Lewis is delighted to see Blues reach the summit
Linfield Ladies grabbed the Big Two bragging rights with a 3-0 victory over Glentoran this week.
The triumph at Ulidia sees the Blues shoot to the top of the table following three successive league wins.
Linfield manager Phil Lewis was thrilled with his side's performance in the big derby.
"I am absolutely delighted with the performance and result," said Lewis.
"We played very well, we were maybe slow out of the blocks but we had a very young team out.
"It was a big opportunity for some of the younger players and they where fantastic.
"Coming into the game Glentoran were unbeaten, they had a more experienced team out and I expected a very tough game against them.
"The first 25 minutes proved to be that, it was a massive win."
Goals from Louise McDaniel, Casey Howe and Kelsey Burrows sunk the Glens.
"We are still unbeaten in the league and it's a big boost for the girls," added Lewis.
"Our goals were really well worked.
"The opening goal came from a corner, it was whipped in by Kirsty McGuinness and it fell for Louise McDaniel who hammered it into the roof of the net.
"The second goal was a quick move, Casey Howe scored her first senior goal for the club.
"She brought the ball under control and onto her left foot and fired into the corner.
"The third goal came in the second half from another set play.
"A quick free-kick involving Megan Bell and Rebecca McKenna allowed Cailtin McGuiness to cross for Kelsey Burrows who finished well."
While pleased to be top of the standings, Lewis says the hard work is only beginning.
"We moved top with the win but at this stage of the season I'm not looking at the table," he added.
"If you keep winning games, the table will take care of itself.
"It truly is a case of taking a game at a time and seeing where that takes us. Cliftonville next week will be a firm test."
After the game, Linfield star Megan Bell received the Ronnie Morrison sponsored Linfield player of the Match award from Neil Morrow.
The Blues are next in action on May 15 when Cliftonville are the visitors to New Midgley Park.
Elsewhere, Sion Swifts recorded a 2-0 win at home to previously undefeated Cliftonville which moved the Swifts into third position.
Two goals in the first half proved to be enough for the Sion victory.
The deadlock was broken in the sixth minute when Aimee Mackin scored from a Tyler Toland corner.
Sion got their second midway through the half when Tyler Toland fired home from a Ciara Grant free-kick.
In the other fixture, Comber Rec and Derry City played out a scoreless draw.
Both teams picked up their first point of the season and the point for Comber was their first in the top flight of women's football.
Shannon McCullough went close for the home side in the first half and Derry came closest to scoring in the 48th minute when they hit the post.
