Professional career

Tampa Bay Rays

O'Brien signed with the Rays and made his professional debut that year with the Princeton Rays of the Advanced Rookie Appalachian League, going 1–0 with a 2.20 ERA over 11 games (ten starts).[8] During the season, he was named Appalachian League Pitcher of the Week twice.[9] In 2018, he began the season with the Bowling Green Hot Rods of the Single–A Midwest League (with whom he was named an All-Star) before being promoted to the Charlotte Stone Crabs of the High–A Florida State League, with whom he ended the year; over 25 games (13 starts) between both teams, he went 8–4 with a 2.75 ERA.[10][11][12] In 2019, he began the season with Charlotte and was promoted to the Montgomery Biscuits of the Double–A Southern League in May. Over 20 games (17 starts) with the two clubs, he pitched to a 7–6 record and 3.16 ERA.[13]

O'Brien did not play in a game in 2020 due to the cancellation of the minor league season because of the COVID-19 pandemic.[14]

Cincinnati Reds

edit

On August 28, 2020, the Rays traded O'Brien to the Cincinnati Reds in exchange for Cody Reed.[15][16] On November 20, 2020, the Reds added O'Brien to their 40-man roster to protect him from the Rule 5 draft.[17] To begin the 2021 season, he was assigned to the Louisville Bats of the Triple-A East.[18] Over 23 games (22 starts), O'Brien pitched to a 7–7 record, a 4.55 ERA, and 121 strikeouts over 112+23 innings.[19]

On September 28, 2021, the Reds recalled O'Brien to the active roster to make his MLB debut versus the Chicago White Sox.[20][21] He was the starting pitcher and threw 1+13 innings, giving up two solo home runs while walking three and striking out two.[22]

On April 13, 2022, the Reds designated O'Brien for assignment to make room for Nick Lodolo.[23]

Seattle Mariners

edit

On April 16, 2022, the Reds traded O’Brien to the Seattle Mariners for cash considerations or a player to be named later.[24] (On June 3, minor league infielder Luis Chevalier was sent to Cincinnati to complete the trade).[25] He was designated for assignment on May 27. He cleared waivers and was sent outright to the Triple-A Tacoma Rainiers on June 2.[26]

O'Brien spent the entirety of the 2023 season in Triple–A with Tacoma. In 51 appearances, he registered a 2.29 ERA with 86 strikeouts and 15 saves across 55.0 innings of work.[27]

St. Louis Cardinals

edit

On November 5, 2023, O'Brien was traded to the St. Louis Cardinals and subsequently added to the 40–man roster.[28] On March 26, 2024, the Cardinals officially revealed that O'Brien had made the Opening Day roster. On March 31, he was placed on the injured list with a flexor strain,[29] and was transferred to the 60-day injured list on May 6.[30] O'Brien was activated on August 11.[31]
