It was a busy Friday night in the OHL, with both the East and West finals in play.

An overtime victory for Kitchener saw them take a big 1-0 series lead at the Aud, while Barrie relied on their big guns to even up the series against the Bulldogs.

Here's all the action from an entertaining night.

The anticipated battle between the top two teams in the West got underway in Kitchener, with 7,363 fans packing out the Aud on a Friday night.

They were treated to a busy first period, starting off fast with an Anthony Cristoforo goal just 47 seconds in quieting down the crowd.

Alexander Bilecki and Dylan Edwards put the hosts on top and some life back into the building, before Nathan Villeneuve quieted it back down at the end of the frame with the 2-2 equalizer.

It would be the Spits who would jump back to the lead fairly late in the second, as Philadelphia Flyers prospect Jack Nesbitt sniped one to put his team back in front.

But with a late power play, the Rangers would even it up through Jack Pridham, who banged home a rebound with 11 seconds to go in the second to level things up at three.

Pridham really needed a goal, as the 46-goal man in the regular season had 10 assists through nine playoff games, but had yet to find a scoring touch of his own.

The teams would come in and out of a defensive third period tied at three, and game one would require overtime.

There, it was the always-clutch Sam O'Reilly who scored in front just eight seconds into a four minute power play to send the Kitchener fans home happy.

That goal was O'Reilly's playoff-leading 11th goal, and the biggest one of his Rangers career to date.

Game two goes Sunday evening, with the Rangers looking to defend home ice while the Spitfires look to grab the split.
