Two additional Twenty20 internationals have been added to the itinerary for Pakistan's upcoming tour of the West Indies.
The two teams were set to meet in two T20s in the Caribbean, prior to three one-day internationals and three Tests.
However, the West Indies Cricket Board (WICB) confirmed on Saturday that four T20s will now be contested, with extra matches taking place in Barbados and Trinidad.
The series will begin in Barbados on March 26.
"Twenty20 is an exciting format and this is another opportunity for our fans to indulge in the thrilling atmosphere that surrounds these matches," said Roland Holder, the WICB's manager of cricket operations.
"We look forward to fans in Barbados and Trinidad coming out and cheering our team on to victory."
The Windies are currently hosting England in a three-match ODI series. The second match takes place in Antigua on Sunday, with England 1-0 up following a 45-run win at the same venue.
