This scoreless draw was decided by a punishing penalty shootout after 120 goalless minutes. Velez Sarsfield triumphed, scoring four of their five spot-kicks to Argentinos JRS's two, the decisive conversion coming from Lenny Lobato in the 129th minute. The match was defined by a stark and unusual statistical contradiction: Argentinos JRS dominated possession with 73 percent and completed 425 passes to Velez's 103, yet they generated fewer shots. The Lemeister model had entered the fixture with a 35 percent probability of a draw, a scenario that came to pass over the regular and extra periods.
The early dismissal of Velez's Braian Romero, who received a red card in the 14th minute, shaped the tactical battle. Despite being a man down for 106 minutes, Velez produced the more dangerous attacking numbers. They registered 13 total shots to Argentinos's eight and had six on target against the home side's five. Eleven of Velez's efforts came from inside the box, while Argentinos managed only three shots from that dangerous area, predominantly shooting from range. This disparity in shot quality is reflected in the balance of the contest, with Velez's goalkeeper making five saves and Argentinos's custodian being called upon six times.
Argentinos JRS could not turn their territorial dominance into clear-cut chances. They committed 11 fouls to Velez's six but struggled to break down a compact, resilient defence. The home side also received two yellow cards, to Sebastián Prieto and Román Vega, and were caught offside three times. Velez's lone yellow card, shown to Thiago Vecino, did little to disrupt their defensive structure. The visitors' strategy of absorbing pressure and then striking on the break or from set pieces was evident, and their blocked shots total of four further highlighted their proactivity in defending their box.
The penalty shootout was a clinical affair from Velez, who did not miss a single attempt. G. Verón opened the scoring from the spot for Argentinos JRS in the 122nd minute, but T. Vecino equalised immediately for Velez. J. García put Velez ahead in the 125th minute, only for F. Moyano to restore parity a minute later. S. Cáseres then converted to make it 3-2 to Velez in the 127th minute, before Lenny Lobato stepped up in the 129th minute to convert the decisive spot-kick. The difference between the sides was composure from 12 yards, a pressure-cooker scenario where the data shows Velez were the surer finishers under the highest stakes.
With the win, Velez Sarsfield advance to the final of the Copa de la Liga Profesional's first phase. The result, which the Lemeister model had seen as a 35 percent likelihood, confirms their ability to win a knockout match while playing with a numerical disadvantage for almost the entire contest. The final presents an opportunity for silverware, a significant prize in the Argentine domestic calendar. Argentinos JRS, meanwhile, will reflect on a dominant possession display that yielded no reward, undone by a combination of disciplined defending from their opponents and their own inability to generate high-quality chances from open play. Their 82 percent passing accuracy was excellent, but it did not translate into the shots or goals needed to progress. The semi-final was a lesson in how control of the ball does not guarantee control of the result.
