[6] Placed on a line with Hall of Famer Syd Howe, Giesebrecht distinguished himself as a rookie centre for the Red Wings in February 1939 when he scored three goals in the first period in a 7–3 victory over the New York Americans.

Giesebrecht began the 1939–40 season with the Red Wings, but found himself sent down to their farm team—the IAHL's Indianapolis Capitals—after scoring only 4 goals and 7 assists in 30 games.

The 1941–42 season again found Giesebrecht splitting his time between the Red Wings and their farm team Indianapolis Capitals (in the newly renamed American Hockey League).

He spent the majority of the season in Detroit, netting 6 goals and 16 assists in 34 games, and seeing a 2-game call-up for the Stanley Cup finals against the Toronto Maple Leafs.

[9] Giesebrecht found the championship that had eluded him his entire professional career, however, with the Capitals, scoring 1 goal and 3 assists in 10 games to defeat the Hershey Bears and win the Calder Cup.

He turned down an offer from Jack Adams to return to the Red Wings at the end of the war, and instead worked at his family business and played senior hockey.
