Whanganui were only able to take one reserve to Palmerston North for the match, but had matters well in hand leading 3-0 at halftime.
"While it's nice to have extras and a few for the bench, sometimes it's easier with just a couple of subs," Baylis said.
The home side got a reply goal five minutes after the resumption, before Whanganui returned fire for 4-1 and then the two teams traded goals late in the game.
Baylis said Massey were a young team, who could not take advantage of all of their opportunities.
Whanganu's goal scorers were Charlotte Baker, Kirsty Parsons, Jan Dixon, Lucy Skedgwell and Robbie Matthews.
Whanganui will travel again this Saturday to take on College B, who were on the bye at the weekend.
Baylis said College B should have a stronger team than the side Whanganui beat 2-1 on April 28, while they will have to rejig the lineup again with a couple of players away at Under 18 tournaments.
"It is what it is, we go with it."
In the Manawatu Premier Men's draw, Tech College Old Boys had the bye on the weekend.
They will resume their campaign against High School Hockey Club A at the Twin Turfs on Saturday afternoon.
