CLEVELAND — The San Diego Padres put on a power display at Progressive Field on Sunday, slugging four home runs to back a strong start from right-hander Casey Mize and secure a 5-0 shutout of the Cleveland Guardians. The win gave the Padres a series victory, taking two of three in the weekend matchup, and further cemented their status as the hottest team in baseball since late July.

Luis Rengifo and Gavin Sheets ignited the offense with back-to-back homers in the second inning off Cleveland starter Tanner Bibee. After Bibee had retired the first five batters he faced, Rengifo drove an elevated sinker over the center-field wall. Five pitches later, Sheets punished a changeup, sending it just over the right-field fence. It marked the first time the Padres had hit consecutive home runs since last April, a spark that proved decisive.

Casey Mize, who came to San Diego from the Detroit Tigers at the trade deadline, delivered his strongest outing in a Padres uniform. Over six innings, he scattered three hits, walked none, and struck out five, mixing his splitter and cutter effectively to keep Guardians hitters off balance. The outing lowered his ERA to 5.09 and gave him his first win since joining the Padres, improving his record to 5-7 on the season.

Cleveland’s best chance to score came early. José Ramírez, who finished with two hits, singled in the first and again in the third, but each time Mize worked out of trouble. The Guardians managed only three hits total, none after the fourth inning, as San Diego’s bullpen closed the door with three scoreless frames.

Defensive highlights came from rookie Jase Bowen, who entered as a defensive replacement in the sixth inning. He made a pair of diving catches, robbing Angel Martínez and Nathaniel Lowe of extra-base hits in the sixth and seventh. Bowen then extended the Padres’ lead to 4-0 in the eighth with a solo home run to right field, his third of the season. Jake Cronenworth added a solo shot to right-center in the ninth, capping the scoring.

Tanner Bibee (4-13) took the loss, allowing three runs on six hits over six innings. He struck out six but struggled with location at critical moments, especially on the back-to-back homers. The Guardians’ offense has sputtered recently, with the team losing five straight series and going 4-11 since July 31.

Sunday’s game began after a 3-hour, 11-minute rain delay, but the weather did not cool off the Padres’ bats. San Diego has now hit at least four home runs in a game six times this season, a testament to their power depth. The team has gone 17-5 since July 24, the best record in the major leagues over that span, and is 6-0-1 in their last seven series.

Looking ahead, the Padres open a three-game series Monday night at the New York Mets, with right-hander Walker Buehler (7-5, 4.88 ERA) taking the mound. The Guardians will host the San Francisco Giants on Tuesday, starting left-hander Foster Griffin (13-4, 3.25 ERA), who will make his third start for Cleveland.
