Carter Baumler Secures Rangers Bullpen Spot After 96.8 MPH Strikeout

Rookie right-hander Carter Baumler made the Texas Rangers Opening Day roster after striking out Isaac Collins during a Monday night mound visit from Skip Schumaker.

ARLINGTON, Texas -- Texas Rangers manager Skip Schumaker utilized a fifth-inning mound visit on Monday night to inform rookie right-hander Carter Baumler he had officially made the Opening Day roster. The announcement occurred at Globe Life Field after Baumler retired the first two Kansas City Royals batters he faced in the frame. Standing alongside catcher Danny Jansen and all four Rangers infielders, the 24-year-old reliever learned he would begin the season in the Texas bullpen rather than being removed from his final spring training appearance. Carter Baumler punctuated the career milestone by throwing a 96.8 mph fastball to strike out Isaac Collins swinging, effectively ending the inning and his spring campaign.

Throughout eight spring training games, the rookie pitcher logged 9 1/3 innings, allowing only one earned run while recording 10 strikeouts. This statistical performance secured his position on the major league staff despite the fact that he has never pitched above the Double-A level in his professional career. During the mid-game interaction, Jansen patted his catcher's mitt against Baumler's chest as the infielders offered congratulations before the right-hander composed himself to face Collins. Upon returning to the dugout following the third out, Baumler hugged Schumaker and received high fives from his teammates to celebrate his first big league call-up.

From Rule 5 Draft to the Texas Bullpen

The path for Carter Baumler to the Rangers roster involved multiple organizational shifts within a single calendar year. Originally a fifth-round selection by the Baltimore Orioles in the 2020 amateur draft out of an Iowa high school, Baumler underwent Tommy John surgery shortly after entering professional baseball. He remained in the Orioles system from 2022 through 2025 but was excluded from their 40-man roster last fall. The Pittsburgh Pirates subsequently selected him in the first round of the Rule 5 draft during the December winter meetings, only to trade him to Texas that same day.

Baumler admitted during an in-game TV interview on the Rangers Sports Network that he initially expected to be pulled from the contest when he saw Schumaker approaching the mound. The manager noted that he wanted to create a memorable moment, recalling his own call-up in Memphis, Tennessee, as a primary motivation for the unconventional announcement. Schumaker emphasized that the exact game and moment of a player's first promotion remains a permanent memory, leading him to coordinate the surprise in front of the active infield defense.

Statistical Breakdown of Baumler’s Spring Performance

Baumler’s efficiency in the 9 1/3 innings pitched this spring was a deciding factor for the coaching staff. By maintaining a high strikeout-to-inning ratio and limiting damage to a single earned run, he demonstrated readiness for high-leverage relief roles. His velocity peaked at 96.8 mph during the Monday night sequence, a speed that ultimately froze Isaac Collins to secure the final out of the fifth. This performance validated the Rangers' decision to acquire him via trade immediately following his Rule 5 selection by Pittsburgh.

Reflecting on his journey, the right-hander noted that a few years ago he would not have anticipated this trajectory, especially given his recovery from major elbow surgery early in his career. He attributed his current success to maintaining a consistent work ethic and "hammering away" while navigating the minor league levels. The transition from being left off Baltimore's 40-man roster to securing a spot in the defending champions' bullpen represents a significant shift in his professional standing over a four-month period.

Tactical Implications for the Rangers Relief Corps

By adding Baumler to the Opening Day roster, the Rangers are integrating a power arm with significant strikeout potential into their late-inning options. The decision to keep him on the active roster is also influenced by his Rule 5 status, which typically requires a player to remain on the major league roster for the duration of the season or be offered back to his original club. Schumaker’s choice to announce the news on the mound served as a public endorsement of the rookie's stuff and his ability to handle pressure situations, such as finishing an inning immediately after receiving life-changing news.

The Rangers bullpen will now feature the 24-year-old as a primary relief option as they begin their title defense. His ability to jump from Double-A directly to the majors suggests the organization views his 96.8 mph heater and secondary offerings as ready for top-flight competition. As the team breaks camp, Baumler moves from a prospect fighting for a look to a designated member of the Texas pitching staff, fulfilling a goal he has pursued since his high school days in Iowa and his subsequent recovery from reconstructive surgery.
