Joe Root hit a century as England set themselves up for a victory push on day three of the second Test against West Indies.
The 24-year-old hit 118 not out, his sixth Test century, achieving his hundred in just 125 balls as the tourists reached 373-6 in their first innings to lead their opponents by 74.
England also had other successes as Alastair Cook and Jonathan Trott shared the team's first century opening stand for more than two years.
They were well supported by Gary Ballance (77), who passed 50 for the eighth time in 10 Test matches, although Cook (76) was denied a first Test hundred since May 2013 by Shannon Gabriel.
