Anderson will start Sunday against the Padres.
Anderson, who was called up to replace Jake McGee (knee) on the roster Saturday, will get the nod over Eddie Butler in the series finale against San Diego. He will be making his major league debut a little more than five years after being drafted with the 20th overall pick out of the University of Oregon. Although Anderson has given up just one homer in 30.2 innings in the minors this year, he's had some issues with walks and the downside in any Coors Field start is significant.
