Wolff says he must protect Hamilton after Imola low

IMOLA, Italy: Mercedes team boss Toto Wolff has promised to protect Lewis Hamilton after the seven times Formula One world champion struggled through Sunday's Emilia Romagna Grand Prix.

Hamilton is now seventh overall, already 58 points behind Ferrari's leader Charles Leclerc and with his title hopes in tatters.

Wolff said the true greats all had difficult moments in their careers and overcame them, and Hamilton, winner of a record 103 races, would do so too.

Wolff said the team still
