Isaac is a rare premium first base prospect. Most of the best fantasy first basemen were underrated as prospects (Paul Goldschmidt, Pete Alonso) or came up at other positions (Bryce Harper, Vladimir Guerrero), but the Rays selected Isaac out of high school with the No. 29 overall pick in 2022 knowing full well he'd be splitting time between first base and designated hitter. The 6-foot-4, 240-pound lefty slugger has huge raw power, but he didn't sell out for it in his first full pro season, logging a 21 percent strikeout rate at Single-A and at High-A. His walk rate was eerily consistent as well, (15% at Single-A, 14% at High-A). Anyone who doubted Isaac's game power got a swift lesson at the end of the year after he hit six home runs in 12 High-A games en route to a .490 ISO in that brief run as a 19-year-old. Isaac could be big-league ready in a year or two, and the main question is whether he will be platooned at the highest level. He had a .976 OPS and 20.1 K% in 339 plate appearances against righties and a .697 OPS and 25.5 K% in 94 plate appearances against southpaws. Read Past Outlooks
