Austrian Thiem, who was also briefly ranked fourth in the world in late 2017, rose four places after beating Federer 3-6, 6-3, 7-5 on Sunday to deny the Swiss star a record sixth Indian Wells crown.
Federer, 37, dropped one spot to fifth as the top three remained unchanged with Novak Djokovic ahead of Rafael Nadal and Alexander Zverev despite the Serb’s third-round exit in California.
Nadal, who pulled out of his semi-final with Federer due to a knee injury, will skip this week’s Miami Masters as he targets a return to competition for the clay-court season.
Juan Martin del Potro dropped three spots to eighth after he was unable to defend his Indian Wells crown because of a knee problem. The Argentine will also miss the Miami event.
