Athlete Quotes

Shelby Ashe (gold, women's hammer) -- It was really weird. I thought I would be ok after the weather break, because every other big meet when it rained I was ok. I didn't get as big a throw as I wanted, but I will take this one. I will be taking a year off before I attend college so I can train with coach Mike Judge in Georgia.

Karen Henning (bronze, women's hammer) -- I just try not to think about it when weather affects the competition. It is Florida, it rains. I just tried to relax more on my later throws, loosen up my shoulders and let it happen. Now I get to have my summer vacation!

Morgann LeLeux (gold, women's pole vault) -- I broke a pole midway through the competition, at 4.05 I think, and the next pole up for me was a 14 170, which was just a bit too big today. I still have some more work to do. The headwinds were really tough and truthfully, I am just happy I won this.

Sandi Morris (silver, women's pole vault) -- Warmups felt great, I was clearing 14-0 on the bungee, and I only took about four warmup jumps. When we came back out after the rain delay it wasn't so good. The headwind was bad, but I made my opening height on my first attempt, which is always nice.It was so hot out there, and that got to me a bit later in the competition. I am very happy with my finish, though.

Trinity WIlson (gold, women's 100H) -- Winning the second part of the World Youth/Pan Am double is an extremely good feeling! I just didn't know how this would turn out since we didn't run prelims. My start was good and I stayed with everyone until hurdles 4, 5 and 6, where I started pressing and moved ahead. Technically this felt very good, but France was a little better.

Gabe Hull (silver, men's discus) -- At the beginning I was just thinking I would settle for whatever I could get, but then I thought that I had done well before so I could do well again. I almost reproduced the good things I had done before, so it ended up well and I had a good last attempt.

Diamond Dixon (silver, women's 400) -- I was really thinking about getting out fast, and I think maybe I went out a bit too quick on the first 200. I felt tired at 250 and didn't have as much strength over the last stretch as usual. It is tough to stay motivated and keep focus over a long college season, but you have to do that at this level.

Josh Mance (gold, men's 400) -- After being delayed so much before we got to run, I knew it was going to be really tough to run a very fast time. I just wanted to win at that point. This has been a really good freshman year for me, going to NCAA's and setting the freshman record.

Marvin Bracy (gold, men's 100) -- It feels great to be here at home and have my family and friends here to watch and then run fast and win. I didn't run real hard in the prelims. My hamstring was tight after relay practice Wednesday and the Team USA medical staff did a good job treating me. I know I can run under 10 in the future. Recruiting is out of the way (he committed to Florida State) and now I will focus on football next.

Keenan Brock (silver, men's 100) -- The false start messed up my concentration a bit and I held myself on the second start. I closed really well and felt great today. It is good to be home and run well.

JJ Juilfs (silver, men's pole vault) -- Yes, the weather affected me negatively. I did the best I could to adapt. I came to win, but I am thankful to be here. I had a lot of misses along the way, and the headwind was tough to deal with.
