(Cricket is played in "overs" of six balls, each over bowled from opposite ends by different bowlers. In this case the bowler took a wicket (got the batsman out) on the last ball of an over, so there were six intervening balls from the other end by the other bowler before he bowled again, whereupon he got wickets on the next two balls.)
So it looks like they'll go to the fifth and last day of the match tomorrow with a chance of either team winning it, rather than drifting along to a draw.
Like baseball, cricket is a game where something nothing happens for a long time, followed by a bunch of frantic action all at once. And like baseball, it's a pretty good sport for listening on the radio.
