Mumbai Indians captain Rohit Sharma agreed with the team’s decision to leave Kieron Pollard out of the squad ahead of Thursday’s encounter against Chennai Super Kings.Similar to former West Indian teammate Chris Gayle last year, Pollard was left out of the line-up on his 35th birthday.  Instead, the team opted to go with South Africa big-hitter Tristan Stubbs on debut.Despite it being a special day for the West Indian, few could have disagreed with the decision considering the player’s recent form.  In 11 IPL matches so far, the big West Indian has scored just 144 runs at an average of 14.40 and with a strike rate of 107.46.  The ball-striking tally is the player’s lowest since he made his debut in the IPL in 2010.In explaining the decision, Sharma insisted the team, which is currently bottom of the IPL, has begun to contemplate its future.
