A mix of Test and ODI selections for West Indies. In recent memory...
1) Daren Ganga - Picked as a teenager for a 5-Test and 7-ODI tour of South Africa. What had he done? He scored one FC ton and apparently impressed someone, so in he went.
2) Xavier Marshall - Picked on the back of youth level runs and a good debut List-A season. But the worst bit was his continued selection despite looking woefully inadequated. I'm amazed he wasn't totally ruined by it.
3) Suruj Ragoonath - The worst specialist batsman to play for West Indies in the last decade. Picked because, IIRC, he scored a half-century against Australia in a warmup match. A classic "He hit big six!" selection.
4) Lincoln Roberts - A young man with a lot of potential, but picked on the basis of very limited domestic production and to play Australia. He registered a duck in his only Test innings. Amazed that he lasted 7 balls.
5) Dave Joseph - West Indies scraped the barrel for this one. Joseph was a mediocre domestic batsman, so he had no place being called up to play Australia. He played all 4 Tests of the 1999 series and was promptly discarded.
6) Dave Bernard Jr. - What did the selectors hope to achieve? He was so far short of Test class with both bat and ball and that much was obvious before he'd even received his cap.
7) Junior Murray - He had an immense season in 2001/02, so he was picked for the series against India, ahead of Ridley Jacobs. He scored 0, 0 and 1, then Jacobs returned. Ironically, Jacobs scored 0 in his first innings on return. He scored a ton an innings later.
8) Darryl Brown - Picked as an allrounder, despite being not just mediocre, but woeful with both bat and ball. An embarrassing selection.
9) Rawl Lewis - After proving to be one of the most substandard Test spinners in history, he was recalled for a tour of New Zealand, and then again for South Africa. Yes, Lewis improved as a bowler since his horrific debut, but there were many other better and younger spinners in WI at the time.
10) Rayad Emrit - Was never likely to be a success in ODI cricket. At best he's a first-class journeyman who can occasional contribute in List-A. Nowhere near international class.
11) Patterson Thompson - I don't need to explain this one. It must have been embarrassing for Ambrose, Walsh and Bishop to have to line up aside him.
Note also Lendl Simmons and Austin Richards.
