Krenz set two world records in the discus and was considered a favorite for the 1932 Summer Olympics, but his career was cut short when he drowned at age 25.

[12] Krenz placed fourth in the Olympic shot put final, behind teammates Johnny Kuck and Herman Brix and Germany's Emil Hirschfeld.

[13] Krenz officially broke the discus world record in March 1929, adding more than five feet to Houser's mark with a throw of 49.90 m (163 ft 8+3⁄4 in).

[1] Two weeks later he won his third IC4A discus title, with a new meeting record of 49.01 m (160 ft 9+3⁄4 in), but Stanford lost the team championship to University of Southern California.

[19] At the NCAA Championships he was surprisingly beaten by Washington's Paul Jessup,[20] who went on to also win the national title that year, breaking Krenz's world record as he did so.
