Career
Kochanowicz attended Harriton High School in Rosemont, Pennsylvania. He played for the travel club Houston Banditos after his freshman season.[1] He was drafted by the Los Angeles Angels in the third round, with the 92nd overall selection, of the 2019 MLB draft.[2][3] Kochanowicz did not play in a game in 2020 due to the cancellation of the minor league season because of the COVID-19 pandemic.[4] He made his professional debut in 2021 with the Single-A Inland Empire 66ers, logging a 4–2 record and 6.91 ERA with 73 strikeouts across 20 games (18 starts).[5]
Kochanowicz returned to Inland Empire in 2022, compiling a 4–4 record and 4.99 ERA with 53 strikeouts over 17 appearances (9 starts).[6] He was the California League pitcher of the week in mid-July.[7] He split the 2023 campaign between the High-A Tri-City Dust Devils and Double-A Rocket City Trash Pandas. In 21 starts between the two affiliates, Kochanowicz accumulated a 5–5 record and 5.27 ERA with 69 strikeouts across 94 innings pitched.[8] On November 13, the Angels added Kochanowicz to their 40-man roster to protect him from the Rule 5 draft.[9][10]
Kochanowicz was optioned to the Triple-A Salt Lake Bees to begin the 2024 season.[11] On July 11, he was promoted to the major leagues for the first time.[12] He threw three innings, yielded five runs on seven hits, hit two batters with pitches, and took a loss against the Seattle Mariners.[13] Kochanowicz earned his first MLB victory against the Washington Nationals on August 11.[14][15]
In 2025, Kochanowicz went 3–11 with a 6.81 ERA. His ERA was the highest of any pitcher with at least 110 innings pitched, and his strikeout-to-walk rate and home runs allowed per nine innings were among the worst in the majors.[16]
Kochanowicz made 13 starts for Los Angeles in 2026, compiling a 2-5 record and 6.19 ERA with 47 strikeouts over 64 innings of work. On June 9, 2026, it was announced that Kochanowicz would require Tommy John surgery, ending his season.[17]
