Baseball is different from cricket, you know.

Literal

Baseball [topic-は] cricket [with-とは] different [assertion-よ].

違う ('be different') takes its comparison target with と — 'different from X.' The は stacked on と gives 'different, as for (from) cricket.' よ adds emphatic confirmation. クリケット is an English loanword (katakana), reflecting the sport's minimal Japanese footprint.
