Doubts with comparatives and superlatives sentence

[Cesar.roncallo]

I made this sentence for homework:

Boris spielt gern Golf mehr als Fussball. Tennis is das, was Boris am meisten gern spielt.

Is it correct? It sounds quite odd to me, how would they be? Thank a lot!!

They are both wrong. Comparatives and superlatives in german just inflect the verb.

Boris spielt lieber Golf als Fussball. (gern/gerne is one of the few adjectives with irregular forms).

Tennis ist das, was Boris am liebsten spielt.

thanks a lot!!!
