Player Outlook
Xavier 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.

  • Rays' Xavier Isaac: Returns to action for Bowling Green

    Rotowire
    Isaac (undisclosed) has started in two of High-A Bowling Green's last three games against Asheville, going 0-for-8 with a walk and an RBI. Before checking back into the lineup Thursday, Isaac hadn't played for Bowling Green since June 13 due to an unspecified issue. Despite his two-week absence, Isaac was never placed on Bowling Green's 7-day injured list. The first base prospect is slashing .298/.384/.556 with 12 home runs and 13 stolen bases across 237 plate appearances in the South Atlantic League this season.

  • Rays' Xavier Isaac: Sidelined with undisclosed injury

    Rotowire
    Isaac has not played in a game for High-A Bowling Green since June 13 due to an undisclosed injury. Adam Sanford of DRays Bay looked at the video from Isaac's last game and said Isaac appeared fine during his most recent plate appearance and played two innings more in the field before a defensive replacement took his place. Isaac has not been placed on the injured list. He may have been on the cusp of earning a promotion to Double-A, as he was slashing .397/.480/.730 with four home runs, seven doubles and five steals in his most recent 63 at-bats.

  • Rays' Xavier Isaac: Mashing righties

    Rotowire
    Isaac is slashing .296/.372/.522 with four home runs, three steals and a 26:14 K:BB in 29 games since June 1 for Single-A Charleston. The 6-foot-3 first baseman could end up with 80-grade raw power when it's all said and done, and his 18.2 percent strikeout rate and 15.4 percent walk rate at Single-A are encouraging marks. It's a small sample, but the lefty-hitting Isaac has a .648 OPS in 61 plate appearances against lefties and a .903 OPS in 192 plate appearances against righties. All seven of his home runs have come against opposite-handed pitching.

  • Rays' Xavier Isaac: Dialed in for RiverDogs

    Rotowire
    Isaac slashed .289/.449/.605 with three home runs and five strikeouts in 12 May games for Single-A Charleston. The Rays selected Isaac out of high school with the 29th overall pick in last year's draft because of his bat. The 6-foot-3 lefty-hitting first baseman has 70-grade raw power, and the early returns on his hit tool are very encouraging. In May, he had a 10.2 percent strikeout rate and 20.4 percent walk rate, and his 1.25 BB/K is the fifth-best mark in the Carolina League. He missed two weeks in the middle of the month with an undisclosed injury and never landed on the injured list.
