Two stars were born Sunday at Citi Field.

The first was Steven Matz, the New York Mets' 24-year-old rookie who struck out six in 7 and two-thirds innings while also going 3-for-3 at the plate with 4 RBIs. It was a storybook debut for a man who grew up just 50 miles away in Stony Brook, Long Island.

There was no Mets fan more excited during Matz's debut than his 82-year-old grandfather, Bert Moller. Cameras caught Moller celebrating during one of Matz's hits, and his reaction is priceless.

As one can imagine, Moller got lots of love on Twitter:

Afterwards, Moller gave a classic interview in which he tried to sum up his feelings.

"You just can't put it into words," Moller said. "There are no words. There's tears, there's smiles, there's happiness.

Moller also said his phone was about to blow up due to all the e-mails he was getting.

Not surprisingly, Moller isn't familiar with the concept of "going viral."

“They said I went I viral, and I said, ‘What the heck is that?’” Moller told the New York Post. “It was crazy. When he hit that double, it was like: ‘Oh my gosh.’ You couldn’t control your emotions. I was so happy.
