Bryce Harper won't participate in the Home Run Derby this month despite being invited to the event for a second time.

One of the reasons Harper decided to pass is his father's recent surgery. Ron Harper pitched for Bryce Harper in the 2013 Home Run Derby, when he finished second to Yoenis Cespedes. Ron Harper had rotator cuff surgery after a snowboarding accident.

"Not having my dad throwing to me is a big issue for me," Harper said, adding that his father "throws strikes" and knows where his "sweet spot" is.
