Cox matched a career best with seven innings of work, allowing just two hits as the Bulldogs knocked off Samford 8-1 in the final game of the Diamond Classic presented by Polk's Meat Products.
"Will had good location and movement," MSU head coach John Cohen said. "He has a chance to be a really solid pitcher for us. He pitched well today against a very good offensive team in Samford. I liked what we saw on the mound throughout the weekend."
MSU won all four games it played in its own invitational tournament, including beating Samford twice. The Diamond Dawgs' perfect 9-0 start matches the 2006 squad, which won its first 18 games of the season. Through nine games, MSU has allowed 48 hits and 11 earned runs, while posting a team earned run average of 1.22.
"We have several guys we trust on the mound in certain situations," Cohen said. "Offensively, we had some mistakes, such as not getting a squeeze down. In all, we did a good job of hitting and had some key hits."
The Bulldogs broke a scoreless tie with three runs in the fourth inning. Detz had an RBI-single and Nick Ammirati had an RBI-double in that inning. The lead grew to 7-0 an inning later with a two-run double by Detz and two-run single by Derrick Armstrong.
Samford (5-4) finally touched Cox for a solo home run by Phillip Ervin in the seventh inning.
In Sunday's tournament opener, Samford scored three times in the ninth inning to defeat Purdue, 6-3.
MSU hosts Rhode Island at 4 p.m. Tuesday and Wednesday at Dudy Noble Field.
