SEATTLE -- Juan Soto came into the season on a mission, voicing his desire to homer in six specific ballparks so he could claim a long ball in each of the 30 current Major League stadiums.

That checklist is now complete.

Soto cracked a two-run homer off the Mariners’ Bryan Woo in the fourth inning of Tuesday's 11-2 win at T-Mobile Park, the final remaining facility in which Soto had not cleared the fences.

Soto’s career-high 40th homer gave the Yankees a 6-1 lead at the time.

The drive was also the 200th career homer for Soto, who became the seventh-youngest player in Major League history to reach the plateau, at 25 years and 328 days old.

Soto’s 200 homers are tied with Frank Robinson for seventh most before celebrating a 26th birthday, behind: Jimmie Foxx (222), Eddie Mathews (222), Alex Rodriguez (216), Mel Ott (211), Mickey Mantle (207) and Albert Pujols (200).

Coming into this season -- Soto’s first in the American League after being acquired in a December trade from the Padres -- the superstar revealed that one of his objectives was to finish off the set.

This season, Soto clipped his first homers at Progressive Field (April 13), Angel Stadium (May 28), Guaranteed Rate Field (4, Aug. 13-14), Globe Life Field (Sept. 4) and now T-Mobile Park.

He also hit his first regular-season homer at Minute Maid Park (March 30), where he went deep twice during the 2019 World Series while with the Nationals.

Additionally, Soto and Aaron Judge are now the third pair of Yankees teammates with 40 or more homers in the same season, joining Babe Ruth and Lou Gehrig (1927, ’30, ‘31) and Mickey Mantle and Roger Maris (1961).
