Selected 10th overall by the Mets in the 2021 MLB Draft, Rocker had a history of medical concerns that led to New York passing on signing him.
Undeterred, Rocker took an unusual route, signing with the independent Tri-City ValleyCats and maintaining his draft eligibility. His comeback story gained new life when the Rangers stunned the baseball world by picking him third overall in 2022.
However, his debut was delayed yet again when he needed Tommy John surgery, shelving him until July of this season.
But since returning to action, Rocker has dominated. In seven starts split between Double-A and Triple-A, he has a microscopic 0.91 ERA and held hitters to a .128 average. Rocker has a blazing fastball (98.7 mph average) and his command is sharper than ever (47 strikeouts to just three walks).
Rocker’s debut is pivotal for the reigning World Series champion Rangers, who are 70-74 heading into Tuesday’s game against the Arizona Diamondbacks. FanGraphs gives Texas just a 0.7 percent chance to make the playoffs, but Rocker’s presence gives the Rangers hope that this season could be a one-year blip.
With veteran pitchers Max Scherzer, Andrew Heaney and potentially Nathan Eovaldi set to enter free agency, the Rangers will need a fresh arm to boost their rotation. Rocker fits the bill.
Thursday’s start in Seattle will mark just Rocker’s 17th appearance since being drafted. The immediate spotlight will be on his performance, but Rangers fans should focus on the big picture.
As Rangers GM Chris Young told Evan Grant of The Dallas Morning News, “He’s earned the opportunity… the ability to get major league experience will serve him well for next season.”
Adding to the excitement is Rocker’s reunion with Leiter, another top Rangers right-handed pitching prospect. The Vandy Boys, once collegiate superstars, have the chance to be a fabulous duo in the majors.
It’s not just a nice storyline — it’s a glimpse of the future for the Rangers, who are positioning themselves for a serious run in 2025.
As Texas looks to rebound next season, Rocker’s emergence could be the spark that ignites a turnaround. With electric stuff, sharp command and the hunger to prove himself, he is a name to watch for Thursday and beyond.
