Julio César Chávez vs. Meldrick Taylor, billed as Thunder Meets Lightning, was a professional boxing match contested on March 17, 1990, for the WBC and IBF light welterweight championship.

Chavez won the fight by a controversial TKO of Taylor only two seconds before the end of the twelfth and last round, while he was behind on the score cards.

Julio César Chávez had an undefeated record of 68–0 with 55 wins by knockout and had won world championships in three weight classes: super featherweight, lightweight and, the previous year against Roger Mayweather, the WBC light welterweight title.

Taylor's hand and foot speed and boxing abilities gave him the early advantage, allowing him to begin building a large lead on points.

Finally, with 25 seconds left, Chávez landed a hard right hand that caused Taylor to stagger forward towards a corner.

Referee Richard Steele then asked Taylor twice if he was okay, received no reaction and then signaled that he was ending the fight, resulting in a TKO victory for Chávez with only two seconds to go in the bout.

On May 15, 2009, Taylor released a book titled "Two Seconds From Glory" detailing the fight with Julio Cesar Chávez along with other controversial subjects.
