And although Wednesday could have taken the lead when a mistake by AlexBaptiste allowed Lowe to venture clean through on goal, it was Phillips's namesake who made the breakthrough.
There was still time before the break though for the visitors to threaten with Marshall first palming away Alex Baptiste's header from 12 yards and later taking two attempts to prevent Keith Southern's effort.
The match could not have started much better for the Welsh side, who laid down an early marker of intent when Chopra got across AlexBaptiste to toe-poke a cross from Peter Whittingham that smashed against the crossbar after just four minutes.
