Lehmann, who left the Indian tour mid-way due to a hamstring injury, was conferred the honour for his purple international patch in the latest Wisden issue, according to an Australian website.
The South Australian, who missed the first half of the last Australian summer due to Achiles tendon injury, came back strongly to score 686 runs, including two centuries and five fifties, at an average of 45.73 in eight Tests -- five against Sri Lanka and three versus India.
The 34-year-old also made a mark as a part-time spinner with impressive figures of 3-50 and 3-42 in the third Test in Colombo, a game in which he also made 153.
In the One-Day Internationals, Lehmann's five innings in eight games have earned him 173 run at an average of 34.6, with a top score of 67 against Zimbabwe in Harare.
Lehmann has also claimed eight wickets, including 4-7 in his man of the match effort in Harare.
