Zed Key and Javon Bennett each had 15 points and led a second-half charge that helped host Dayton erase a 13-point deficit and beat No. 6 Marquette 71-63 on Saturday night.Key had four dunks in the second half for the Flyers (9-2), who shot 55.6 percent from the field following intermission after making just 36 percent of their first-half shots to trail 36-26 at halftime. Enoch Cheeks added 14 points for Dayton, which held the Golden Eagles (9-2) to 35.7 percent shooting overall after the break and owned a 21-10 advantage in second-chance points for the game.Chase Ross had 19 points and star Kam Jones added 18 for Marquette, which was the highest-ranked team to visit Dayton since Pittsburgh, also ranked No. 6 at the time, lost there in December 2007.Dayton trailed 39-26 after Jones opened the second half with a 3-pointer. However, that bucket apparently woke up the Flyers, who then used a 7-0 spurt — part of a larger 14-2 run — to get back into the game. Bennett headlined the charge with a pair of triples.The hosts trailed 53-49 before Malachi Smith (11 assists) and Bennett made layups to tie the game with 7:43 left. A layup and a dunk from Key followed to make it a four-point lead for Dayton, which never trailed again.
