Corey and Kyle Seager met during regular-season play for the first time in their careers Monday, and the pair of stars traded home runs - as well as knowing nods while rounding the bases - with the Los Angeles Dodgers playing host to the Seattle Mariners.

Corey opened the proceedings by hitting a three-run bomb in the bottom of the second inning. Kyle did not look amused:

Kyle got even quickly, though, notching a solo shot of his own the very next frame and earning a slightly warmer expression from his brother:

The Seagers are the first set of brothers to homer in the same game as opponents since 2001, when Felipe Crespo of the San Francisco Giants and Cesar Crespo of the San Diego Padres each went deep on June 7, according to Bill Plunkett of The Orange County Register.

It was Corey's team that earned the actual victory, though, as the Dodgers powered past the Mariners in a high-scoring affair 11-9. The Seager Bowl continues Tuesday, with the four-game series concluding on Thursday.
