The Arizona Wildcats received their second commitment in three days this afternoon when offensive lineman Alex Kosinski gave his pledge to UA coaches.

Kosinski, listed at 6-feet-5-inches and 280 pounds, is from Redwood High School in Larkspur, Calif. He is unranked by the Scout.com recruiting service and Rivals.com 

He also had an offer from Air Force. 

Kosinski's commitment comes two days after Scottsdale Chaparral High School offensive tackle Keenan Walker committed to Arizona. 

Kosinski is the sixth member of the UA's 2015 recruiting class and third from California. Tight end Ricky McCoy (Fresno, Calif.) and Darick Holmes (Newbury Park, Calif.) are also from the Golden State.

"Two weeks ago I went there, and the Arizona trip was fun," Kosinski told Scout. "I got to talk with the coaches and they said they love my game. They like how I finish off blocks and that I play with a little bit of a nasty streak.

"They've got pretty much what I'm looking for."

Cal, Colorado, Arizona State and others had all expressed interest in Kosinski, but had yet to offer.
