Holland Reach 300

Holland have passed another milestone in the last session of play. With 12 overs still to play, they have just passed the 300 mark. Kenya still persisting with the spinners. I would have thought a quick burst from each of the strike bowlers would do the trick. I don't know the rules for the new ball, but I would have thought it would be available after 80 overs? Holland 6-301. van Troost on 21, Reekers on 2.
