Carlos Rodon’s postseason career with the Yankees seemed to be off to a great start – until the southpaw fell apart in the fourth inning of Game 2 of the ALDS against the Royals in The Bronx.

In a scene all too familiar to Yankee fans, Rodon saw his stuff disappear quickly, this time in a critical situation, as he allowed four runs in the top of the fourth inning after the Yankees took a 1-0 lead in the bottom of the third. .

Rodon looked dominant in the first two innings, striking out four and retiring six of the first seven batters he faced before throwing about two singles in the third.

But Salvador Perez opened the fourth inning with a booming home run to left on a hanging 2-0 slider, tying the game at 1-1, and things only got worse from there.

Yuli Gurriel followed with a single and advanced to second base on a wild pitch.

Ian Hamilton came in and gave up an RBI single to Garcia for the fourth and final run of the inning.
