Burgos, 25-years-old, was signed as an international free agent on April 15, 2019, out of the Dominican Republic. Burgos spent parts of three years in rookie ball in the Dominican Summer League and Arizona Complex League from 2019-22. He was promoted to the Single-A Modesto Nuts in '22.

This year, in 21 outings with the Double-A Arkansas Travelers, Burgos posted a 0.64 ERA with 29 strikeouts in 28 innings pitched. He allowed an opposing batting average of .106 with a 0.61 WHIP. Burgos was promoted to the Triple-A Tacoma Rainiers on June 24. In his only outing at the Triple-A level, he threw a scoreless seventh inning against the Round Rock Express on Tuesday, he didn't allow a hit or walk a batter and struck out one.

Across his stint in Double-A and his one outing in Triple-A, Burgos has a 0.62 ERA this season with 30 strikeouts in 29 innings pitched in 22 appearances.
