David Goffin strikes a blow for the little guy by beating Marin Cilic in BNP Paribas Open

In the land of giants capable of unleashing thunderous serves that zoom across the court at 135 mph or more, 5-foot-11, 150-pound David Goffin stood tall and proud Thursday after reaching the semifinals of the BNP Paribas Open at Indian Wells.

The role of Goliath was played by 6-6, 196-pound Marin Cilic of Croatia, the 2014 U.S. Open champion renowned for 120-plus mph. serves. David was the aptly named Goffin, a 25-year-old Belgian who has speed, an admirably fluid game and, apparently, no fear.

"I knew that on my serve I had to battle to win every service game, because sometimes he can serve bombs and in 10 seconds can win his games," Goffin said.
