Boone, a lefty, was named to the second team. He was one of several pitchers from the West Coast to receive preseason honors.
Players on the Perfect Game/Rawlings Preseason All-American teams were selected based on a combination of factors, including statistics from both 2019 and 2020, prospect status, 2021 expectations, and ranking relative to their draft status, said the website.
Boone, a 6-2, 175-pound sophomore, was the 2019 Big West Freshman of the Year, and earned Freshman All-American honors from Collegiate Baseball, Perfect Game and Baseball America.
He posted an 8-0 record with a 2.78 ERA over 81.0 innings, and ranked third on the team with 80 strikeouts.
In the pandemic-shortened 2020 season, Boone went 2-1 with a 2.53 ERA, recording 31 strikeouts in 21.1 innings.
The Gauchos are the only Big West team ranked amont PerfectGame.org's top-25. They were unranked to open the 2020 season but finished at No. 18.
Zach Torra, Boone's teammate and fellow left handed starting pitcher was named second team All-American by Collegiate Baseball while UCSB was ranked No. 8 in its preseason poll, the highest preseason ranking in school history.
