Ginebra–Shell rivalry

The Ginebra–Shell rivalry is the early 1990s PBA rivalry that followed the San Miguel–Purefoods rivalry and Añejo–Purefoods rivalry and probably the decades' best rivalry before Sunkist and Alaska battled in the PBA championship for three straight conferences in the mid-1990s.

Finals match-up
The two teams played in the PBA championship in the first conference of the 1990 and 1991 season, Shell won their first title and prevailed in six games when Ginebra, then Añejo Rum 65, walked out in the second quarter of Game Six of the 1990 First Conference finals. The following year in the same conference, Ginebra San Miguel exact revenge, coming back from a 1-3 series deficit and won in Game Seven on Rudy Distrito's difficult drive to the basket in the last five seconds of their epic encounter.

Semifinal series & playoff games
The 1996 knockout match between Shell and Ginebra for the right to play Alaska Milk in the finals of the Commissioners Cup remains the most-talked about playoff matches among old-school PBA fans. The Zoom Masters won that game on import Kenny Redfield's three-point shot at the buzzer. Two years before in the 1994 PBA Governor's Cup, Shell knock Ginebra (then known as Tondeña 65) in a playoff for the last semifinals berth.

Ginebra and Shell would renew their rivalry during the semifinal series of the 1999 PBA All-Filipino Cup. The Ginebras, now known as Barangay Ginebra Kings and coming off an upset win over top-seeded Mobiline Phone Pals, lost to Shell in the best-of-five series via 3-0 sweep. The series win by the Zoom Masters, earn the team their first All-Filipino finals appearance since their maiden year in 1985. Significantly, Shell defeated Ginebra in a knockout game that time to make it to the finals.

Two year later in the 2001 PBA All-Filipino Cup, Barangay Ginebra this time won over Shell in the best-of-five semifinal series, three games to two, for their first finals stint since 1997. The Gin Kings' victory enabled Jun Limpot to finally play in his PBA finals after 8 seasons. Likewise Vergel Meneses will be making his first finals trip in five years since his Sunkist Orange Juicers days.
