2026 Fantasy Outlook
Isaac played his final game of the 2025 season in late June due to a mysterious injury. This offseason, Isaac revealed that he had brain surgery in July and is expected to be 100 percent recovered for spring training. Isaac slashed .201/.366/.446 with nine home runs, a 19.4 percent walk rate and a 29.7 percent strikeout rate in 41 games at Double-A prior to being shut down. His .245 ISO was right up there with some of his top marks in the lower levels, but a career-low .244 BABIP and traditionally high strikeout rate contributed to his poor batting average. We can't know what to expect from Isaac as he recovers from this live-saving procedure, but if it were just a normal injury, he'd seem like a decent buy-low target in dynasty leagues. Even in his down run at Double-A, the 21-year-old first baseman was 44 percent better than league average. The lefty-hitting Isaac moves well for a towering 6-foot-4 slugger - he stole 15 bases in 2024 - but he also seems likely to get platooned early in his career (.369 OPS vs LHP in 2025, .662 OPS vs LHP in 2024). Isaac is highly unlikely to reach the majors until at least 2027. Read Past Outlooks
Underwent brain surgery in July
Isaac revealed Friday that he underwent brain surgery in July, Marc Topkin of the Tampa Bay Times reports.
Analysis
Isaac's last game at Double-A Montgomery came on June 25, but he had asked the Rays not to divulge details of his medical status during the season. However, Isaac revealed the cause of his absence in an Instagram post Friday, noting that the brain surgery was "life-saving." Isaac recently attended a hitting camp and is expected to be 100 percent for the start of spring training. The first baseman slashed .201/.366/.446 with nine home runs in 41 contests for Montgomery in 2025 and will likely need another full year of seasoning in the minors in 2026.

Past Fantasy Outlooks
2025
2024
2023
Isaac looks the part of a franchise first baseman in the making, and his track record of performance is very strong, but a late-season spike in strikeouts has increased his perceived volatility in dynasty leagues. Isaac slashed .310/.395/.579 with 12 home runs, 13 steals and a 27.6 percent strikeout rate in his first 54 games for High-A Bowling Green before missing two weeks with an undisclosed injury. After returning in late June, Isaac slashed .213/.339/.372 with seven home runs, three steals and a 41 percent strikeout rate over the final 53 games of his season, which included 31 games at Double-A after an early-August promotion. He made up for the lost time with a .957 OPS, three homers and a 40.3 percent strikeout rate in 15 Arizona Fall League games. He's a big guy (6-foot-3, 240 pounds), but Isaac happens to be 27-for-30 on stolen-base attempts in 209 games, so he could flirt with double-digit steals early in his big-league career. If Isaac's 2024 strikeout issues quickly start to look like an outlier, he'll surge back up prospect rankings, but if he looks like the same whiff-happy hitter early in 2025, he'll fall outside the top 50. We advise buying low, as Isaac still has a very high ceiling with youth and strong makeup on his side. He turns 21 this offseason and will return to Double-A to start the year.
