Roof shots: Every homer hit to the warehouse roof at Petco Park

SAN DIEGO -- The Western Metal Supply Co. Building was constructed in downtown San Diego in 1909. It was declared a historic landmark in 1978, and it became a defining feature of Petco Park in 2004, when the Padres’ sparkling home ballpark opened.

The building graces the left-field corner of the playing field, with its southeastern edge essentially serving as the left-field foul pole.

• History of the Western Metal Supply Co. Building

In 22 seasons at Petco Park, countless right-handed hitters -- and a few lefties -- have homered off the structure and into one of the building’s three levels. But only a very select few have ever homered onto the roof.

Here’s the full list of home runs hit onto the roof of the Western Metal Supply Co. Building:

1. Sept. 28, 2016: Hunter Renfroe (off Dodgers right-hander José De León)
Playing in only his seventh game in the big leagues, Renfroe wasted no time putting his raw power on full display. De León threw an inside fastball, and Renfroe turned on it, launching a Statcast-projected 434-foot blast down the line -- 109 mph off the bat with a 32-degree launch angle.

That combination was enough for Renfroe to become the first player to homer to the Western Metal Building’s roof in a game (though a couple of righty sluggers had previously done so at that year’s Home Run Derby -- Giancarlo Stanton and Mark Trumbo).

2. July 24, 2017: Renfroe (off Mets right-hander Jacob deGrom)
For the first 12 seasons of the ballpark’s existence, no player had homered to the Western Metal roof. Then, Renfroe did it in consecutive seasons. To date, this blast qualifies as the most impressive of the bunch -- and not merely because, at a Statcast-projected 449 feet, it marks the longest roof shot in the ballpark’s history.

Remarkably, it came against deGrom amid his ascent to stardom. Renfroe turned on a hanging deGrom slider, and he sent it onto the roof in improbable line-drive fashion -- especially considering the height of the structure (80 feet tall, per the Padres’ media guide).

3. Aug. 27, 2020: Fernando Tatis Jr. (off Mariners right-hander Matt Magill)
Tatis became only the second player to visit the Western Metal roof, joining Renfroe, when he teed off on a curveball from Magill. It probably qualifies as the most majestic home run of the bunch -- a Statcast-projected 448 feet with a 31-degree launch angle.

The only downside: It came amid the pandemic-shortened 2020 season, with no fans on the roof to chase down the baseball.
