Waianae's Rachael Ostovich in the second UFC fight of her career, fell to Montana De La Rosa via submission on Friday at the TUF 27 Finale in Las Vegas.

After slipping out of a last-ditch submission from Ostovich in round 3, De La Rosa took Rachael's back delivering a flurry of punches.

Shortly after, Montana was able to sink in a rear-naked choke. The tap from Ostovich (4-4 MMA, 1-1 UFC) came at 4:21 of the final round.

De La Rosa (9-4 MMA, 2-0 UFC) picks up her second submission in the octagon after a successful UFC debut in December.

The women's flyweight bout wrapped up the preliminary card of the TUF 27 Finale.  It aired on FS1.
