Target continued to sponsor Ganassi's operation through the decade, and by the mid part of the decade, the team had risen to the top of the series. Perhaps the most impressive was Juan Pablo Montoya winning the championship in his rookie season in 1999. They won four consecutive series championships, with Jimmy Vasser (1996), Alex Zanardi (1997–1998), and Montoya in 1999, becoming the first car owner to win four consecutive CART championships. In 2000, Ganassi became the first CART team to break ranks and return to race in the Indianapolis 500, part of the rival Indy Racing League. The team saw instant success as Montoya dominated the race. Montoya also became the first driver to win the Indianapolis 500 and the Michigan 500 in the same year since Rick Mears in 1991. However, he was unable to duplicate his championship success of 1999. Vasser's performance steadily dwindled, as his lone victory at Houston was his first in nearly two years.
