Diaz is a 6-foot-11, 220-pounder out of Miami's Hialeah-Miami Lakes, while Gipson is a 6-7, 245-pounder from Cedar Hill, Texas.
"As we were preparing for this year's recruiting class, we wanted to build depth on our frontline," said Martin. "We centered our focus on two frontline guys and we got exactly the two players we wanted in Adrian and Thomas. They both bring size and athleticism, but they are different players.
"Thomas is more of a big wide-body presence at the rim. He's a big, strong young man, who once he gets in our weight program will continue to evolve," scouted Martin.
"In Adrian, we have a 6-foot-11 runner who has a high skill level. Just like Thomas, he is a high level competitor who fits who we are at K-State."
Diaz is the third member of his family to play collegiate basketball as his brothers, Eric played at Eckerd College, and Andres is currently at North Florida.
Rated as the 13th-best prospect in the state of Texas by TexasHoops.com, Gipson led the team in scoring last year with a 16-point average, plus secured 7.2 rebounds per game.
His prep team ended up 28-4 overall and was ranked as high as No. 6 in the TABC (Texas Association of Basketball Coaches) Class 5A state poll. Gipson was a TABC first team Class 5A All-State selection and was co-MVP of District 7-5A.
He helped Cedar Hill to the 2009 Class 5A state final as a sophomore where he averaged 12.5 points and 8.5 rebounds per game. He was named first team All-Area by the Dallas Morning News and was the District 7-5A Sophomore of the Year.
