The nephew of ex-big leaguer Chris Nelson, James turned down the Red Sox in 2015 as a 15th-rounder from a Georgia high school and opted to attend Cisco (Texas) JC. He batted .434/.468/.796 with 17 homers as a freshman, earning him a $75,000 bonus from the Marlins in the 16th round, and earned organization Minor League Player of the Year honors in his first full season. His encore didn't go as well, as he missed the first two months in 2018 after surgery to repair a torn meniscus in his knee and was hampered by nagging hamstring strains afterward.
Nelson makes hard contact to all fields with a short, clean swing from the right side of the plate. Most of his pop in pro ball has come in the form of doubles, but he has the speed and bat strength to develop average home run power. When he tried too hard to hit homers in 2018, however, his stroke got too long and contributed to struggles at the plate.
Nelson has decent speed when healthy but won't be a basestealer. He has the plus arm to make all the throws at third base, though he needs to improve his lateral movement. He has enough tools to become a regular at the hot corner if he can improve his consistency on both sides of the ball.
