Oklahoma entered the postseason with plenty of momentum, but dropped its regional opener in Charlottesville on Saturday to Appalachian State, 5-4:

How the game was lost: After failing to get a hit through the first six innings, the Sooners brought the winning run to the plate in the bottom of the night inning, but came up short in trying to rally past the Mountaineers.

Player of the game: Appalachian State starter Ryan Arrowood threw a gem, keeping the Sooners hitless for six innings. Arrowood went 7 2/3 innings, allowing one run on two hits while striking out nine. Arrowood moved to 11-0 on the season.

Stat of the game: Left-hander Jordan John worked into the ninth for the Sooners but made two of OU’s four errors. The Mountaineers scored runs off both.

Unsung heroes: The last three hitters in the Mountaineers' lineup – Trey Holmes, Preston Troutman and Noah Holmes (Trey’s brother) – accounted for seven of Appalachian State’s 10 hits.

What it means: It’s hard to beat anybody collecting only two hits while committing four errors. The Sooners are one game away from having their season ended. They’ll try to keep it alive at 10 a.m. Sunday against Army in an elimination game.
