If you prefer oval balls to round balls, you might want to check out the Sportpark Gehlsdorf. From time to time, the local rugby team, the Dierkower Elche, plays there.
Maybe quick comparison to American football —
In rugby, two teams try to place the oval-shaped ball behind the opposition team’s tryline. The ball can be only be passed backward or sideways by hand and can only be taken forwards by a moving player or a kick. The ball-carrier can be stopped by a tackle or by driving him into touch.
In the Dierkower Elche, all the players are amateurs (and the referees as well), so you might not see a game in the style of Wales or the All Blacks, but one thing is for sure: After the game, you will get an ice-cold beer and a sausage for a fair price and a chat with the players and trainers.
So check out the schedule:

Next date in Rostock is:
13.08.2011: 5th Hanse Masters
How to get to Sportpark Gehlsdorf: travel by tram to the Dierkower Kreuz or take the number 15 (during the week) or 14 (at weekends) bus; this will take you to “Pressentinstraße”, where you should get off. If the weather is nice, you could grab your bike and take a tour, it’s just 30 minutes by bike from the city center, and this alternative is more relaxing (in what sense?) than taking the public transport.
