Texas Rangers right-handed pitching prospect Kumar Rocker is making his second career major-league start on Thursday at Globe Life Field against the visiting Toronto Blue Jays. Rocker, the team's No. 2 prospect per MLB Pipeline, went four innings in his major-league debut on Sept. 12 against the division-rival Seattle Mariners and allowed just one earned run on three hits (one homer) while walking two and striking out seven to earn another start. With the Rangers out of playoff contention despite winning the World Series last fall, they have elected to give Rocker a little run in the big leagues to close out the year after he was dominant down on the farm in 2024 after coming back from Tommy John surgery. Rocker may not go deep in Thursday's contest, but he still has plenty of strikeout upside. There's a good chance he'll make one more start before the season is over.
