Undefeated fighter highlights MMA card at Kezar Pavilion

Adam Piccolotti puts his undefeated record on the line Saturday during Dragon House 18, a mixed martial arts card at Kezar Pavilion.

After going 4-0 as an amateur, Piccolotti is 3-0 as a pro entering the 15-fight card that begins at 4 p.m. But he faces a tough foe in Tristan Arenal in the lightweight title bout. Arenal is 6-3 as a pro after a 4-0 amateur mark and has eight first-round stoppages in his career.

In the co-main event, the experienced Jaime Jara, 32, takes on older but less experienced Mauricio Alonso, 45, in a middleweight fight. Jara is 38-17-1, while Alonso is 9-5.

One other title is on the line. Josue Lugo (4-1-1) faces Derrick Williams (2-2) for the heavyweight championship. There will also be one bout featuring female fighters. Jaimee Nievera will make her pro debut against Jillian Lybarger (0-2).
