Ramon Sadaya Fernandez (Tagalog: [raˈmon feɾˈnandes]; born October 3, 1953) is a Filipino former professional basketball player and current commissioner of the Philippine Sports Commission.

He played for five teams in his entire PBA career starting with the Toyota, Manila Beer, Tanduay, Purefoods and San Miguel.

With his teammates, Robert Jaworski, Francis Arnáiz, Arnie Tuadles, Danny Florencio, Emerito "Emer" Legaspi and Abe King, Toyota won nine titles from 1975-1983.

From 1986-1987, Fernandez along with former Crispa rivals Freddie Hubalde and Padim Israel, J.B. Yango, Willie Generalao, Onchie dela Cruz and imports Rob Williams, Andre McKoy and later, David Thirdkill, led the Rhum Masters to three PBA titles.

The highlight of the event was the kick out pass of Fernandez to Jaworski, who sank a three-pointer to seal the Tamaraws' 65–61 win over their bitter rivals, the Redmanizers.

He also ventured in several business opportunities and is currently based in Cebu, managing his flourishing "Suka ni El Presidente" brand of bottled spiced vinegar.

Fernandez could actually play all five positions on the basketball court, having mastered the skills needed as a point guard, off-guard, forward, power-forward and center.

He is known for his dribbling skills (unusual for a center during his era), uncanny passing ability, perimeter jumpers, and unstoppable high or low post moves.

Almost always, whenever he would get the defensive rebound he would assume the role of "point-center", leading the fast-break (a throwback to his point-guard days), which he admitted was a habit he could not break in the pros.

Fernandez would dribble the ball running the middle of the court, either hitting the open man on either wing or finishing a lay-up with either hand.

He had an ambidextrous hook shot that was almost impossible to stop and a weird-looking variation of a lay-up that was executed while "fading away" from the basket which made it equally intriguing.

He did this in front of a capacity crowd on May 30, 2003 during the Crispa Redmanizers vs. Toyota Super Corollas Reunion game at the Smart Araneta Coliseum.

With Toyota up 37-29, Fernandez intercepted a pass from Bernie Fabiosa underneath the Crispa basket, dribbled with his left hand, crossed-over a defending Atoy Co, brought the ball down the full length of the court with his right hand and just after entering Toyota's shaded lane shovelled the no-look pass to teammate Rolly Marcelo on the right side for an unmolested layup.

His pinpoint passing ability was so devastating to opponents because he often executed them at critical junctures of the game, either coming from his right or left hand.

Philip Cezar and Abe King, two premier defenders of local players and imports alike, in television interviews, always said that Fernandez was the toughest assignment they ever had to handle.

But these limitations were offset by the fact that he had an array of astonishing skills, a basketball IQ that was off the charts and mental toughness that enabled him to impose his will against opponents.

Case in point: Fernandez, even on a bad night, could still cut down an opponent, by baiting him into senseless fouls or getting him to react in an unsportsmanlike manner to many pre-designed tirades.
