DURBAN, South Africa, Jan 10 (Reuters) - Graeme Smith stroked a fluent 13th test century to keep South Africa on top in the third and final test against West Indies on Thursday.

South Africa were 213 for one, a lead of 74 runs after they had bowled out the tourists for 139, when bad light ended play 10 overs early on the first day.

Smith reached 122 not out in a chanceless innings, sharing an unbroken stand of 160 with Hashim Amla (55 not out) to record South Africa's highest second-wicket partnership against West Indies.

Recalled seamer Shaun Pollock, who was left out of South Africa's first six tests of the season, led the home side's attack with his return of four for 35.

"The cloud cover in the morning made the ball swing and that helped us," Pollock told a news conference.

"We had the better of the conditions. If we hadn't made early inroads it could have been tough work for us."

Fast bowler Dale Steyn made the initial breakthrough when he had Daren Ganga caught by Smith at first slip for three.
