Ruf went 2-for-4 with a solo home run, a triple, three RBI and a walk in Monday's win over the Rockies.
The 35-year-old took starter Kyle Freeland deep to open the game and then drove in teammates Steven Duggar and Kevin Gausman with a triple off of reliever Ben Bowden in the fifth inning. He has now launched a career-high 15 home runs this season in what has been his first full season in the majors since 2015.
