Hint
Try re-writing each statement so they are all 'finished before'.
Answer
Blake won...
...then Dale, Alex, Chris, and Emery.
By placing the person who finished higher to the left we have:
1. Dale finished before Alex (Dale > Alex)
2. Emery finished after Blake (Blake > Emery)
3. Alex finished before Chris (Alex > Chris)
4. Emery finished after Dale (Dale > Emery)
5. Blake finished before Alex (Blake > Alex)
6. Dale finished after Blake (Blake > Dale)
7. Chris finished before Emery (Chris > Emery)
From 1 and 3:
Dale > Alex > Chris
Adding 7:
Dale > Alex > Chris > Emery
Adding 6:
Blake > Dale > Alex > Chris > Emery
Which is the final placing for all of the players, and can be double-checked with the remaining clues.
