Pollard's impressive performance in the
2009 Champions League Twenty20 and the
Big Bash led to him being one of the most sought after players at the
2010 IPL auction. After some aggressive bidding, the
Chennai Super Kings,
Kolkata Knight Riders,
Mumbai Indians and
Royal Challengers Bangalore all bid the maximum allowed; $750,000. A 'silent-tiebreaker' was won by the Mumbai Indians. On 15 November 2022, Pollard announced his retirement from IPL after playing for Mumbai Indians for 13 seasons. Now he is appointed as batting coach for Mumbai Indians.
2010 Kieron Pollard made his debut for
Mumbai Indians on 17 March 2010 against the
Delhi Daredevils at Feroz Shah Kotla in Delhi. It took a while for him to get off the blocks in his first season. He however proved his money's worth in the latter stages of the tournament with a blistering 13 ball 45 laced with 5 sixes and accounted for 2 run outs earning him his first MOTM performance. This was followed by a stellar performance against the
Royal Challengers Bangalore in the semi-final. Pollard smashed a quick fire 33* off 13 balls with 3 sixes and followed it up with 3 wickets and 1 run out. He was adjudged man of the match and his efforts propelled
Mumbai Indians into the final for the first time where they eventually lost to the
Chennai Super Kings.
2011 and 2012 2010 season was followed by 2 mediocre seasons for Pollard. In 2011 the only highlight was his brilliance in the field. In 2012 a sole Man of the match performance against
Rajasthan Royals where he smashed a 33 ball 64 with 6 4s and 4 6s and followed it up with a career best 4-44in the 2nd innings.
2013 Pollard started the season strongly with a stellar knock of 57* off 38 balls with 5 sixes when Mumbai had lost early wickets and in the 2nd innings he picked up 1 wicket and a superb catch by
MS Dhoni ensured
Mumbai Indians victory. He was adjudged MOTM for his all round performance. Against Royal Challengers Bangalore he propelled Mumbai to a competitive score with a 16 ball-34. Arguably one of Pollard's best performances came against Sunsrisers Hyderabad. With over 60-odd runs to chase in 4 overs, Pollard joined skipper Rohit Sharma and lit the Wankhede up with a splendid 66* off 27 balls. He hit 6 sixes in a span of 7 balls and led Mumbai to an emphatic victory. Pollard saved his best performance for the final against Chennai. With Mumbai reeling at 52–4 Pollard fought back with a 60* off 32 balls to lead Mumbai to a competitive score of 148. In the 2nd innings he picked 1 wicket and Mumbai won their 1st IPL title.
2014 Mumbai Indians got off to a disastrous start losing their first five games in UAE. Pollard smashed 78 off 48 balls whilst chasing against SRH but he was dismissed by
Irfan Pathan in the last over and Mumbai eventually lost the match. In the first game at Wankhede against Punjab Pollard chipped in with a crucial 28 off just 12 balls and helped Mumbai register their first win of the season.
2015 This can be rightly called as Pollard's best season till date. Similar to 2014 Mumbai had a forgettable start to the season managing only 1 win out of the first 6 matches. Pollard struck 70 runs off 48 balls with 7 boundaries and 5 sixes against Rajasthan but Mumbai lost the match. He followed it up with another 64 runs off just 34 balls smashing 5 sixes against Chennai but again Mumbai were unable to defend their total. Chasing against the Delhi Daredevils Pollard joined Rayudu and smashed a quck-fire 26* off just 14 balls and ensured victory. In the same week, he smashed 49 off just 24 balls with 6 sixes but Mumbai were unable to chase RCB's mammoth total. In a must win game against Kolkata Pollard played a patient knock with Hardik Pandya and helped Mumbai reach 171.
Yusuf Pathan led the KKR chase with a brilliant half century and the equation was 12 runs required off the final over. Pollard with ball in his hand dismissed Pathan on the very first ball, conceded 6 runs in the next 2 balls but followed it up with 3 dot balls to help Mumbai to a crucial victory. In the first qualifier at Wankhede against the Super Kings Pollard helped Mumbai post a massive total of 187 with 17 ball 41 with 5 sixes and helped Mumbai reach the final. In the final against the same opposition at Eden Gardens, Pollard added 36 off just 18 balls and helped MI reach a massive total of 202. Mumbai Indians defeated Chennai to win their 2nd IPL title. Pollard ended the tournament with 419 runs at SR of 163 and 28 sixes.
2019 Pollard did not have the best of IPL in this one. However he played a couple of crucial innings for his team, once again
Mumbai Indians. In a low-scoring match against the
Sunrisers Hyderabad, Mumbai were asked to bat first and had lost their top 3 inside the first 10 overs. From the 17th over onwards, Pollard started his massacre when he hit 4 sixes and 2 fours in that span to make a 46* off 26 balls, and get Mumbai a defendable total of 136, given their bowling. Mumbai bundled out Hyderabad for 96 runs where
West Indian bowler Alzarri Joseph took 6 wickets for 12 runs in debut. Then, in a match against
Kings XI Punjab, wherein Punjab gave them a target of 198 in 20 overs. Mumbai did not have the best of starts with not even 70 runs on the board after 11 overs, at the loss of 4 wickets. Pollard then took it upon himself wherein he made 83 runs off just 31 balls, which included 10 sixes and 2 fours, and ensured Mumbai did not fall short of the target even after his dismissal. In the final against
CSK, he smashed a 41* of 25 deliveries, to ensure that Mumbai reached a somewhat respectable total of 149 in their allotted 20 overs. They ultimately won the tournament after a sensational final over spell by teammate
Lasith Malinga, where he defended 9 runs of the final over, producing a wicket of the final delivery where 2 runs were required. He was named the ‘Super Striker of the match’.
2020 In his 11th consecutive year playing for the
Mumbai Indians, Pollard became the first player to represent the franchise in 150 matches. Pollard played a critical role in the team winning their 5th IPL title. He was named the 'Super Striker of the Season' in IPL 2020.
2023 After having an ordinary season in 2022, the team was supposed to release a list of retained and released players. Due to his underperformance the previous season, he decided to retire from the IPL. Since he wasn't retained, Pollard didn’t want to play against MI and made the difficult decision to step away from the game. ==Other franchise leagues==
