SAN DIEGO (Interstat) — Munetaka Murakami hit his majors-leading 13th home run of the season to highlight a six-run second inning, Colson Montgomery added his ninth home run, and the Chicago White Sox beat the San Diego Padres 8-2 on Friday night at PETCO Park for their fourth straight victory.

Murakami’s three-run shot broke a tie with Aaron Judge and Yordan Alvarez for the MLB lead. Montgomery’s blast in the fifth gave Chicago its 14th multi-homer game of the season and a 7-0 lead. Murakami and Montgomery homered in the same game for the seventh time this season, the most by any teammate duo in a team’s first 35 games of a season in MLB history, according to Elias and Sarah Langs.

The White Sox improved to 15-17, while the Padres fell to 19-12.

Rookie left-hander Noah Schultz turned in a dominant start for Chicago, allowing just two hits over six scoreless innings with two strikeouts and no walks. Schultz, now 2-1 on the season, retired the final 12 batters he faced after a shaky first inning in which he issued three walks but escaped unscathed.

Germán Márquez took the loss for San Diego, surrendering five hits and seven earned runs over five innings with two strikeouts and five walks. His record dropped to 3-2.

The White Sox jumped on Márquez early. After a quiet first inning that included a caught stealing of Murakami, Chicago erupted in the second. Montgomery led off with a walk, and Chase Meidroth doubled to put runners at second and third. Sam Antonacci singled to left, driving in Montgomery. Meidroth scored on a force out by Austin Hays. After a walk to Tristan Peters loaded the bases, Drew Romo walked to force in another run. Andrew Benintendi followed with a sacrifice fly to center, scoring Hays.

With two outs and runners at second and third, Murakami launched a 1-1 pitch from Márquez into the right-center field seats, giving the White Sox a 6-0 lead. It was Murakami’s third hit of the series and his second home run in as many games.

Chicago added another run in the fifth when Montgomery led off with a solo homer to right-center, his ninth of the season. The White Sox scored their final run in the eighth when Antonacci singled, moved to third on a single by Austin Hays and scored on a single by Tristan Peters.

San Diego’s only runs came in the bottom of the eighth against White Sox reliever Jordan Hicks. Bryce Johnson walked, and after a strikeout, Fernando Tatis Jr. singled to put runners at the corners. Miguel Andujar’s ground-ball single through the middle, deflected by second baseman Meidroth, scored Johnson. Manny Machado followed with a sharp single to left, scoring Tatis to make it 8-2. Hicks got Xander Bogaerts to ground into a force out to end the inning.

Schultz’s outing was his third consecutive quality start. He allowed only a single to Tatis in the third and a triple to Tatis in the sixth, but stranded both runners. Schultz faced 22 batters, throwing 69 pitches, 46 for strikes.

Wandy Peralta pitched two perfect innings of relief for San Diego, striking out two. Tyler Davis and Jordan Hicks each tossed a scoreless inning for Chicago, with Hicks surrendering two hits but limiting the damage. Ron Marinaccio allowed one earned run on three hits over two innings for the Padres.

Tatis finished 3-for-3 with a walk, a triple and a run scored. Antonacci had two hits and an RBI for Chicago. Benintendi drove in a run on a sacrifice fly.

The game took 2 hours, 42 minutes before a crowd of 43,638.

The White Sox will send right-hander Drew Thorpe to the mound Saturday against Padres right-hander Dylan Cease. Chicago then faces the Los Angeles Angels on Monday before returning home for a series against Seattle. San Diego opens a three-game set at San Francisco on Monday.
