Woah, it's Nelly! Not only is it befittingly his Twitter handle, it's the exact phrase the South Atlantic League, its scouts, the Marlins' organization and anyone who follows it are exclaiming regarding James Nelson's season to date. One look at the stats including his absolutely unprecedented month of May, it's easy to see why.

Nelson was born on October 18, 1997 in Rex, GA and attended Redan High School in nearby Stone Mountain. Other than the budding Nelson, Redan is famous for producing MLB talents such as Wally Joyner and Brandon Phillips. As Nelson relates to, Redan is a place that is very proud of that past and their long-tenured heritage and Raiders players, including Nelson, coaches and parents quickly learn that. Rahter than just being part of for four years, they are part of a brotherhood forever.
After his graduation in 2015, Nelson was selected by the Red Sox in the 18th round of that year's Draft. However, Nelson forwent signing with Boston to attend junior college in Cisco, Texas in an attempt to raise his draft stock.
Despite his great high school tenure, Nelson only hit four total home runs in his junior and senior seasons. In his one year at Cisco, a bulked up Nelson hit 17. After going off the board 531st overall a year prior, some scouts had Nelson going off the board as early as round 12. The Marlins selected Nelson with the 443rd overall pick in round 15 thus making his decision to attend Cisco a success. This time, Nelson forwent the rest of his college career to sign a pro contract at the age of 19, another big choice and another one he and his family does not regret.
Upon his arrival in the professional ranks last season, Nelson supported evidence that he was indeed ready to make the jump. In 43 games in the Gulf Coast League, he hit .284/.344/.364. His BA ranked 15th in the league and his OBP ranked 20th. Among his impressive countable stats were 24 RBI and a 7/3 SB/CS. Despite appearing at the plate just 162 times, the Marlins were impressed enough to promote Nelson to full season ball at the ripe age of 19, 2 1/2 years younger than the average Sally League player. After a bit of a feeling out process in his first eight games in April when he hit .207/.324/.345, Nelson absolutely exploded in May, responding and rewarding the Marlins' vote of confidence by becoming one of the best hitters in the league and a sure-fire choice for the upcoming All-Star Game. His ridiculous month of May consisted of a .372/.425/.540 slash line along with 8 doubles, a triple, 3 homers, 17 RBI and a 5/1 SB/CS. Overall this season, Nelson's .338 BA ranks third in the Sally, his .404 OBP ranks fourth and his .500 SLG ranks ninth. He ends the month of May riding a 17-game hitting streak.
So how has this teenager with just a year's worth of college experience and 43 games worth of pro experience under his belt, responded so well to playing against the best competition that he ever has gone up against while being under the pressure and microscope that goes along with being regarded as the club's 10th best prospect and how will he keep it up over the course of a 140 game season, three times as many games as he's ever played in in a single year? Simple: he won't change a thing and most importantly, he will not get too far ahead of himself. Because after all, whatever level you're at and wherever you are or aren't ranked within the organization, the game remains the same.
If there was a knock on Nelson's offensive game from his days in the GCL it was his production against lefties which he hit at just a .231/.286/.269 clip. This season, again, against much more advanced competition, he has remedied that by hitting southpaws at a .388/.492/.694 pace. Once again, Nelson credits what he believes is the end-all, be all, vision. After that, it has been his ability to stay inside the ball a lot more consistently that has made the difference.
Nelson has accomplished all of these offensive accolades over the past two years while also learning how to play a new position, third base, where the Marlins believe his growing frame, plus power and strong arm will be better suited in the long run. While learning the hot corner has been and will continue to be a process for Nelson, he doesn't mind; as long as he's on the diamond.
Nelson's at-bats are a sight to behold. After the 6'2" specimen stares down his opposition from a straight vertical stance, he times his swing with a front leg trigger that is less reminiscent of a batter and more so of a pitcher. From there, there's only one word to describe him: explosive. Stretching his arms all the way back for as much power as possible while somehow maintaining extremely good balance and very rarely, if ever, falling off to either side of the plate, Nelson's bat is barely recognizable as it whips through the zone with uppercut action. After exhibiting some of the best bat speed within the organization, he stays through the ball with two hands on the bat and two eyes down all the way and looks the ball off the barrel, keeping him from pulling off. Mechanically, everything looks close to perfect for the still-maturing Nelson, making him a near lock to become a 20+ home run hitter. While on base which Nelson has been a ton this season, he has more than above average speed, especially for a guy his size. Add to that the ability make great reads and you have the acumen of a 20+ base stealer. As a GCLer in 2015, he stole seven bags and was caught three times. In less games this year, he has already swiped five while being caught just once.
If there has been one consistently below-average area of Nelson's offensive game throughout his career it's been his ability to walk, common for any power-first hitter but not an area which Nelson is willing to go to the wolves. He has proven that by walking more in less ABs this season compared to last season and which he hopes to improve even further by advancing and utilizing his plate vision, no matter the situation.
Nelson will be the first one to admit he is far from a finished product and he has work to do. However, the 19-year-old who will not even turn 20 for another two months, defines the word 'athlete', has a baseball IQ well beyond his years, and is already on the verge of a call-up to A+. With 20/20 club type talent, the ability to hit for both average and power and great fielding instincts, footwork and hands, he is a 5-tool type talent that could arrive in the majors as early as 2019. But for now, the extremely modest and level-headed Nelson ins't worried about that.
Keep doing you, James. If baseball is crazy, you've found the remedy.
