Root ton takes England to 290
Joe Root's hard-working hundred carried England to 290 for eight in their 50-over warm-up match against a Vice Chancellor's XI.
England appeared set at several stages for a bigger total at the Sir Vivian Richards Stadium in Antigua, and had a fine platform at 170 for three in the 30th over thanks to a half-century opening stand between Alex Hales and Luke Wright before Root (104no) and Ben Stokes (58) put on 71 for the third wicket.
But three wickets for the addition of only 23, two lbw to young leg-spinner Akeem Dewar, halted the mid-innings progress.
Hales and Wright each had a chance in the absence of rested one-day international captain Alastair Cook and Ian Bell to make a case as openers in this format.
In a match also notable as England's first since the controversial axing of record runscorer Kevin Pietersen from all future plans, the tourists were put in on a sunny morning but after overnight rain.
Wright appeared marginally the more assured of the opening pair until he lost a little patience against left-armer Raymon Reifer's line wide outside off-stump and smeared a catch to deep cover.
Then 17-year-old seamer Alzarri Joseph, called into this match from outside the hosts' initial squad, had Hales mis-pulling to present him with a simple catch almost in the batting crease in his follow-through.
Stokes and Root soon looked in control, however, the former using the cross-wind to hit Dewar for back-to-back leg-side sixes in his first over.
He clubbed another in Dewar's next, just clearing with a pull off the bottom of the bat, to bring up his 50 in 59 balls.
But the left-hander mistimed another attempted big hit at the returning Miguel Cummins, and was caught at mid off.
Eoin Morgan's stay was short and fretful before he missed a reverse-sweep against Dewar (three for 67), who switched ends to significant effect and would also deceive Jos Buttler - misreading the leg-spinner's variations and shouldering arms to a ball that appeared to be going on to hit middle and off.
Two of England's most destructive batsmen had gone cheaply, and Root and Ravi Bopara therefore had to chip and scurry their way through a powerplay which yielded 24 runs and the Essex all-rounder's wicket when he poked a low and wide full toss from Reifer straight to cover.
Root's all-Yorkshire stand of 62 with Tim Bresnan ensured a competitive total nonetheless, and he completed his 103-ball hundred in the final over with a reverse-flick off Joseph for his ninth boundary.
