Andrew Benintendi would produce a profitable 5x5 roto line in 2019, but his results were nothing short of disappointing. The 25-year-old took a step backward in his third major league season, hitting .266 with 13 HR, 72 R, 68 RBI, and 10 steals. All of these numbers were career lows after he began the year as the team's leadoff hitter before getting ultimately moved down as the Red Sox fifth hitter in the second half. His second straight 40-double season was laudable, but it appears that's more his niche, and we shouldn't expect a ceiling higher than 20 HR.

Yasiel Puig continues to put up middling numbers, but yet his draft value seems to elevate every season. He's averaged 25/69/74/16/.265 over the past three campaigns, which doesn't equate to a top-100 pick for me. Puig's potential landing spot this offseason could bump him up a few ticks, but he failed to produce at a higher rate in 2019 even with an improved home ballpark.
