Swansea beat Yeovil 2-1 in their first pre-season game, Graham Potter's first in charge
Swansea City have lost both their Interwetten Cup matches, against Genoa and FC Magdeburg, on penalty shootouts.
Following a 1-1 draw against Serie A side Genoa, Kyle Naughton and Jordi Amat both missed penalties as Swansea lost the shootout 4-3.
It was a similar story against hosts Magdeburg later in the day as Graham Potter's side lost a shootout 4-2 after a goalless 60 minutes of play.
Both games were made up of 30-minute halves instead of a full 90 minutes.
Potter fielded entirely different sides for the two matches.
Ghanaian forward Andre Ayew featured against Magdeburg despite interest from Turkish side Besiktas.
There was also a start for Jefferson Montero, who has returned to Swansea after a season on loan at Ecuadorian club Emelec.
