Matthew Griffin (Sr., Londonderry, NH)
Event: 800m
Overview: The New Englander returns back to Chicago in a quest to win the 800m and produced another national banger. Last weekend at the adidas National Indoor Championship, Griffin placed fourth in the 1k with a personal best of 2:29.35. Before that, he ran the 600m in a US#2 1:20.32. However, his 800m is a misleading 1:55.07 from early February. There are indicators that say otherwise and if things hold true, we could witness something in the 1:52-1:53 low range.
