San Diego's Petco Park erupted Tuesday night as Luis Rengifo, a player discarded by the Milwaukee Brewers in late June, delivered a cathartic grand slam off Kyle Harrison in the second inning. The blast, which sailed into the left-field seats, gave the Padres a 5-0 lead and set the tone for an 11-2 rout that handed the Brewers—the team with the best record in baseball—their second consecutive loss in the series.

Rengifo's journey back to the majors began when the Brewers released him on June 23. Six days later, he signed a minor league deal with the Padres, and after a brief stint in the minors, he made his San Diego debut on July 10. Tuesday's grand slam, his third home run of the season, came with two outs in the second inning after Fernando Tatis Jr. battled Harrison to a full count. Tatis, who had initially been called out on strikes, challenged the call and won, turning a potential inning-ending strikeout into a walk. That set the stage for Rengifo, who jumped on a 1-0 fastball and sent it deep.

Tatis himself added to the night's fireworks in the fourth inning, launching an opposite-field home run to right. The solo shot was the 164th of his career, moving him past Nate Colbert for sole possession of second place on the Padres' all-time home run list. Only teammate Manny Machado, with 217, stands ahead of him. Tatis now has 12 homers this season, a modest total by his standards but a testament to his continued impact.

Campusano, the Padres' catcher, joined the long-ball parade in the fifth inning, crushing a two-run homer that extended the lead to 8-1. The Padres' offense pounded Harrison for eight runs (all earned) on 10 hits over just 4 2/3 innings, with all three home runs coming off the left-hander. Harrison, who entered the game with a 9-2 record, saw his ERA climb after a rough night.

On the mound, Walker Buehler turned in a solid performance, earning his seventh win of the season. He allowed one run on three hits over six innings, striking out five and walking two. The right-hander, who had struggled in his previous seven starts, looked more like the ace the Padres envisioned when they acquired him. Relievers Wandy Peralta and Robert Suarez combined to close out the final three innings, allowing just one more run.

The victory pulled the Padres into a three-way tie with the Philadelphia Phillies and Arizona Diamondbacks for the third National League wild-card spot. San Diego has now won four straight games and 14 of their last 18, a surge that has propelled them back into playoff contention. The team will go for a sweep on Wednesday, with trade deadline acquisition Robbie Ray (10-7, 3.24 ERA) facing Brewers right-hander Dustin May (6-7, 4.30 ERA).

For the Brewers, the loss was a rare stumble. They had won two of three against the Padres in Milwaukee in mid-May and entered the series with the best record in baseball. But Rengifo's revenge, Tatis's milestone, and a relentless Padres lineup proved too much. The series finale offers Milwaukee a chance to salvage a split, but the Padres' momentum suggests otherwise.
