"I left before the start of the 1st inning," Fishel tells TMZ Sports ... "I had been up since 3AM doing press [for the show]."
Despite the fact she was with Ben Savage to throw out the first pitch, "Girl Meets World" star Danielle Fishel says she MISSED Clayton Kershaw's historical no-hitter ... BECAUSE SHE LEFT EARLY!!!!
There were rumors that Danielle and Ben peace'd out in the 4th -- but D.F. says it's not true ... she left WAYYY before that.
But Fishel says the fact she boned out early is a good thing for Dodgers Nation -- "Kershaw achieved something amazing. If I had stayed, I may have jinxed him."
Danielle explains ... "I missed a chance to see history, but I live in Orange County and I have a husband and a dog and other responsibilities that come before having a good time at a Dodgers game, unfortunately."
"I did everyone a favor because the stars aligned for the Dodgers that night."
