(UPDATE) MANILA, Philippines: ONE enters the game practically seeking for survival while the other with a mission to flourish even more.Rivals Ateneo Blue Eagles and De La Salle Green Archers clash at 6 p.m. in a pivotal second round matchup in the penultimate day of the UAAP Season 86 men's basketball tournament elimination round at the Smart Araneta Coliseum today.Ateneo is the one avoiding to be pushed to the brink of elimination and secure its ticket to the Final Four by repeating on La Salle, which, on the other hand, is already semifinals-bound but looks to sustain its winning ways for a shot at a top two finish that merits a Final Four twice-to-beat incentive.Standing in fourth place with a 7-6 slate, the defending champs Blue Eagles need to win to punch their ticket to the next round and join the league-leading UP Fighting Maroons (11-2), second seed Green Archers (10-3), and third running NU Bulldogs (10-3) in the Final Four.A loss by Ateneo, however, would open the doors for the fifth seed Adamson Soaring Falcons, who will rise to 7-7 and force a playoff against the Blue Eagles for that last semis berth if they beat the UE Red Warriors tomorrow (Sunday, November 19).The Blue Eagles, who beat the Green Archers in the first round, 77-72, on October 4, enter this rivalry game with a three-game winning run, the latest being an 80-74 escape of the UE Red Warriors last Wednesday.Despite winning three straight games, all coming in the homestretch of eliminations, Ateneo head coach Tab Baldwin doesn't think that his team's peaking at the right time.'Hopefully, we're still growing, which is important. But I don't think that we will be peaking anytime soon. We certainly need some really good performances. But, you know, this team should be largely intact next year,' said Baldwin.'And consequently, we should say this, we should see the same group of players play much better basketball next year, then they're playing this year. But that doesn't solve anything for this year. So we have to, you know, get on the drawing board. And we have to look at how we're going to play well against La Salle and go out and do that.'On the other hand, coach Topex Robinson and the Green Archers aren't about avenging their first round loss to the Blue Eagles.Instead, they are just seeking to perpetuate what they've been doing right in a winning run that has stretched to seven games, the longest winning streak yet this season.'We try to take out that revenge vocabulary in our system and we just want to be the better team come Saturday. Whoever the team is we're gonna play, it just so happened to be Ateneo,' said Robinson.'It just so happened they're the last team that we're gonna play and the team that beat us in the first round. It shouldn't define how we're gonna approach this Saturday game. It should be just doing our best, outworking the other team.'La Salle is coming off an 80-70 triumph over the also-ran FEU Tamaraws last Wednesday that also put the Taft-based team on the cusp of a second round sweep, but more importantly, it inched them closer for that twice-to-beat edge.A victory over the Blue Eagles would enable the Green Archers to finish at 11-3, enough for a top two finish and get one of those two twice-to-beat incentives regardless of the UP-NU game result tomorrow.A loss to Ateneo by La Salle and a win by NU over UP, though, would drop the Green Archers to third place with a 10-4 slate and secure the Bulldogs a top two finish with an 11-3 record and one of those semis bonus slots. If both La Salle and NU lost their last respective games and drop to identical 10-4 slates, they will figure in a playoff for that No. 2 spot.In case of a three-way tie at 11-3, La Salle holds the superior quotient over UP and NU and thus would clinch the No. 1 spot and have the Fighting Maroons and the Bulldogs figure in a playoff for that No. 2 spot.
