Mayza signed one-year, $1.15 million contract with the Pirates on Monday, Alex Stumpf of MLB.com reports.
Mayza, who struggled through one of the worst seasons of his big-league career a season ago across stops with the Blue Jays and Yankees, will have the luxury of a fresh start following Monday's agreement. He was brilliant for the Blue Jays during the 2023 campaign, posting a sparkling 1.52 ERA and 1.22 WHIP with 53 strikeouts and one save across 53.1 innings, so he'll have his sights set on returning to form in Pittsburgh.
