Pujols was named an All-Star reserve on Monday. This will be the his fourth time competing in the derby, however his first time since 2009. Pujols has never won the competition.
The 35-year-old Pujols is currently leading the American League with 25 home runs.
Last month, Pujols said he would take part in the 2015 Home Run Derby if he made the All-Star team and added he thinks it would be his last one.
On Monday, Washington Nationals rightfielder Bryce Harper, who also has hit 25 home runs, told reporters he will not participate in the Home Run Derby. Seattle Mariners outfielder Nelson Cruz also recently declined an invitation.
