"She is that defender that you are 100 percent okay with her having the ball and can take it over and go to goal if she needs to," Bailey said.
Meanwhile, the offense was methodically stretching the lead, while running through midfielders Weedon, Marshall, Marion and Sophi Wrisk.
Weedon and Wrisk will play at the University of Maryland in three years and Marshall will play at Iona University next year.
"All four of them work well together and they are able to balance off of each other and they rotate — who is that aggressive middie to put the pressure on defensively and who is going to take it 1 v 1 — they do a very good job of working with each other," Bailey said.
Catonsville, which won 10 of 16 draws with Marshall leading the charge, led 5-2 at halftime on goals by Marshall and Weedon.
The Sailors out-shot the Comets, 26-16, but only got five past Weedon.
"Me personally, I warmed up and did whatever I could to get pumped for this game and I had to go in with the right mindset," Amber Weedon said. "I think I was seeing the ball very well and I'm an active goalie and I like to come out and intercept."
After Wrisk made it 8-2 on a free-position goal, the Sailors finally broke their scoring drought on a goal by Lindsay Kelly, but they would get no closer than within four goals the rest of the way.
"I'm not taking anything away from them, they just took it to us and their goalie played a good game," Mount de Sales coach Eric Pfeiler said.
But, the coach was disappointed in his squad that has seven losses and is 2-5 in Interscholastic Athletic Association of Maryland A Conference play.
"We constantly shoot ourselves in the foot every week by not executing, catching and throwing or making the right pass," Pfeiler said. "We get our teeth kicked in every week by all these teams."
Bailey was happy to see her team respond positively after they lost to Hereford, 19-9, and squeaked past Loch Raven, 12-10, last week.
"We worked on having that patience and not forcing it and not rushing it and taking our time and that's how they play and we were able to work it to our advantage," Bailey said. "We were sliding, we were talking and we really did pressure when we needed to."
It's the second victory over a private school for the Comets this season as they also defeated Garrison Forest.
"This is a really good win for us as a program," Bailey said. "I think it will help us in the long run."
