We report the discovery of three new transiting hot Jupiters by WASP-South together with the TRAPPIST photometer and the Euler/CORALIE spectrograph .

WASP-74b orbits a star of V = 9.7 , making it one of the brighter systems accessible to Southern telescopes .
It is a 0.95 M _ { Jup } planet with a moderately bloated radius of 1.5 R _ { Jup } in a 2-d orbit around a slightly evolved F9 star .

WASP-83b is a Saturn-mass planet at 0.3 M _ { Jup } with a radius of 1.0 R _ { Jup } .
It is in a 5-d orbit around a fainter ( V = 12.9 ) G8 star .

WASP-89b is a 6 M _ { Jup } planet in a 3-d orbit with an eccentricity of e = 0.2 .
It is thus similar to massive , eccentric planets such as XO-3b and HAT-P-2b , except that those planets orbit F stars whereas WASP-89 is a K star .
The V = 13.1 host star is magnetically active , showing a rotation period of 20.2 d , while star spots are visible in the transits .
There are indications that the planet ’ s orbit is aligned with the stellar spin .
WASP-89 is a good target for an extensive study of transits of star spots .
