I don't write much about grammar and punctuation on this blog, partly because they're not really my forte (too many commas, too many dashes). However, there is one mistake that I'm seeing more and more that is worth mentioning. Here's an example from an article by Chris Jones, The Evening Standard's tennis correspondent:
"Having lost the set to the world No. 57, the crowd witnessed a rare example of the Spaniard's temper as he thumped his fist into the strings of his racket."
This suggests that it was the crowd that had lost the set to the world No. 57--an amusing image but not what Chris Jones intended. It was actually Rafael Nadal who had just lost the set. One correct version would have been:
"Having lost the set to the world No. 57, Nadal gave the crowd a rare example of his anger, thumping his fist into the strings of his racket."
Editors, other than the sports editor at the Evening Standard, tend to notice such things and it doesn't reflect well on the writer.
