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
RANKS
Rest of Season
From Preseason
$Signed a one-year, $1.2 million contract with the Rangers in January of 2024.
Activated from injured list
PTexas Rangers
April 23, 2024
The Rangers activated Hernandez (lat) from the 15-day injured list Monday.
ANALYSIS
Hernandez got a late start to the season due to a right lat strain but is ready to roll now after allowing just three runs with a 14:4 K:BB over 10 rehab innings with Triple-A Round Rock. The righty could eventually work his way into high-leverage situations but will probably be used earlier in games initially.

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.
Hernandez was electric coming out of the Rangers' bullpen in 2020, posting a solid 2.90 ERA and 1.03 WHIP with 31 punchouts over 31 innings. He also finished with a 5-1 record along with five holds. Hernandez's nasty sinker makes it extremely difficult for hitters to lift the ball out of the ballpark, and this was evident by just two home runs surrendered last season. The 24-year-old's command is also something to note, finishing the year with a 3.9 K/BB. The youngster easily fits into the class of upcoming elite relievers, and he should be in a position to receive plenty of high-leverage opportunities in 2021, even with Jose Leclerc returning from a shoulder injury and factoring into the mix near the back end of the bullpen.
