San Diego Padres shortstop Fernando Tatis Jr. said he will not compete in next month's Home Run Derby, citing his shoulder and the team's postseason hopes.

Tatis, who entered Friday third in the majors with 22 homers, has been having trouble this season with his left shoulder, which caused him to land on the injured list at the start of the regular season.

Tatis said he hopes to participate in several derbies down the line.

"I'm 22, so I feel like there's gonna be a lot more chances for me to go to the Home Run Derby, and when I go over there I want to give a pretty good show," Tatis said.

The Padres began Friday 4.5 games back in the NL West.
