Shell Turbo Chargers (1989–2002)
Drafted by the Shell Turbo Chargers in 1989 with the first overall pick, Paras began his PBA career. Being drafted by Shell reunited him with Magsanoc once again. Together with import Bobby Parks, they led Shell to the finals of the 1989 Open Conference, where they lost to the eventual Grand Slam champions San Miguel Beermen. He then made his first appearance at the All-Star Game that season, although his team lost as Mon Fernandez scored the game-winner over him. Although Shell did not win any titles that season, his abilities were on full display as he averaged 25.8 points in 57 games, the most by a PBA rookie. He also scored 50 points twice that season, a point off the all-time mark of 51 for most points scored by a rookie, and a record held by Dennis Abbatuan since 1984. He also averaged 13 boards, and 2.6 blocks. Because of these he not only took Rookie of the Year, but also became its Most Valuable Player. As of 2026, he is the only PBA player to have accomplished this feat.
In 1990, Paras would lead Shell to their first PBA title during the First Conference by defeating Anejo Rhum in a championship series that finished in six games, in a climax that featured a walkout by Anejo players. He also made the All-Star team that season. In 1991, Shell and Anejo (now known as Ginebra) would meet again in the finals of the Reinforced Conference. The Turbo Chargers seemed poised to beat the Gins once again after taking a commanding 3–1 lead, but the Gins made a dramatic rally, coming back from the 3–1 deficit and winning the title in a classic Game 7 encounter that featured Rudy Distrito's game winner.
In 1992, Paras and the rejuvenated Turbo Chargers, now with Leo Isaac and Rey Cuenco, led Shell to another title, winning the 1992 First Conference over the Beermen. After the 1992 title, Paras and Shell would show inconsistencies as it flirted to the cellars in several occasions. This was also capped with a controversy back in 1993 when Paras sat out for one conference after a contract dispute with Shell that prompted him to demand a trade deal to rival team Ginebra. During this time, he lived with Robert Jaworski, and relied on him for his allowance. But after Shell rejected trade offers for their prized center, he decided to concentrate on his movie and TV career for six months.
Paras came back to the team in the 1993 Commissioner's Cup, but the team did not made it back to the finals for a long time. They did make the semifinals in the 1994 Governors' Cup, and in the 1995 Governors' Cup, in which they denied the Sunkist Orange Juicers a grand slam. In the 1996 Commissioner's Cup, they made it back to the finals thanks in part to import Kenny Redfield and supporting casts such as Peter Naron, Richie Ticzon, Victor Pablo, and Jojo Lim. They battled the grand slam seeking Alaska Aces, then known as the Alaska Milkmen, in a seven-game series which Alaska won. Paras was also a contender to win the MVP in the 1996 season of the PBA.
Paras missed most of the 1997 Commissioner's Cup due to surgery on his knee. He would re-enter the finals two years later in the 1998 Centennial Cup Finals, this time meeting the Mobiline Phone Pals. In a one-game title showdown, Shell came up short. Paras would get his revenge thanks to the help of Noy Castillo and Gerry Esplana as the rematch was set for the Governor's Cup finals of the PBA against Mobiline. Shell came back after trailing the series 3–2. Shell and Mobiline battled into a grueling seven games until Shell prevailed due to timely baskets by Paras and Esplana.
In 1999, in a season which saw the influx of Filipino-American talent, some of whom were only faking to be Filipino-American, Paras dominated the league once again. He led Shell past San Miguel in the quarterfinals and Ginebra in the semis to another finals appearance in the All-Filipino Cup, this time against the Tanduay Rhum Makers. They were bannered by Fil-Am Eric Menk, who had just won Best Player of the Conference over him, and Sonny Alvarado, who would eventually be deported. He held his own against the two taller, stronger and more athletic Fil-Ams as he led Shell to another title, winning it 4–2. That would be Paras' last title, as his team was unable to stop the Beermen in the title showdown for the Commissioner's Cup. He also won the All-Star Game MVP that season, leading the Veteran All-Stars over the Rookies and Sophomores team. During the Governors' Cup, on November 10, he reached the 10,000 point milestone. At 31 years old, Paras would win his second MVP since 1989. He also won the Comeback Player of the Year award that season.
During the 2000s, Paras played in only 44 games due to injuries. In 2001, he re-signed with the team for a max deal of P25 million for two years. However, he was only able to play in eight games during the 2002 season. Due to his injuries, in 2003, days before the season started, he decided to retire, serving the remainder of his contract on Shell's coaching staff. Shell retired his #14 jersey.
