Mayza allowed one hit in 1.1 innings to earn the save in Sunday's 2-1 win over Detroit.
Toronto's regular closer, Jordan Romano, covered two innings to earn the win Saturday, opening the door for Mayza to notch his first major-league save. The 29-year-old southpaw was never in any real danger of giving up the one-run lead. He's pitched to a solid 3.64 ERA, 1.00 WHIP and 43:9 K:BB across 42 innings this year. He's added a 4-2 record, 13 holds and two blown saves, typically operating in high-leverage situations.
