Kolkata Knight Riders and Delhi Daredevils were the winners of one-sided games of the Indian Premier League Tuesday. Pace bowler Lakshimpathy Balaji's haul of 4-18 helped Kolkata score a 42-run victory over Bangalore at the Chinnaswamy Stadium, while England batsman Kevin Pietersen smashed a quick 43 not out to guide Delhi to an eight-wicket win over Chennai Super Kings at the Ferozeshah Kotla in New Delhi. Kolkata scored 165-8 and restricted Bangalore to 123-9. South Africa all-rounder Jacques Kallis (22 and 2-7), captain Gautam Gambhir (64) and Manvinder Bisla (46) were the other main performers apart from Balaji. For Delhi, a spate of run outs helped restrict Chennai to 110-8. Delhi scored 111-2 in only 13.2 overs. Kolkata made a superb start after being put in to bat, but faltered in the latter half of its innings when a total of close to 200 looked likely. After Kallis' steady innings was brought to an end by Bangalore captain Daniel Vettori, Gambhir and Bisla added 64 in less than eight overs. Sri Lankan spinner Muttiah Muralitharan, Zaheer Khan and Vinay Kumar took two wickets each as Kolkata slipped from 125-1 in the 14th over. Manoj Tiwary, Yusuf Pathan, Ryan ten Doeschate and Shakib Al-Hassan all failed to get into double-figures. In reply, Bangalore failed to recover from the early wickets by Kallis and Balaji was later well supported by all-rounder Rajat Bhatia in the middle of the innings to mount pressure on the batsmen. Bangalore was 33-5 in the 10th over. A brief resistance by Vettori (20) was brought to an end by Balaji in his final over. Vinay Kumar threw his bat around for 25 off 26 balls but the contribution was too little too late.
