Lipari won in 4:39.8 outkicking Cory McGee (4:41.0) and Sarah Brown (4:41.7) while McEntee won in 4:03.0 over Daniel Herrera (4:03.7).

Men's race has Lawi Lalang, last year's runner-up Daniel Herrara and Brandon Hudgins.

These are going to be two must-watch finals. Will Ben Blankenship's amazing 2015 continue or will he go home devasted thanks to Robby Andrews or Kyle Merber? The battle for women's spots #3 and #4 (thank you Ms. Simpson) will be incredibly intense on the women's side.

Sarah Brown won the 1500 in 4:07.67, while Sheila Reid was 6th (4:11.38). Anthony Romaniw beat Harun Abda in the 800 with 1:47.95, and back in 7th and 1:49.72 was Andrew Wheating. Ross Proudfoot won the 1500 (3:39.62) over Nate Brannen and Wallace Spearmon won the 200 in 20.77.

The final two sections of the men's 1500 and the men's and women's 5,000s were all cancelled due to a thunderstorm, which meant no races for Robby Andrews, Galen Rupp or Kara Goucher. Manzano won a slow 1500 in 3:38.96 over Wheating (3:39.56), while Rowbury (1500) and Symmonds (800) both had runners go down directly in front of them, messing up their races.

Mark Wetmore's two biggest stars will make their season debuts - Jenny Simpson (800) and Emma Coburn (1,500) - while Kara Goucher (5,000) will run her first track race since 2013 and Mary Cain will look to regain her "teen phenom" label.

Oh baby is this one loaded. Season debuts for Bernard Lagat, Emma Coburn and Jenny Simpson. A three-way slugfest for the 1000m AR between  Centrowitz, Sowinski and Loxsom. A world record attempt in the women's DMR. Other stars like Mary Cain, Nick Willis and Lawi Lalang. Saturday's meet in Boston is going to be good.

Merber left it late but swung wide on the final turn to beat David Torrence and get revenge on Garrett Heath,running 3:56.46 for the victory as Jordan McNamara was a non-factor. Mackey went wire-to-wire and ran away from Stephanie Brown and Morgan Uceny to win in 4:27.79.

Our preview of the women's action, which features a clash between teen phenoms Mary Cain and Ajee' Wilson in the 1,000, a women's 2,000 with Kim Conley, Shannon Rowbury, Morgan Uceny, Treniere Moser and others, and a women's two-mile where Jenny Simpson and Sally Kipyego renew their rivalry and try to hold off Ethiopia's Sentayehu Ejigu.
