What's the meaning of 'the underdog' in 'This outfit would be the underdog to a stiff breeze'

I have seen the sentence 'This outfit would be the underdog to a stiff breeze.' in a quote of the newspaper 'TIMES'.

I was looking for 'breeze' in the collins online dictionary and this phrase appears as an example, but without context.

If you look 'underdog' in the dictionary, you get: 'The underdog in a competition or situation is the person who seems least likely to succeed or win'. But I don't know how to apply this definition to the clothes. I can't understand what's the meaning of 'the underdog' in the sentence.

Solution 1:

Here is extended context from Geoff Shackleford, quoting Sports Illustrated contributor Rick Reilly:

This outfit would be the underdog to a stiff breeze. Or do Brett Wetterich, Zach Johnson, J.J. Henry and Vaughn Taylor make your timbers shiver? It sounds like somebody's Webelos troop. None of those four have ever played in a Ryder Cup before. Three of them missed the cut at last week's PGA, and Henry finished 41st.

An underdog is one who is not favored to win in a contest - Merriam-Webster calls them a "predicted loser." The Ryder Cup is in golf. So the writer is saying - rather colorfully - that a stiff breeze (a wind that is a bit more than mild) would outcompete these professional golfers. It's an exaggeration, like a pro soccer team being underdogs to an age-10 team.
