Alexander Zverev said it felt "very special" to become just the fifth player to reach the semi-finals of all nine ATP Masters 1000 tournaments and join elite company after he booked his place in the last four at Indian Wells.
The German claimed a confident 6-2 6-3 victory over Frenchman Arthur Fils to reach the last four of the California-based tournament for the first time.
By completing the set of Masters 1000 semi-final appearances, Zverev joins a club featuring only tennis' 'Big Four' - Roger Federer, Rafael Nadal, Novak Djokovic and Andy Murray.
"It's very special to be one of five players in history to ever do it," Zverev said.
