Ronald Acuna

26-Year-Old OutfielderOF
Atlanta Braves
2024 Fantasy Outlook
Acuna went as the No. 1 overall pick in most fantasy drafts last spring and rewarded that faith by filling up box scores every time he stepped on the field. Not only did he join Jose Canseco, Barry Bonds, Alex Rodriguez and Alfonso Soriano as the fifth member of the 40-40 club, Acuna also established the 40-50 club, the 40-60 club and the 40-70 club. It was a historically-great individual season that culminated in a unanimous selection for National League MVP. Some amount of natural regression has to be expected in 2024, but there is no evidence suggesting what Acuna did last year was fluky. He ranked in the 100th percentile in xwOBA, xBA, xSLG and average exit velocity while appearing in 159 of a possible 162 regular-season games for the NL East champions. Maybe the steals won't be fully repeatable -- Acuna ranked in just the 65th percentile in sprint speed in 2023 -- but he's a smart baserunner with a perpetual green light under manager Brian Snitker. Entering his age-26 campaign, the superstar outfielder should again be first off the board in every standard league. Read Past Outlooks
RANKS
$Signed a seven-year, $99.94 million contract extension with the Braves in April of 2019. Contract includes $17 million team option ($10 million buyout) for 2027 and $17 million team option ($10 million buyout) for 2028.
Two more steals before early exit
OFAtlanta Braves
September 30, 2023
Acuna went 1-for-2 with a run scored, an RBI and two stolen bases before being replaced by Kevin Pillar in the third inning of Friday's 10-6 loss to the Nationals.
ANALYSIS
There were no injury concerns with the 25-year-old superstar; he simply got some extra rest with Atlanta having locked up the top seed in the National League playoffs. The steals were the 71st and 72nd of the season for Acuna, and he's now tied with Otis Nixon's 1991 campaign for the third-most in franchise history and the most in the modern era -- only King Kelly's 84 in 1887 and the original Billy Hamilton's 83 in 1896 rank ahead of him.

The baseball world wondered what Acuna would look like coming off his July 2021 ACL tear. Our answer: He remains one of the most dynamic players in the game. There was no easing back into the running game, as Acuna stole two bases in his return from the injured list April 28 and swiped a total of nine bags in his first 20 games of 2022. The dog days of summer were tough on Acuna, and he finished the year with a .413 SLG, over 100 points below his career mark. However, he still ranked in the top eight percent of the league in all of hard-hit percentage, xwOBA and xSLG, per Statcast. His launch angle was down close to eight points from his prior two seasons. Now that he's further removed from the knee surgery, and perhaps with a few tweaks, Acuna should be able to tap into more power and return to the elite tier of fantasy contributors.
Acuna presents quite the conundrum for 2022 fantasy players. He was the top pick in some 2021 leagues and filled the role admirably until an awkward play into the outfield wall in mid-July resulted in a torn ACL. A leg injury for someone whose game features speed is a problem, not to mention the importance of a hitter's lower half in hitting the ball with authority. Acuna is expected to miss the first few weeks of the campaign but could be cleared to serve as the designated hitter by the end of April, with a return to the outfield potentially coming a month later. It could be tough for Acuna to live up to fantasy expectations this season coming off the injury, but his natural talent and abilities can still take him further than most in his situation.
Acuna was a popular pick at number one overall last offseason, and while he didn't finish as the year's best player, it's hard to say he had a disappointing campaign. His .250/.406/.581 line was good for career highs in the latter two categories and led to a career-best 159 wRC+, though his 30-point drop in average was a blow to fantasy players in most formats. His overall output was also held back by the fact that he appeared in just 45 games, missing time due to a wrist issue among other minor ailments. When active, however, the third-year outfielder demonstrated growth in important areas, improving his BB% from 10.6% to 18.8% while increasing his exit velocity from 90.6 mph to 92.4 mph. If his average remains mediocre this season (his .254 xBA suggests he didn't underachieve there), it will hurt his fantasy value by a small amount, but the overall picture here is of a young phenom continuing to grow.
We may now have the answer to the question: "Who else would you draft 1.1 besides Mike Trout?" Acuna Jr., before his 22nd birthday, led all players in fantasy earned auction value last year while nearly pulling off a 40-40 season, slightly edging out Cody Bellinger in overall value. Christian Yelich would have likely won the title had his season not ended prematurely, but the fact Acuna Jr. began 2017 in High-A and ended 2019 as he did is an astounding feat. His barrel rate last season was in the 95th percentile, as was his xSLG and overall offensive production when putting the ball in play. There simply are not enough superlatives to describe what Acuna Jr. can bring to a fantasy roster as he contributes to all five categories and does so exceedingly well in four of them. His deal keeps him in Atlanta for the foreseeable future and health would be the only thing that could derail this production train.
A lot of top prospects fail to live up to the hype. Acuna was not one of them. After receiving the "Kris Bryant Treatment," Acuna got the call to Atlanta on April 25 and ended up returning top-20 value in the outfield in just 487 plate appearances. The incredible bat speed he showed as a prospect manifested itself right away with Acuna hitting for both average and power. His barrel rate of 8.6 Brls/PA was a top-20 mark in baseball (min. 150 batted-ball events), and his recorded sprint speed was also elite. It's incredible to think of what the numbers could have looked like had Acuna not missed a month with a knee sprain. While it's not wise to prorate stats for most players, Acuna is the rare exception with whom it's totally plausible to think he could keep up a similar rate of production over the course of a full season. There is some swing and miss here (25.3%), but Acuna may lead off for the Braves and his physical tools are right up there with the best of the best.
Not only is Acuna the best prospect in baseball, he might be the best prospect to come along since Mike Trout and Bryce Harper were competing for pole position in 2012. It's incredibly rare for a 19-year-old prospect to earn a promotion to Triple-A, but Acuna, who opened the year at High-A, didn't just stop by to get a lay of the land. He was immediately the best player in the International League and was 62 percent better than the league's average hitter (162 wRC+) over 54 games. Dripping with fantasy-relevant tools, Acuna has the speed to steal 30-plus bases, enough power to hit 30-plus homers and the approach and bat-to-ball skills to hit .300. While he didn't show the same patience last year that he did in his first two professional seasons, he will be an OBP monster when appropriate fear is established in the minds of big-league pitchers. Acuna will be promoted to the majors in mid April, once the Braves have secured an extra year of control, and he could be a five-category force from Day 1.
An under-the-radar July 2 international signee out of Venezuela in 2014, Acuna has hit at every stop in pro ball, showcasing high-end tools along the way. He missed 15 weeks in the middle of the season with a thumb injury, but his .819 OPS would have ranked sixth in the Sally League, just behind top Rockies prospect Brendan Rodgers, if he had enough plate appearances to qualify. At 18, he would have been easily the youngest player in the top-10 on that leaderboard, and his 14 steals in just 40 games serve as another separator. The case can be made that on a per-game basis, Acuna was the most impressive hitter in Low-A last year, when factoring in age. He projects to grow into plus power and should maintain above average speed through his prime years, but we won't know what kind of hitter Acuna will be until he gets a taste of quality offspeed stuff at Double-A and Triple-A.
