Nadal moves into Stuttgart final

Stuttgart, Germany (Sports Network) - Top-seeded Rafael Nadal advanced to the final at the Mercedes Cup after posting a victory in the semifinals on Saturday.
Nadal, who won this title in 2005, defeated fellow Spaniard Feliciano Lopez, 6-1, 7-5. Nadal has now won 92 of his last 93 matches on clay and is aiming for his sixth title of the year and 23rd overall.
Nadal will meet Stanislas Wawrinka of Switzerland in Sunday's final after Wawrinka upset seventh-seeded Juan Ignacio Chela of Argentina 6-7 (2-7), 6-4, 6-1.
Wawrinka has just one ATP title to his credit, capturing the crown last year in Umag.
Nadal and Wawrinka have met just once before with the Spaniard winning at this year's Australian Open.
