Marcano, Jack Suwinski and Michell Miliano were traded from the Padres to the Pirates in exchange for Adam Frazier on Sunday, Ken Rosenthal of The Athletic reports.
Marcano made his major-league debut earlier this season, and he hit .182 with a double, seven runs and three RBI in 25 games with the Padres. He's spent most of the year at the Triple-A level and could report to Triple-A Indianapolis, but he could fill Frazier's spot at second base at some point in 2021.
