Alyssa Wiles was stabbed to death by her ex boyfriend Micheal Ray in June.
He pleaded guilty and was sentenced to life in prison without parole.
The Duncan Middle School baseball team is hosting the tournament in Wiles' memory.
Pool play continues tomorrow at 11:30 a.m. at Duncan Middle School and Duncan High School.
Games continue Saturday at 3:00, 5:15 and 7:30 p.m.
Admission is $5 per day or $10 for the entire tournament.
That money will establish a scholarship in Wiles' memory.
