Rest-of-Season Projections
2024 Fantasy Outlook
Hernandez had a shaky 2023 season, which he split almost exactly evenly between the majors and Triple-A Round Rock. His 4.3 BB/9 and 1.1 HR/9 served as a bad combination, which led to a 5.40 ERA and 1.58 WHIP while in the big leagues. Hernandez was also sidelined in the playoffs due to a shoulder injury, so his health remains in question entering the spring. Read Past Outlooks

Past Fantasy Outlooks
2023
2021
Hernandez returned in July after a lengthy recovery from April 2021 Tommy John surgery. The right-hander posted a near-20 percent walk rate in 16 minor-league rehab outings, but Texas felt he was ready to go and immediately featured him in high-leverage. The 26-year-old recorded his first of four saves in just his fifth appearance of the season, but only spent about two weeks closing before Texas turned to Jose Leclerc. Hernandez reached triple-digits with his fastball, but could only muster a 20.6% strikeout rate and walks were still an issue (17 in 30.1 innings) upon returning to the big leagues. He makes up for his lack of strikeouts with plenty of groundballs (52.8% for his career), but the number of baserunners he allows (career 1.31 WHIP) isn't suited for closing.
