He was signed midseason this year by the Rays after the Dodgers cut him.

Now, he has nine home runs and the second-best slugging percentage of his disappointing career thus far.Even if this level of play doesn’t keep up, d’Arnaud’s night in New York will be a favorite obscure reference among baseball fans for the remainder of his career. Despite his low profile and minimal expectations at this point in his career, d’Arnaud delivered a surprise power onslaught at Yankee Stadium on Monday, hitting three home runs and producing all five RBIs in a 5-4 Rays victory.After the game, he told reporters it was the “coolest night ever” in his career. Hitting a go-ahead home run against Yankees closer Aroldis Chapman — with two outs and two strikes no less — makes that statement believable.
