The 26-year-old right-hander was recalled from Triple-A Indianapolis earlier Sunday. Left-hander Enny Romero was designated for assignment to make room on the 25-man roster.
Pittsburgh selected Kingham in the fourth round of the 2010 draft out of Sierra Vista High School in Las Vegas. He underwent Tommy John surgery in May 2015, causing him to miss most of the 2015 and 2016 seasons.
In four starts with Indianapolis this season, Kingham was 2-1 with a 1.59 ERA.
