Wiersma was born in Hilversum and played for amateur side Donar until 1954, when he was signed by PSV Eindhoven.

Besides football, Wiersma played a range of different sports at Donar, including baseball, basketball and table tennis.

His games at Donar were combined with his performances on the national Air Force football team (as part of his conscription).

His father and siblings already worked for the Nederlandsche Seintoestellen Fabriek (NSF), which was partially owned by Philips.

[6] Throughout his career, Wiersma faced a few problems with PSV: the club promised to financially support his engineering education, but failed to do so until he threatened to move to Feyenoord.

[2][5] Still, Wiersma remained at PSV for ten years and was captain of the 1963 squad that won the Eredivisie, his first and only trophy.

[6] He was present at PSV's first match in the European Cup in September 1955, when they faced Rapid Wien (and lost 6-2 on aggregate).

[8] After PSV appointed Bram Appel as the new coach, he announced a new focus on younger players and notified Wiersma that he was not needed anymore.

[2][7] While still playing for Donar in the third tier of the Dutch league system, Wiersma debuted in the Netherlands national team.

The Dutch team lost 3-2 and Wiersma was stretchered off the field: after a hard tackle by Robert Dienst, he landed on the running track and ended up with a bloody face and a concussion.

[5][11] His national team career ended after a row with coach Elek Schwartz, who benched Wiersma after a 4-1 loss against Denmark in 1962.

I could only manage so many years at this level because of my combativeness and because apparently, there are no better defenders around.”[7] After his retirement, Wiersma remained involved in sports.
