Here's the quote.
The Sith Lord was borne backward by the Jedi Knight's initial rush, caught off guard by the other's wild assault, and pressed all the way back to the far wall of the melting pit. There he struggled to keep the young Jedi at bay, trying to open enough space between them to defend himself. Lightsabers scraped and grated against each other, and the chamber echoed with their fury. Lunging and twisting, Darth Maul regained the offensive and counterattacked, using both ends of his lightsaber in an effort to cut Obi-Wan's legs out from under him. But Obi-Wan, while not so experienced as Qui-Gon, was quicker. Anticipating each blow, he was able to elude his antagonist's efforts to bring him down.
