The Angels' 11th round pick in the 2021 draft out of Arizona, Chase Silseth quickly emerged as a top pitching prospect. In September 2021, he became the first of the Angels' 2021 draft picks to reach Double-A when he made two starts for Rocket City in a September series at Birmingham, taking the loss in each start.
He began his first full professional season with the Trash Pandas in 2022 and was stellar, allowing two or fewer runs with at least six strikeouts in his first five starts of the season, including three straight quality starts from April 22 through May 5. On April 24, he was named Southern League Pitcher of the Week following a win at Tennessee where he allowed one run over six innings with seven strikeouts.
On May 13, he became the first player from the entire 2021 draft class to reach the big leagues with his promotion to the Angels after just eight professional outings. In his debut that night against Oakland, he earned the win with six scoreless innings, striking out four for his first MLB win.
Silseth was later recalled by the Angels from Rocket City on multiple occasions, but always found himself on the mound when the Trash Pandas needed a big win. During the 2022 season, Silseth started both the first and second half title clinching games, as well as the first playoff game in Toyota Field history.
He ended the regular season with four straight wins, including the first no-hitter in Trash Pandas history on September 3 vs. Biloxi, when he took a perfect game into the seventh inning, striking out 10 before Luke Murphy and Eric Torres completed the 8-0 blanking.
