The Spaniard’s bag is packed with Callaway equipment.

• Callaway X Forged UT - FIRST LOOK!

At the long end of his bag he uses last year’s Epic Flash Sub Zero driver and two MAVRIK Sub Zero fairway woods.

The 27-year-old put a ball striking masterclass around the Fairmont course in St Andrews with a mix of his Callaway Apex Pro and Apex MB irons.

• Callaway Apex MB irons – FIRST LOOK!

He ranked first in Strokes Gained: Approach for the four rounds and found over 71% of greens in regulation.

Around the greens Otaegui puts his trust in two Callaway JAWS MD5 wedges and on the greens he wields an Odyssey Stroke Lab Black 10.

• CHROME SOFT vs CHROME SOFT X – How good are Callaway’s 2020 tour golf balls?

His work on the greens was key to the victory, averaging 10.25 1-putts per round and ranked seventh in Strokes Gained: Putting.
