New Delhi: The Indian Premier League season five has been most unpredictable in the tournamentâs history. Going by the results so far, itâs been a season where big scores have been no guarantees of wins. Five games have been lost by sides after scoring 170 or more runs.The team that set the tone was the Mahendra Singh Dhoni-led Chennai Super Kings. Chasing a target of 206 set by Royal Challengers Bangalore, Chennai lost their way in the middle overs but a quickfire 28 from seven balls by South Africa allrounder Albie Morkel got them over the line.Bottom-placed Deccan Chargers found themselves on the losing side on three occasions. The latest being their losing to Delhi Daredevils after putting 187 for 4 on the board. A breathtaking century from Australia opener David Warner (109 not out of 54 balls) denied the whipping boys of the season a win.In Deccanâs match against Rajasthan Royals, their target of 197 was not enough as the Rahul Dravid-led side, with the help of Brad Hodge (48 of 21), chased down the score with two balls to spare.Chris Gayle massacred Pune Warriors Indiaâs hopes of winning by scoring a 48-ball 81 with eight sixes and four fours. Gayle sent Rahul Sharma running for cover as he smashed five massive sixes in his over to change the course of the game. AB de Villers (33 of 14) picked up runs at the end and Saurabh Tiwary (36 of 23) hit a six off the last ball as Daniel Vettori's team chased down 183 for victory. Bangalore again found themselves in the riding seat when they defeated Deccan (182 for 2) by five wickets. de Villers, scoring a 17-ball 47, sealed the match in 19th over. Clearly, no score has been safe. Thatâs one of the reasons why the tournament has never been this open before.
