Suryakumar Yadav is an antithesis to what proverbial Mumbai school of batsmanship is all about -- dollops of doggedness in a fine mixture of style and class. Style and class has never been a problem with 'SKY'. He has given ample display of that in T20 cricket, a format he has bossed with remarkable ease. However some of his low scores in ODIs did raise questions if he is unable to blend a bit of serenity in his all or nothing approach, which is perfectly in sync with T20s but not the 50-over format.
