INVINCIBLE MELODY (4) is knocking on the door after a strong second over 7f at Wolverhampton, coming from well back. Finds ideal race. BLUE SEEKER (6) produced a solid third tackling the same trip last start. Could be competitive again. BLEWBURTON (2) attempts a much easier race and rates a key threat if rediscovering best form. ORCHARD (5) returns following a break. Not far off among similar company last time and may surprise.
