Speedster Kemar Roach, who twisted an ankle earlier in the game and then sustained a blow to his hand while batting earlier in the day, did not bowl a single over while fellow pacers Fidel Edwards and Ravi Rampaul sent down just 10 overs between them.
The West Indies suffered a crushing 10-wicket defeat against England Lions here Sunday, just four days ahead of their clash with World No.1 England in the opening Test at Lord's.
Without the full services of their three-pronged pace attack, the West Indies struggled to make any inroads and the Lions easily wiped off the 197-run target set for victory, before tea on the final day of the four-day tour match at Wantage Road.
Rampaul left the field after bowling just four overs and even when he returned, was not used as a bowling option.
Edwards has struggled with injury in recent weeks and sat out the opening tour match against Sussex last weekend in Hove.
A West Indies team official, however, said all three players were expected to be fit for the Lord's Test.
With the Windies resorting to off-spinners Shane Shillingford and Marlon Samuels as their frontline attack and Darren Bravo as support with his unpractised medium pace, Joe Root grabbed the opportunity to stroke his second first class hundred - an unbeaten 115.
His partner Michael Carberry hit an unbeaten 72 as the Lions encountered little difficulty against the depleted Windies attack.
Earlier, West Indies were dismissed for 390 after resuming the day on 377 for eight.
