More often than not when an athlete wins a championship or accepts an award, the first person he thanks is dear old mom.

This second Sunday of May, sports stars from every major league around the country took to Twitter to honor their mothers, like Washington Redskins quarterback Robert Griffin III and Tampa Bay Rays ace David Price.

While most won't be writing copy for Hallmark anytime soon, each athlete credited their mother for their support and determination to mold them into the stars we see on the field or court every season.

Many of the tweets included a sweet picture with mom, and words of encouragement for those taking on one of the world’s toughest jobs.

One of the notable exceptions was Los Angeles Lakers guard Kobe Bryant, who is currently in a legal battle with his mother Pamela over the rights to the superstar’s memorabilia. However, that could change as the day goes by.

Bryant did link to an Instagram pic of his grandmother earlier in the week: @KobeBryant My beautiful grandma #soalike #virgos #philly http://instagram.com/p/ZDwzLhxNle/

Former NFL wide receiver Chad Johnson also gave a shout to single mothers, pulling “double duty,” as he called it.
