Here is a look at the statistical highlights from Day 1:

# Ashwin (26 at 19.65 runs apiece) is the seventh Indian bowler to capture 25 wickets or more in a Test series against Australia, joining Harbhajan Singh (32 at 17.03 in three Tests in 2000-01), Bishan Singh Bedi (31 at 23.87 in five Tests in 1977-78), Bhagwat Chandrasekhar (28 at 25.14 in five Tests in 1977-78), Anil Kumble (27 at 25.37 in four Tests in 2004-05), Dilip Doshi (27 at 23.33 in six Tests in 1979-80) and Erapalli Prasanna (26 at 25.84 in five Tests in 1969-70 and 25 at 27.44 in four Tests in 1967-68). Prasanna is the only Indian spinner to accomplish the feat twice against Australia.
