Jason Holder lauded the "inspirational" performances of Darren Bravo and Devendra Bishoo, despite West Indies falling to a 56-run loss against Pakistan.
Asia's maiden day-night Test, and the first of a three-match series between the two sides, proved memorable as the Windies fought hard to keep the contest going right to the death.
Having seen their opponents declare on 597-3 in the first innings, Holder's side were all out for 357 before Bishoo's stunning 8-49 helped to skittle Pakistan for 123 the second time around.
Chasing 345 to win, Bravo's 116 helped West Indies to make a match of it, but Pakistan finally got the job done with 12 overs remaining on the final day in Dubai.
"It was a good fight, but I'm still disappointed we didn't get over the line," said captain Holder. "Bishoo's spell and Bravo's knock were inspirational.
"[There were] definite signs of improvement. We always wanted the two batsmen at the crease to give us a good start. Unfortunately Marlon [Samuels] got out off the first ball, but we bat deep.
"Credit must also go to Pakistan. Yasir [Shah] was very threatening off the rough."
