The Musketeers have been recruiting Sumner for quite some time. The 6-foot-3 and 165 pound scoring combo guard picked up an offer from the Musketeers during the high school season, and after a strong showing during the EYBL in April, Sumner had the heat turned up by the Musketeers.
Last weekend Sumner made a visit to the school and he basically knew it was right for him, and after a week of debating between Xavier and Massachusetts the decision was made in favor of the Musketeers.
"Xavier has been on me the longest and they have made me a priority unlike other schools," said Sumner.
He continued, "The basketball program and the school itself fit me perfect and it's close to home. Also they do a real good job of developing their players."
Sumner is the second commitment for the Musketeers in the class of 2014. He joins four-star power forward Melvin Swift in the commitment column for the school who will play its first Big East season this year.
Currently Sumner is a three-star prospect and the No. 23 ranked shooting guard in the country.
