Royals infielder Ryan McMahon provided the highlight for Kansas City, belting a go-ahead home run in the eighth to briefly put the Royals in front.
The Yankees answered with a late rally to reclaim the lead and pull away for the 4-2 win.
Meanwhile, Chad Green, a seven-year veteran of the Yankees, remains unsigned as an MLB free agent as of April 18.
Green is coming off a 3-2 campaign with a 5.56 ERA in 45 appearances for the Toronto Blue Jays last season.
Drafted in the 11th round of the 2013 MLB Draft, Green spent his first seven seasons with the Yankees, including a standout 2017 stretch (5-0, 1.83 ERA in 40 games) before moving on.
As teams evaluate bullpen options, Green’s status as a former Yankee and veteran reliever keeps him on the radar for potential landing spots.
