David Robertson News: Announces retirement from baseball

Robertson announced his retirement from professional baseball on his X account Friday.

He will retire after collecting 179 career saves, a 2.93 ERA and 31.9 percent strikeout rate. Robertson made one All-Star team and won a World Series in 2009 as a setup man with the Yankees.
