McIlroy and Reed have a history of public animosity.

Surprisingly, McIlroy admitted to disliking Horschel even more, particularly during the 2007 Walker Cup.

[{"selector":"#anim-0893072d-2bb8-48f9-a7d1-49fc0abe7446","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-7fdb6d46-8d31-479b-af3c-988477e4da64","keyframes":{"transform":["translate3d(0px, 207.73949%, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}]

This revelation came during McIlroy's appearance on the "Subpar" podcast by GOLF.

[{"selector":"#anim-0a458c51-6ce6-422f-862c-5a5a3cde8ffc","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-88ee4899-6fd6-4145-8700-7653eda9e666","keyframes":{"transform":["translate3d(0px, 183.05205%, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}]

McIlroy and Horschel have since become close friends despite their past rivalry.

[{"selector":"#anim-fedead1a-e501-4a93-987b-a2d72a097066","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-dd273cc3-71e3-4a0e-ac28-8215aef0541d","keyframes":{"transform":["translate3d(0px, 231.81385%, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}]

The dislike for Horschel stemmed from his behavior towards the crowd during their matches.

[{"selector":"#anim-2cae6d2f-d7c6-409e-bef9-747081bbc6c0","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-e5f9ce6b-0043-41f6-afa7-318d67b5aa96","keyframes":{"transform":["translate3d(0px, 201.68354%, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}]

McIlroy felt a strong connection to the crowd and was offended by Horschel's actions.

[{"selector":"#anim-d81bdf1f-703f-4258-b087-6c342ebde86d","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-8c1a4870-91c8-44c0-9b52-c04660b07a29","keyframes":{"transform":["translate3d(0px, 188.11535%, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}]

Horschel had a better record against McIlroy during the 2007 Walker Cup.

Despite their past animosity, it appears that their relationship has improved over time.

[{"selector":"#anim-8533b852-b2c7-44fe-a9ed-4b5694630e2f","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-3ff179ac-4df5-45c2-aec2-72f7f100895c","keyframes":{"transform":["translate3d(0px, 239.13471%, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}]

The revelation sheds light on the complex dynamics and emotions in professional golf.
