Hancock was selected sixth overall by the Seattle Mariners in the 2020 Major League Baseball draft. He signed with the Mariners on June 25, 2020, receiving a $5.7 million signing bonus. He reported to the team's alternate training site before the shortened 2020 season but experienced shoulder fatigue after his first throwing session and was shut down for the season.
Hancock made his professional debut in 2021 with the High-A West Everett AquaSox. Hancock was selected for the 2021 All-Star Futures Game, but a shoulder injury kept him out of the game. He was promoted to the Double-A Arkansas Travelers in August. In 12 starts with the two teams, he went 3âÂÂ1 with a 2.62 ERA and 43 strikeouts over innings. His season ended in early September due to another shoulder injury. Hancock returned to Arkansas to start 2023, making 20 starts and posting an 11âÂÂ5 record and 4.32 ERA with 107 strikeouts across 98 innings pitched.
On August 9, 2023, the Mariners selected Hancock's contract and promoted him to the major leagues. He made his MLB debut that night starting against the San Diego Padres. He pitched 5 innings, giving up 2 hits, 1 earned run, and 3 walks with 3 strikeouts. On August 20, Hancock was removed from a start against the Houston Astros with a right shoulder strain. He was placed on the injured list on August 21, and one day later, he was transferred to the 60-day injured list, again ending his season early. In 3 starts for Seattle in 2023, he had a 4.50 ERA with 6 strikeouts in 12 innings of work.
Hancock was the Mariners sixth starter in 2024, splitting time between the Mariners, the Triple-A Tacoma Rainiers, and the injured list. He was in the starting rotation on Opening Day and made seven starts with a 5.24 ERA before being optioned to Tacoma on May 8, just before Bryan Woo made his season debut. Hancock returned to Seattle on June 13 for a spot start, allowing 2 runs in 7 innings before being abruptly sent back to the minors. He returned to Seattle for another spot start on July 6, taking the loss after 4 innings of work, and was again ticketed back to Tacoma. He returned to the Mariners on September 13, filling in for the injured Luis Castillo. In three starts to close out the year, Hancock had a 4.70 ERA in innings. He finished the season with a 4âÂÂ4 record with a 4.75 ERA and 39 strikeouts in innings.
Hancock split 2025 between Seattle and Tacoma. He failed to finish the first inning in his first start. He was demoted in early July after going 3âÂÂ5 with a 5.47 ERA in 15 starts. He returned to the majors at the end of August as a reliever. He went 1âÂÂ0 with a 1.42 ERA in 7 relief appearances. In his first MLB postseason, he allowed two runs and five walks in four innings pitched in the American League Championship Series.
