Opening the innings for Chennai Super Kings, Watson scored a century off 51 balls and became the second centurion in this IPL. Watson and Rayudu for the first wicket scored 50 runs in just 27 balls before Rayudu got out in the fifth over. Raina joined Watson in the middle and they put together 81 runs in 44 balls. Even as the wickets were falling at the other end, Watson batted steadily and reached the century mark in the eighteenth over. Before getting out on the penultimate ball of the match, he ensured that CSK reached the 200 mark.Here are some of the twitter reactions to Watson's century:Now ..I Can Say Watson Is Best Buy in Entire IPL this Year *Perfect With The Bat *Gives 4 Over With The Ball #CSKvRR— ROMEO 2.0🍭 CSK (@imsamkhiladi) April 20, 2018Watson scored a hundred previously for #RR against #CSK (in 2013)He now scores a hundred for #CSK against #RR3rd #IPL hundred for the Australian veteran#CSKvRR #IPL2018 pic.twitter.com/R5kzbbypBh— Cricbuzz (@cricbuzz) April 20, 2018KL Rahul, Chris Gayle and Shane Watson performing like there's no tomorrow after RCB kicked them away.
