Experienced Pitching Could Lead Old Tappan’s 2026 Championship Push

Mar 10, 2026

Old Tappan High School enters the 2026 baseball season with a large group of returning contributors after finishing 18 to 8 last spring and going 8 to 2 in the Big North National. Many of the players who produced last season now return with another year of experience after moving up one grade. Several of the Golden Knights’ top offensive players return to lead the lineup. Now senior Max Garcia delivered one of the strongest offensive seasons on the team last year. Garcia hit .442 with 19 hits and 16 runs scored while driving in eight runs. He added eight doubles and two triples and finished with a .721 slugging percentage. Senior Selden Kolkebeck also returns after a major two way season. At the plate Kolkebeck hit .444 with 20 hits, 15 runs, and 10 RBI. Senior catcher Anthony Onnembo drove in a team high 23 runs while hitting .391 with 18 hits. His extra base power included three doubles, two triples, and two home runs. Senior AJ Aiello added power and production in the middle of the order. Aiello hit .350 with 14 hits and 18 RBI while recording two doubles, two triples, and two home runs. Senior Joey Crescitelli returns after hitting .304 with seven hits and six runs scored while adding speed on the bases. Several younger players also return with valuable experience. Junior Isaiah Rodriguez hit .400 with six hits and eight RBI last season. Junior infielder Caden Yoon added nine hits, seven runs scored, and five stolen bases while batting .360. While the offense returns strong production, the pitching staff could be the difference that pushes Old Tappan toward a championship run. Senior Selden Kolkebeck leads the rotation after posting a dominant 1.52 ERA across 60 innings last season. Kolkebeck struck out 78 batters while allowing only 13 earned runs. Junior David Brennan also returns after a strong sophomore year on the mound. Brennan recorded a 2.42 ERA across 43.1 innings and struck out 34 hitters. Together the staff finished last season with a 1.76 team ERA and 161 strikeouts across 163 innings. With one of the most experienced pitching groups returning in the conference, Old Tappan High School Baseball  has the type of depth on the mound that often decides championships. If the Golden Knights continue to control games with their pitching staff, the foundation exists for Old Tappan to make a serious run at a title in 2026.
