Former Mariners forward Roy O'Donovan scored a first-half hat-trick in Newcastle Jets' 5-1 away win over the Mariners in Gosford on Saturday.
But opposing No.9 Asdrubal wasted no time endearing himself to the Mariners faithful, scoring inside the first five minutes.
The Spaniard had a couple of other chances and caused the Jets defence some problems and showed even at 173cm he could win the ball in the air.
Before his early goal, Asdrubal got a jarring welcome to the A-League, as he was on the end of a couple of heavy fouls.
He was playing his first major competition game since January and understandably had less impact later in the match and was substituted in the 77th minute.
"He's still probably not as match fit as what we'd have hoped," Mariners coach Paul Okon said.
"But he's coming from a period of time where he didn't play regular football.
"We're happy that he gets a goal.
"He was lively, he was busy, he's a threat.
"Once he gets that match fitness into his legs, we think that he's going to be a real threat."
Despite getting well beaten on the scoreboard, the Mariners still had 20 shots - eight more than the Jets.
