Comptons done a good job there, exactly what was required given the conditions, hang in there, bat long and get a score on he board. 300+ will be a good score on this wicket and outfield.
Sometimes scores alone don't tell the story, a wicket thats doing a bit, rain interuptions breaking batsmans rythem and keeping bowlers fresh and a slow outfield. 179-4 is easily worth 240-4 on another day.
