Seales has something to cheer about as he beats Jaiswal outside the off-stump after the left-hander played away from the body without any footwork.
However, the next ball is a bit too straight as the left-hander clips it through square leg for one.
Jaiswal and Sudharsan look totally settled at the wicket and the West Indies bowlers will need something extraordinary to dislodge them.
The duo pick two singles each off Chase's 12th over to keep the scoreboard moving along.
Seales mixing his length, bowling full as Sudharsan drives it straight back followed by a short but it slips down the leg side and is ignored.
Sudharsan clips the fourth ball off his pads for one and Jaiswal keeps out the last two balls.
