SOFIA, Bulgaria (AP) Fourth-seeded Andrea Petkovic reached the final of the season-ending Tournament of Champions by beating Spain's Garbine Muguruza 6-1, 6-4 on Saturday.
Petkovic dominated Muguruza at the start of the match and lost just five points on her serve in winning the first set in 24 minutes.
Muguruza got an early break in the second to go up 2-0 before Petkovic rallied to win five consecutive games. The Spaniard earned another break to cut the deficit to 5-4 but couldn't mount a comeback against the more experienced Petkovic.
Petkovic said ''I was glad I could serve really well in the end of the match and close it out there.''
Spain's Carla Suarez Navarro played Flavia Pennetta of Italy in the other semifinal.
