In Mortaza's absence through injury, Shakib led Bangladesh for the remainder of the tour. Aged 22 years and 115 days at the start of the second Test, Shakib became Bangladesh's youngest captain and fifth youngest in the history of Test cricket. Under Shakib's leadership Bangladesh went on to win the second Test, and in the process secured their first overseas series win. Individually Shakib performed well, earning both the player-of-the-match and player-of-the-series awards, scoring 16 and 96 not out with the bat and taking 3/59 and 5/70 with the ball. He scored 159 runs in the series at an average of 53.00 and was Bangladesh's second highest run-scorer for the series; his haul of 13 wickets at an average of 18.76 from both matches meant Shakib was the equal highest wicket-taker for the series along with West Indies fast bowler Kemar Roach. After winning the Test series 2–0, Bangladesh proceeded to whitewash the ODI series, winning 3–0. The West Indies' dispute remained unsolved for the whole of Bangladesh's tour and the West Indies continued to field an inexperienced side. Shakib collected two half centuries in the ODI series, averaging 45.00, and was the third highest run-scorer in the series; he also took 2 wickets at an average of 48.00. For his performance in the ODIs, Shakib was named the man of the series.
