CLEVELAND — For winning the 2019 Home Run Derby Monday night at Progressive Field, the Mets’ Pete Alonso gained a $1 million prize, a cool, ginormous medallion from Daddy Yankee and enough social-media mentions to feed a Kardashian for a week.

For serving up the 57 gopher balls that Alonso hit into the stratosphere, Derek Morgan got a supporting role in a fantasy. And that, he insisted, easily sufficed.

“Honestly, just to be here, that’s all that matters to me,” Morgan, Alonso’s second cousin, said in a news conference as he sat next to the champion. “Everybody is talking about him dreaming, and I’m still dreaming. I’m catching myself sitting here just flashing back to just the memories I had 20 minutes ago. It’s just surreal. And all that matters is that he asked me. I’m just blessed and honored that he asked me.”

Morgan, who played second base at both St. Bonaventure and Indiana Tech, lives in nearby Copley, about a half-hour drive from Cleveland, making this extra special. The two men appeared to grow increasingly in sync as the night advanced. In the first round, needing to top the 13 hit by ballpark-favorite Carlos Santana of the Indians, Alonso slammed only six in the first 2 minutes and 16 seconds. He went deep eight times in the final 1:44, skipping the 30-second bonus he had earned, and that propelled him to a 20-19 victory over the Braves Ronald Acuna Jr. and then a 23-22 triumph over fellow rookie Vladimir Guerrero Jr. of the Blue Jays for the crown.

“The first round, we got the jitters out,” Morgan said. “I think we figured it out after the first timeout in that first round. But [we] just stayed positive and [kept] grinding and surviving.”

“After we finally got in that rhythm, it was money,” Alonso said. “It was money.”

Quite a lot of money, in fact. Some of which surely will go to Morgan to complement his amazing memories.
