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
