Sachin Tendulkar struck his 51st Test century for India to counter an inspired spell from Dale Steyn and leave the third and deciding Test against South Africa evenly poised after day three.
Tendulkar stroked an elegant 146 as India were bowled out for 364, a lead of just two. Harbhajan Singh then claimed two late wickets as the hosts reached 52-2 in their second innings. The series is tied 1-1. Tendulkar -- who scored seven Test centuries last year -- brought up his hundred after lunch by top-edging a hook off Morne Morkel for six.
He took India from 28-2 to 341-8 before his 314-ball stay was ended by a fine delivery from Morkel, who beat him with a ball that was angled in before nipping away to hit the top of off-stump.
Rafael Nadal and Roger Federer both got their 2011 campaigns off to comfortable starts with straight-sets victories in the opening round of the ExxonMobil Open in Doha.
Nadal was far too strong for Slovakian Karol Beck, reeling off the last seven games of the match to score a lop-sided 6-3 6-0 victory over the world No 103 in just 69 minutes.
Federer was detained marginally longer, taking 78 minutes to dispose of plucky Dutch qualifier Thomas Schoorel, who pushed the world No 2 to a first-set tie-break before going down 7-6 (7-3) 6-3.
