Kießling continued to show consistently good form during the second half of the season and scored seven goals in the final six Bundesliga matches, including a brace against Hoffenheim on 20 April 2013 and game-winning goals against Werder Bremen on 27 April and Hannover 96 on 11 May. He was ultimately crowned the Bundesliga's highest scoring player for the 2012–13 season (having netted 25 goals in total, edging out Robert Lewandowski who finished with 24 goals). This personal record was secured with a goal on the final day of the Bundesliga season against Hamburg; scoring from a Sidney Sam pass in the final minute to secure a 1–0 win and third place in the Bundesliga.
