The Tigers would finish with a 2–1 record in the Final Four to set up a rematch with the Blue Eagles in the Finals, where the Tigers exacted their revenge against the Eagles as they were crowned the National Champions after winning the title in a tightly contested three game series.

However, in their first round encounter against the NU Bulldogs, he suffered from a shoulder injury after he got hit by Bulldogs forward Jeoffrey Javillonar.[12] Teng would miss five games from the injury as the Tigers struggled in his absence. Teng returned to the lineup in the second round encounter with the Bulldogs, however he re-injured himself, this time on his right hamstring.[13] Teng would make a quick recovery, and then in their battle with the Ateneo Blue Eagles for the last slot in the Final Four, he would hit five clutch free throws as the Tigers ended Ateneo's five year title run with an 82–74 victory that booked them a ticket to the Final Four.[14] The Tigers would later stun the top seeded Bulldogs as they won two straight games to return to the UAAP Finals for the second straight season. The Tigers would battle the De La Salle Green Archers in the Finals in which Jeric battled his younger brother Jeron for the championship. He played brilliantly in the series against the Archers as he led the Tigers in scoring in the three game series.
