RANCHI:Chennai Super Kings sauntered through to the Champions League semi-finals with an effortless eight-wicket win in Ranchi,while scuttling Brisbane Heat's tournament hopes.A stuttering Heat top order laid a mediocre foundation,before the men in the middle ran aground on Super Kings'spin.Ravichandran Ashwin was almost indecipherable in the middle overs,but Ravindra Jadeja and Suresh Raina contributed fine spells as well;the trio shared four wickets and conceded just 37 runs in 11 overs collectively.Michael Hussey then stroked an unhurried,unbeaten half century,to help run down the target of 138 in 15.5 overs.On a decent batting pitch,and with dew collecting on the outfield, 137 for 7 would rarely have been a base forvictory,and at no stage in the chase did it test a purring Super Kings batting order.Hussey and Vijay punished indiscipline,but the pair were largely content to push runs into the outfield when the bowlers found their line.
