Pakistan cricket captain Sarfraz Ahmed vowed Tuesday to be a better player as he returned home after being handed a four-match ban for a racial slur against a South African player in Durban last week.

The 31-year-old was heard on a stump microphone making a comment in Urdu about Andile Phehlukwayo during the second one-day international. The International Cricket Council (ICC) on Sunday banned Sarfraz for four matches -- two one-day internationals and two Twenty20 internationals -- of the South African tour. The Pakistan Cricket Board (PCB) expressed disappointment over the punishment -- saying it believed a ban was unnecessary because the matter had already been resolved between the two players -- and withdrew the Pakistan captain from the tour.
