Stewart is one of the best pure hitters who hasn't reached Double-A yet. Known as a bat-first third baseman who may move to first base entering the 2022 draft, Stewart showed enough defensive chops in his full-season debut that he may be able to stick at the hot corner long term. He had more walks than strikeouts at Single-A and an equal share (13.7 percent) of walks and strikeouts as a 19-year-old at High-A. Stewart won't sell out for power - his pull% was below 42 percent at both stops - but at 6-foot-3, 215 pounds and with the potential to call Great American Ball Park home, it's conceivable he gets to 25-plus homer power by his mid-20s. Given how safe his hit tool appears, Stewart could break out as a power hitter at any point, and he already appears on track to hit enough to play every day. Read Past Outlooks
