Oklahoma Christian defeated Cedarville, Ohio, 5-2, in its second contest for its first win in the five-team pool. Earlier Thursday, OC fell to California Baptist, 11-4.
The Eagles are back above .500 on the year (26-25) and the win over Cedarville marked the first in a national tournament in 41 years.
To continue the run, the ninth-seeded Eagles must win Friday over fifth-seeded Southeastern (Fla.) and hope for a Cedarville victory over Mount Vernon Nazarene (Ohio). This would put OC at 2-2 in the pool and in second place.
The semifinals will be played Friday evening.
