Video: Shaquem Griffin throws ceremonial first pitch to Shaquill Griffin at Mariners game

The Seattle Mariners have been Major League Baseball’s “Cardiac Kids” for the 2018 season. While they have a run differential of just +19, they’re a perfect 7-0 in extra innings and possess the fourth-best record in the entire league, sitting at 52-31. It’s been 17 years since the M’s last made the playoffs — literally so long ago that CenturyLink Field hadn’t opened yet — and now Mariners fever is back in the Emerald City.

In Seattle’s 4-1 home win against the lowly Kansas City Royals on Friday, the ceremonial first pitch was thrown by Seattle Seahawks rookie linebacker Shaquem Griffin. The twist? The catcher was none other than his twin brother, second-year cornerback Shaquill.

Additional footage shows the lead-up to the pitch, including their promotional spot for the Mariners, an interview with Jen Mueller, and meet-ups with catcher Mike Zunino and 2nd Baseman Dee Gordon.

Last month, rookie running back Rashaad Penny threw the first pitch in the Mariners’ win against the Tampa Bay Rays. Russell Wilson, an actual baseball player with a Minor League contract with the New York Yankees, tossed this ball into the dirt two weeks ago, but the Mariners did beat the Boston Red Sox that day, so clearly the key to Mariners home wins is you need more Seahawks throwing out the ceremonial first pitch.
