Garcia (34-2, 20 KOs) has fought and defeated many of the most formidable opponents at 140 and 147-pounds spanning two generations-Erik Morales, Zab Judah, Kendall Holt, Amir Khan, Lucas Matthysse, Paulie Malignaggi and Lamont Peterson among them.
Six of his seven opponents in the welterweight division were former or current world champions and 12 of his last 16 opponents overall carried the same distinction.
Included in that run was a headlining performance in January 2016, when he defeated Robert Guerrero to capture his welterweight title in Los Angeles. Representing the fighting city of Philadelphia, the 30-year-old most recently lost an exciting and narrow decision to Shawn Porter in their September title fight.
"I cannot wait to get back in the ring and put on the Danny Garcia show once again," said Garcia.
"Granados was talking a big game when we first announced the fight and I plan on proving him wrong on April 20. "The Southern California fans have always treated me right and I'm excited to give them a great fight."
Fighting out of Cicero, Ilinois, Granados (20-6-2, 14 KOs) has made a name for himself by delivering tough, action-packed fights against top fighters in the sport, including Shawn Porter and Adrien Broner.
The 29-year-old burst onto the scene by shocking then unbeaten Amir Imam via a stoppage victory in their 2015 clash. After a fight last June against Javier Fortuna that ended in a no contest, Granados picked up two-straight knockout wins heading into this matchup.
"This is a huge fight for me and definitely one of the most important in my career," said Granados. "I'm looking to dominate, look impressive and control the fight.
"I've fought in Southern California before and I'm looking to take advantage of the great Mexican crowd. "This is Mexico versus Puerto Rico and Chicago vs. Philadelphia. It's territorial on a lot of levels and you can expect us to leave it all in the ring."
