[2] He was then recruited by Coach Aldin Ayo to play for the UST Growling Tigers in Metro Manila's UAAP.
[4][5] After the tournament, Ateneo star player Thirdy Ravena called him a "threat to the whole league in the next coming years.
[12] In that game, he and Renzo Subido made back-to-back threes in the third quarter that extended the lead for UST, who eventually came out with the win and were on to the next phase.

[32] In Game 1 of the Finals, he had 13 points and seven rebounds in just under 20 minutes, as he injured his foot following a highlight putback jam in the third quarter.
He then went on to score eight of his 14 points in the fourth quarter to power the Knights to their 19th NCAA crown via a perfect 12–0 sweep of the season.
[39] He had originally planned to stay with Letran for his final year there, but his showing against the Korean national team made him change his mind.
[41] On October 3, 2022, Abando scored just two points off a highlight dunk before missing his next six shots in his KBL Cup debut.
He then dropped 20 points on seven of ten shooting and two blocks in a matchup against fellow Filipino import RJ Abarrientos and the Ulsan Hyundai Mobis Phoebus, which he won.
[52] Abando then won the 2023 EASL Champions Week pre-season tournament with Anyang, putting up 11 points and two rebounds in a 90–84 win.
[57] Game 4 saw him put up a team-high 22 points with four triples, five boards, three blocks, two assists, and one steal, against zero turnovers in over 35 minutes as a starter.
The following game, he went cold from the floor with only four points on 2-of-12 shooting, but made contributions on the defensive end with 10 rebounds and six blocks.
[60] In Game 7, he didn't score a single point, but he contributed on defense as his teammates stepped up to give Anyang its fourth KBL title.
[65] For the meantime he joined non-league Philippine team Strong Group Athletics (SGA) for the 2024 William Jones Cup in Taiwan.
[67] He received offers to play in South Korea, Japan, Dominican Republic and the ABA League but none of them were finalized.
[71] He originally was a reserve for the 2022 FIBA Asia Cup,[72] but after Dwight Ramos suffered from shin splints that forced him to drop out, he was included into the roster.
