Second-round pick Adam Erne enjoyed a strong NHL preseason debut Wednesday scoring twice in Tampa Bay’s 4-3 shootout victory against St. Louis in front of 6162 fans at Amway Center in the preseason opener for the Lightning.

Erne the 33rd overall pick in the June draft redirected a Mark Barberio wrist shot with 1:14 left in the second period for a power-play goal while he was all alone in front to receive a pass from Cedric Paquette for a second power-play goal 1:31 into the third period. Erne also notched the shootout-clinching goal.

“I thought I played well and it’s not all about the goals I thought our line played really well defensively’’ Erne said. “I get two goals but the first one Barberio is a great shot and the second one was an unbelievable pass from (Paquette) so without that there is no chance.’’

Tom Pyatt had the tying goal 9:11 into the third period while J.T. Brown added a pair of assists. Valtteri Filppula added an assist and a shootout goal.

Dmitrij Jaskin scored a pair of goals for the Blues while Jaden Schwartz also scored as St. Louis jumped out to a 3-0 lead.

It wasn’t all positive for Erne who delivered a blow to the head of Vladimir Sobotka in the first period that drew a penalty and could warrant review by the league. St. Louis coach Ken Hitchcock said it should result in a suspension.

“I was facing one way then I turned the other way and he was kind of right there and I wanted to hit him I didn’t think I was going to hit his head I didn’t mean to and I apologize’’ Erne said. “It was not intentional. ... It was my fault but I didn’t intend to do that.’’

As planned Cedrick Desjardins left after playing 31:51 allowing two goals on 14 shots. Kristern Gudlevskis received his first NHL action in relief allowing one goal on 14 shots before stopping both St. Louis attempts in the shootout.

After a slow start — Tampa Bay was outshot 14-2 at one point in the second period — the Lightning started to turn things around as the shots ended 28-27 for St. Louis.

“I really enjoyed the way they played’’ Lightning coach Jon Cooper said. “You are looking for (them to) compete ... and the guys hung in there. They probably had every reason to see the score was 3-0 and hang their head but they didn’t and that’s what we are looking for in the guys. So if they are going to keep giving efforts like this ... it’s continuing to make the decisions tough for us.’’
