Tyrrell struggled on through the 1980s and 1990s – the team consistently punching above their financial weight following the 1984 controversy, despite winning the Colin Chapman Trophy for naturally-aspirated constructors in 1987 following Renault's withdrawal that year. There was a brief revival of fortunes in the early 1990s. The combination of Harvey Postlethwaite's revolutionary anhedral high-nose Tyrrell 019 and Jean Alesi's full debut season in 1990 brought the team two second places at Phoenix and Monaco – Alesi having led 30 laps of the Phoenix race. The French-Sicilian left the next year for Ferrari, but Honda engines and Braun sponsorship in 1991 helped Stefano Modena earn a front row start at Monaco alongside Senna and a fine second-place finish at the 1991 Canadian Grand Prix. Nonetheless, the team slowly dropped back from the middle of the pack. Eventually, in 1998 and in the face of dwindling form and ill health, Ken sold his team to British American Tobacco, the team becoming British American Racing. Tyrrell's last F1 points were scored by Mika Salo at the 1997 Monaco Grand Prix. The final race for Tyrrell was the 1998 Japanese Grand Prix, where Ricardo Rosset failed to qualify and teammate Toranosuke Takagi retired on lap 28 after a collision with Esteban Tuero's Minardi. Ken himself left the team following the sale, just before the start of the 1998 season, after disagreement with new team principal Craig Pollock over him choosing Rosset for sponsorship money reasons over Jos Verstappen.
