Hannover's miserable start to the season continued on Saturday as they were beaten 3-0 by Mainz, whose summer recruit Yoshinori Muto scored his first goals for the club.Muto beat the offside flag to put Mainz in front with his shot hitting the inside of the far post on its way past Ron-Robert Zieler in the 15th minute.The Japanese striker added a second with a close-range header after Hannover failed to clear their lines and Yunus Malli took advantage of a defensive mistake from Marcelo to make it three early in the second half.Mainz's second win in a row puts further pressure on Hannover boss Michael Frontzeck, who watched his side slide to their second successive defeat.ends
