Following her collegiate career, Taurasi was selected first overall in the
2004 WNBA Draft by the
Phoenix Mercury, a team that went 8-26 in the
2003 season.
Taurasi netted 26 points and led the Mercury to an 84-76 victory over the
Seattle Storm in her WNBA debut. For the season, the rookie averaged 17.0 points, 4.4 rebounds and 3.9 assists per game. Although the Mercury did not qualify for the playoffs, the season was a personal success as Taurasi was named to the Western Conference All Star team and won the
WNBA Rookie of the Year Award.
In
2005, Taurasi averaged 16.0 points, 4.2 rebounds and 4.5 assists per game while battling an ankle injury. She was an All Star for the second straight year, but the Mercury faded down the stretch and again missed the playoffs.
Former
NBA coach
Paul Westhead became the Mercury's head coach prior to the
2006 season and brought his up-tempo style to Phoenix. Their roster was further bolstered by the addition of rookie
Cappie Pondexter, the #2 overall selection in the
2006 WNBA Draft.
Taurasi flourished under Westhead's system, leading the league in scoring and earning a third straight trip to the All Star Game. She broke
Katie Smith's league records for points in a season (741 during the
2006 season) and in a game (47 vs.
Houston on August 10). In 2006, Taurasi averaged a record 25.3 points, 4.1 assists and 3.6 rebounds per game. The Mercury finished 18-16, but lost a tie-breaker with Houston and Seattle and missed the playoffs.
In 2007, Taurasi got her first taste of the WNBA playoffs. In the first round, her Mercury eliminated the
Seattle Storm 2 games to none. Next, they took down the
San Antonio Silver Stars in a hard fought two game series. Taurasi got to her first
WNBA Finals, but had the defending champion
Detroit Shock in her team's way. After a hard-fought series, Diana and Pondexter led the Mercury to their first WNBA title. With this victory Taurasi became just the sixth player ever to win an NCAA title, a WNBA title as well as an Olympic gold medal. The others to achieve this trifecta are
Ruth Riley, Sheryl Swoopes, and fellow Huskies
Swin Cash, Kara Wolters, and
Sue Bird.
