Striker Calum Dyson opened his goalscoring account for Plymouth Argyle in a 1-0 victory over Schermbeck 1-0 on Tuesday night.
The Pilgrims' squad are based in the Netherlands for a training camp this week, but crossed the border into Germany for their latest pre-season match.
Dyson had not got among the goals in any of Argyle's six previous warm-up matches.
However, he struck in the 83 minute of their match at the Volksbank Arena with a close range header.
SVS will be playing in Oberliga Westfalen, the fifth tier of German football, this season and they gave the Pilgrims a good work-out in sweltering conditions.
The temperature was in the lower 30 degrees centigrade, even in the early evening, which led to both sets of players having a drinks break in each half.
Argyle manager Derek Adams told Plymouth Live: "It was a competitive match. Ten of our players got 90 minutes, which was really good for us.
Schermbeck went close to taking the lead in the first half but Argyle's 18-year-old 'keeper Michael Cooper made a superb save.
Cooper was joined in the side by another first-year professional, midfielder Cameron Sangster.
There were few chances in the second half until Dyson came up with decisive goal.
A free-kick from Lionel Ainsworth was headed back across by centre-back Scott Wootton and Dyson applied the finishing touch.
Adams thought Schermbeck provided decent opposition for his side, who had all taken part in a training session with the rest of the Argyle squad in the morning.
He said: "It was extremely hot so we had two drinks breaks.
Adams reported there had been no injuries picked up from the match.
The other members of the squad will play in a behind-closed-doors against Dutch opposition on Wednesday.
No details about the opposition, the venue or the kick-off time are being announced.
Striker Ryan Taylor was named among the substitutes for the game against Schermbeck after recovering from an ankle injury.
Adams admitted there was a possibility that Taylor could feature in the behind-closed-doors match.
The Pilgrims will also play away to Dutch second side MVV Maastricht on Friday (8pm local time, 7pm UK).
