About 3 1/2 months after committing to Houston, Pat Day made it official.

Chapel Hill's senior left-handed pitcher signed with the Cougars on Wednesday during a ceremony at Chapel Hill High School.

Day, who switched his commitment from Texas Tech to Houston on July 21, was 5-5 with a 2.24 earned run average and 101 strikeouts in 46 1/3 innings this past spring. He chose Houston over offers from Kansas State, Ohio, and Texas Tech.

Day recently competed in the Perfect Game WWBA World Championships in Florida. The showcase event features dozen of select teams from across the country competing before hundreds of MLB scouts and college coaches. He told ETSN.fm that he spoke with representatives from the Blue Jays, Rangers, Angels and Diamondbacks while in Florida.

Day has not ruled out the possibility of turning pro if whichever team selects him in June’s draft makes a big enough monetary offer.

“It’s early, but I’m projected between the fifth and eighth round,” Day told ETSN.fm two weeks ago. “The Blue Jays have shown a lot of interest lately. They’ve been contacting me a lot throughout the summer.”
