SURPRISE, Ariz. (AP) — Top prospect Sebastian Walcott of the Texas Rangers is having elbow surgery, and the infielder is expected to miss most of the season.

The Mariners’ big question now is bullpen, which isn’t the worst thing

Rangers president of baseball operations Chris Young said Thursday that Walcott has a UCL injury and was experiencing elbow discomfort. He could be back by the end of the season but it’s too early to tell.

The 19-year-old Walcott is the No. 7 prospect in baseball, according to MLB Pipeline. He hit .255 with 13 home runs, 59 RBIs and 32 stolen bases at Double-A Frisco last year.

Walcott received a non-roster invite to spring training.

Rangers reunite with starter

Jordan Montgomery has agreed on a one-year deal to rejoin the Rangers, three seasons after being part of their only World Series championship and while the left-hander continues rehabbing from a second elbow reconstruction surgery.

A person with knowledge of the deal confirmed the move on Wednesday. The person spoke to The Associated Press on condition of anonymity because the deal hadn’t been finalized or announced.

The Dallas Morning News first reported the deal and said it was worth $1.25 million plus potential performance bonuses.

A trade-deadline acquisition from St. Louis in 2023, Montgomery went 4-2 with a 2.79 ERA in 11 regular-season games for the Rangers before winning two AL Championship Series games. That included 2 1/3 innings in relief in the Game 7 ALCS clincher in Houston. He went 3-1 in six games that postseason, the loss coming when starting Game 2 of the World Series against Arizona.

He then left in free agency and didn’t sign until late the following spring with the Diamondbacks, going 8-7 with a 6.23 ERA in 2024 before missing all of last season.

Depending on his rehab, Montgomery could provide some pitching depth for the Rangers in the second half of this season. His surgery last year was done by Dr. Keith Meister, one of their team physicians.

Because the Rangers went into spring training with a full 40-man roster, they will have to make a move to clear a spot on the active roster for Montgomery before they can place him on the injured list.

Over eight big league seasons with the New York Yankees, St. Louis, Texas and Arizona, the 33-year-old lefty is 46-41 with a 4.03 ERA in 166 games (161 starts).
