Diaz tossed one scoreless inning Friday as he picked up the save against Atlanta. He allowed no hits and one walk while striking out two.
Coming out of camp, it was unclear who would be the team's top option in the ninth inning, but the Mets called on Diaz to preserve the one-run lead in Friday's contest. He allowed a walk with one out, but he struck out the final two batters of the game. While the right-hander should have less job security in 2020 after recording a career-worst 5.59 ERA and 1.38 WHIP with seven blown saves last season, his usage Friday is encouraging.
