As a student at Pingjen Senior High School in Taoyuan, Yang was selected to play on the Taiwanese national team in the 2022 and 2023 U-18 Baseball World Cups. In the 2022 tournament, he pitched against the United States, recording a complete game win. In that game, he gave up two earned runs to Bryce Eldridge, who would later become a top prospect in the Giants organization.
In 2024, Yang was again selected to play on the national team. He was the starting pitcher in the final game of the U-18 Asian Baseball Championship against Team Japan. He gave up 5 hits over 2.2 innings, recording 3 strikeouts and 1 earned run. The team went on to win the game.

The Giants' Pacific Rim Area scout presented Yang with a Giants jersey at a press event in January 2025, where Yang revealed that fellow Taiwanese player Wei-En Lin had encouraged Yang to join him at the Oakland Athletics. At the time of his signing, Yang joined two other Taiwanese prospects in the Giants system, Kai-Wei Teng and Chen-Hsun Lee. He was the first player from the University of Taipei to sign with an MLB team since C. C. Lee in 2008.
