David Robertson, not Mariano Rivera, was called upon to protect a one-run lead in Friday's victory against the Astros. As he often does, Robertson came through the inning unscathed, striking out one in the process. It was a passing of the torch moment for the Yankees, as Robertson is slated to take over as the Yankees primary closer next season with the departure of Mariano Rivera. He now owns a 5-1 record, 2.07 ERA, 1.06 WHIP and 77/18 K/BB ratio over 65 1/3 innings while converting three of his five save chances.
