SAN ANTONIO, Texas — The opening half of the 2010 Valero Alamo Bowl couldn’t have gone worse for the Arizona Wildcats. They currently trail 23-7 at the break.

Oklahoma State University took advantage of big plays, including a 71-yard touchdown to receiver Justin Blackmon and a pick-six by safety Markelle Martin.

Martin made more of an impact on the Arizona sideline when he knocked running back Keola Antolin out of the game with what looks to be a concussion. Antolin has not returned to action since.

The game started rough for Arizona on its opening possession when William “”Bug”” Wright — back from his first action after a suspension — muffed a punt that set up quarterback Brandon Weeden and the OSU offense at its own 26-yard line.

Oklahoma State jumped out to a quick lead, putting up 14 points before the eight-minute mark in the first quarter.

Arizona responded with a touchdown when Arizona quarterback Nick Foles hit Juron Criner in the end zone for a 5-yard score.

But the half was marked by OSU capitalizing on the Wildcats’ mistakes. Arizona has three turnovers to go along with five penalties.

The second half will begin shortly. Stay with dailywildcat.com for updates. For live updates, follow @mike_schmitz or @nicoledimtsios on Twitter.
