There was a new rule implemented in the Fogelberg household this summer.
It's one brothers Keenan and Brett know well.
"The rule is if the trash talking gets out of hand, we could both be taken off the teams and we won't play the rest of the year," Brett said. "During the summer we went back and forth all the time. It got pretty bad."
The Fogelberg brothers add a unique splash to the Merced-Golden Valley water polo rivalry.
The two teams took to the pool at Merced College on Tuesday night.
It wasn't just Golden Valley against Merced.
It was brother versus brother.
Fogelberg versus Fogelberg.
Brett scored two goals and assisted another as Merced crushed Golden Valley 16-2, earning the younger Fogelberg brother bragging rights for at least a couple weeks.
"It really is a fun sibling rivalry," said Keenan, a senior at Golden Valley. "Not many brothers get to play on rival teams in the same sport.
"When we get in the water there's a lot of smack talking. It's fun playing each other. There's little insults here or there."
The Fogelbergs live in the Golden Valley enrollment area. Keenan chose Golden Valley because he also wanted to play saxophone in the Cardinal Regime.
Brett grew up wanting to wear black and orange. Father Val used to coach football at Merced during the Mark Speckman era and still teaches at the campus.
Having two kids squaring off against each other has made watching games interesting.
"You don't want to root for one kid over the other," Val said. "It's kind of difficult, nerve wracking. You want both to do well and for their teams to do well. It's a lot harder than I thought it would be."
"They were matched up against each other during a tournament in Turlock. They went after each other pretty good. Keenan isn't going to let his younger brother pull any fast ones."
The brothers found themselves matched up against each other 30 seconds into Tuesday's game with Keenan drawing the defensive assignment against Brett.
"During the game, if one of us makes a good play, we might look at the other and smile or raise an eyebrow," Brett said. "There's no anger or hatred when we play each other, but we might try to grab the other's wrist and dunk him."
Brett showed why he's playing at the varsity level as a sophomore midway through the second quarter when he used a spin move on a breakaway to get by a GV defender, and then he used a soft touch to score a goal to give Merced (4-1 Central California Conference) a 4-0 lead.
Brett later added another goal on a pass from teammate Kaleb Jones to extend the lead to 7-0.
"We're two years a part, so Keenan and I are always competing in height, weight and strength," Brett said. "We wrestle around the house all the time and the winner always slaps the ground for the pin.
"When we play football with our friends, they always like to put us on opposite teams to see us go at it. He's my older brother so he can still beat me up a little bit."
