Gavin, the son of former Oriole slugger Larry Sheets, showed great plate discipline during his three years with Wake Forest. After hitting a combined 11 homers in his first two seasons, his junior year saw him turn it up a notch as he hit 21. That year with the Demon Deacons, Sheets slashed .317/.424/.629 in 63 games with those 21 homers, 10 doubles, 46 walks (15.6%) and just 37 strikeouts (12.5%). With numbers like that, it was no wonder that the White Sox selected him in the second round of the 2017 draft. After the draft, combined with the AZL squad and Kannapolis to slash .279/.365/.397 in 56 games with 12 doubles, four homers, 28 RBIs, 23 walks (9.8%) and 34 strikeouts (14.5%).
Against stronger competition in 2018 with Winston-Salem, Sheets produced similar numbers to the year before. In 119 games totaling 437 at-bats, Sheets slashed .293/.368/.407 with 28 doubles, two triples, six homers, 61 RBIs, 52 walks (10.5%) and 81 strikeouts (16.3%).
Just like his junior season, however, Sheets turned his power up a notch in his third professional campaign. In 126 games totaling 464 at-bats, of which half were spent at pitching-friendly Regions Field, he slashed .267/.345/.414 with 18 doubles, 16 homers, 83 RBIs, 54 walks (10.2%) and 99 strikeouts (18.8%) for Birmingham. His numbers would’ve been even better, if not for a difficult April in which he slashed just .207/.286/.293.
MLB Pipeline give Sheets 50 grades for his power, hit and fielding tools while giving him a 55 for his throwing arm. The site also says of him, “The White Sox believe more home runs will come as he starts incorporating his legs more in his left-handed swing and makes an adjustment to stop hooking balls foul down the right-field line. He has a smooth stroke and controls the strike zone well for a big man, so he should hit for average and draw a healthy amount of walks.”
Sheets will be expected to get the lion’s share of Charlotte’s first base duties in 2021, and his success there may well determine his role going forward. With Andrew Vaughn now also in the picture, Sheets will also be vying with players like Zack Collins and (perhaps) Yermín Mercedes for the 1B/DH role in 2021. Another wrinkle in his South Side future is Sheets’ ability to man a corner outfield position, which he began working on in earnest last summer, when the White Sox chose to bypass him for alternate site Schaumburg workouts.
