If this was a race, Showtime Boxing would have just lapped HBO Boxing, and a strong March will put it miles ahead of what used to be a competitive rivalry between the two networks.

Four events are scheduled to take place in March for Showtime, all featuring a strong headliner and undercard. It all starts with the heavyweights and it fittingly ends with them, too. It’s also a possibly historic month, with many of the scheduled boxers chasing history.

On paper, it’s one of the strongest months of boxing in history. Here’s what we have to look forward to.

March 3: Barclays Center in Brooklyn, N.Y.

Spotlight Fight: Deontay Wilder (39-0) vs. Luis Ortiz (28-0) for the WBC world heavyweight title

This fight was supposed to happen on Nov. 4, 2017, but it didn’t after Ortiz failed a drug test. Now, it is finally happening on Saturday. That is, unless the boxing gods are cruel and some unforeseen disaster strikes.

Ortiz is Wilder’s toughest level of competition and more than a formidable foe in Wilder’s quest for his 40th professional win.

Ortiz is 38 (we think). He is a slick boxer, a southpaw, and has true knockout power. A win for the Cuban would not be an upset by any means, and it would quickly stop all potential talk of Wilder fighting Anthony Joshua down the road.

Other key bouts: Andre Dirrell (26-2) vs. Jose Uzgetacui (26-2) for the interim IBF world super middleweight title, Sergiy Derevyanchenko (11-0) vs. Dashon Johnson (22-22-3), Alicia Napoleon (8-1) vs. Femke Hermans (6-0) for the women’s WBA super middleweight title, Willie Monroe Jr. (21-3) vs. Carlos Galvan (16-6)

March 9: Deadwood Mountain Grand in Deadwood, S.D.

Spotlight Fight: Regis Prograis (20-0) vs. Julius Indongo (22-1) for the interim WBC world junior welterweight title

It didn’t take long for Prograis to go from prospect to contender. His fight on ShoBox: The Next Generation in July 2017 against Joel Diaz Jr. opened everyone’s eyes. The three-round dismantling of Diaz led Prograis to a much bigger fight.

Prograis was originally scheduled to fight Viktor Postol, as mandated by the WBC, but Postol dropped out due to injury. Enter Indongo, the former IBF and WBA junior welterweight champion, who recently lost his first professional bout to Terence Crawford. For Indongo, it’s an opportunity to get back a title and wipe the memory of being knocked out by Crawford out of his head.

Other key bouts: Junior Fa (13-0) vs. Craig Lewis (14-1-1)

March 10: Freeman Coliseum in San Antonio

Spotlight Fight: Mikey Garcia (37-0) vs. Sergey Lipinets (13-0) for the IBF world junior welterweight title

Garcia is chasing history. A win over Lipinets will make him just the third boxer — the other two are Manny Pacquiao and Juan Manuel Marquez — to win a world title at the 126-, 130-, 135- and 140-pound divisions.

Lipinets will be there to try to make sure history is not made. The former kickboxer turned professional boxer earned the IBF title in his last bout when he defeated Akihiro Kondo by unanimous decision.

Another storyline going into this bout is that Garcia is still a “free agent.” A win will only increase his profile and the amount of promoters who will seek to sign the talented fighter. Heck, even UFC President Dana White met with Garcia recently. Zuffa boxing anyone?

Other key bouts: Rancel Barthelemy (26-0) vs. Kiryl Relikh (21-2) for the WBA world Junior welterweight title, Richard Comney (25-2) vs. Alejandro Luna (22-0), Mario Barrios (20-0) vs. Eudy Bernardo (23-2)

March 31: Principality Stadium in Cardiff, Wales

Spotlight Fight: Anthony Joshua (20-0) vs. Joseph Parker (24-0) for the IBF, WBA and WBO world heavyweight titles

The best heavyweight on the planet is back. The undefeated British superstar Joshua looks to claim another victim and title when he faces off against Parker. Joshua is coming off a 2017 in which he knocked out Wladimir Klitschko in a “Fight of the Year” candidate and also dropped Carlos Takam.

For Parker, this is the opportunity of a lifetime. He can dethrone the king of the division, become a multiple titleholder, and silence 65,000-plus Brits at the Principality Stadium in Cardiff.

Other key bouts: Alexander Povetkin (33-1) vs. David Price (22-4), Ryan Burnett (18-0) vs. Yonfrez Parejo (21-2-1)
