Former Oak Mountain High School star David Dahl’s first Major League home run since May 16, 2021, set the stage for history, and Ha-Seong Kim brought it home in the bottom of the ninth for the San Diego Padres on Monday night.

In San Diego’s 5-4 victory over the Arizona Diamondbacks, Dahl and Kim became the first players batting in the eighth and ninth slots, respectively, in the lineup to connect for game-tying and walk-off home runs back-to-back in MLB history.

With the Padres trailing 4-3, San Diego manager Bob Melvin sent the left-handed-hitting Dahl to the plate as a pinch-hitter for right fielder Jose Azocar to lead off the bottom of the ninth against right-handed reliever Scott McGough.

Dahl hit McGough’s second pitch — an 87-mph splitter — 398 feet over the fence in left-center at Petco Park for a game-tying homer.

The Padres’ second baseman, Kim followed with his first home run of the season to end the game.

“I’m kind of sorry for David that I took all the spotlight,” Kim said through an interpreter, “but he hit a great tying home run that was able to set me up for a great moment. Giving the team the win was the most important thing.”

The 10th player picked in the 2012 draft and a former National League all-star, Dahl spent last season in the minors with two organizations. But as a non-roster invitee, he earned a spot on San Diego’s regular-season roster in spring training.

“I’m so excited,” Dahl said in the locker room after Monday night’s game. “Just thankful for this opportunity and glad to put the team on the board right there. …

“It feels great. I’ve been watching from afar the last couple of years here, and it just looks so fun, and I’m so thankful to be a part of it now.”

Since being drafted by the Colorado Rockies, Dahl’s baseball career has been a series of comebacks, mainly because of injuries.

In 2013, Dahl’s second minor-league season amounted to 10 games because of a torn hamstring. In 2014, he hit .299 with 41 doubles, eight triples 14 home runs and 21 stolen bases at two minor-league stops.

While playing center field for the New Britain Rock Cats in the Double-A Eastern League, Dahl collided with second baseman Juan Ciriaco while trying to catch a short fly on May 28, 2015. He sustained a lacerated spleen, and the organ was removed. The next season, Dahl got called up to the big leagues after hitting .484 with five home runs in 16 games for the Triple-A Albuquerque Isotopes.

Dahl made his MLB debut on July 25, 2016, and ran off a 17-game hitting streak, tied for the longest in history from the start of a career. But his entire 2017 season was wiped out by a stress reaction in his rib cage.

In 2018, Dahl broke his right foot fouling off a pitch, and the injury kept him out of the Colorado lineup in June and July. He returned to hit six home runs in the final eight games of the regular season to help the Rockies reach the playoffs.

National League players selected Dahl as an outfield reserve for the MLB All-Star Game in 2019. Dahl singled and scored in his only at-bat in the annual Mid-Summer Classic. But less than a month later, he was out for the season because of a high ankle sprain sustained trying to make a catch in center field.

Dahl batted .302 with 15 home runs and a .524 slugging percentage in 100 games in 2019. But the Major Leagues’ truncated 2020 season was even more abbreviated for Dahl, who played in only 24 games because of back soreness and a shoulder injury that required surgery after the season.

The Rockies declined to offer Dahl a contract for the 2021 season, and he signed with the Texas Rangers. After hitting .210 with four home runs in 63 games for Texas – and missing more than a month for a rib injury sustained crashing into the outfield fence – Dahl played in 85 Triple-A games in the minor-league systems of Washington Nationals and Milwaukee Brewers in 2022.
