We report the discovery of three new transiting hot Jupiters by WASP-Southtogether with the TRAPPIST photometer and the Euler/CORALIE spectrograph.  WASP-74b orbits a star of V = 9.7, making it one of the brighter systemsaccessible to Southern telescopes. It is a 0.95 M_Jup planet with a moderatelybloated 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. Itis 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 theplanet's orbit is aligned with the stellar spin. WASP-89 is a good target foran extensive study of transits of star spots.
