Kelby Tomlinson made his MLB debut Monday evening with the defending World Series Champion Giants. After four-and-a-half minor league seasons, the 25-year-old infielder finally got the call-up from the AAA Sacramento River Cats.

Tomlinson's debuted late into Monday night, with the Giants and Braves locked in a 7-7 tie in the 12th inning. As he stepped to the plate, his wife, Tiffany, who flew from San Jose to Atlanta to attend the game with her father, Bob Prater, showed some nerves.

But when Tomlinson got a hit, Tiffany and his father-in-law went bonkers.

Tiffany may have said an expletive, and she covers her mouth quickly in the video. But who came blame her: Tiffany and Prater's ecstasy is a feel good sight.

Game announcers identified pitcher Hunter Strickland's wife, Shelley, as the woman who comes over to celebrate with Tiffany in the video. Strickland spent parts of the last two years playing with Tomlinson on the River Cats.

"I tried to keep it together the best I could," Tiffany told the San Jose Mercury News. "I couldn't believe it. I don't think I believed it until he got on deck and got ready to hit. Then it was, 'My goodness, it's actually going to happen.'

"I'm still in disbelief. It was all the emotions all at once. It was so exciting. I wanted to throw up. I'm just so proud of him."

That wasn't even the end of the story. Tomlinson came all the way around to score his first MLB run on an RBI off the bat of Buster Posey. However, the Braves stormed back for two runs in the bottom of the 12th, winning 9-8 on a walk-off home run by Adonis García.
