Montgomery will start Sunday's game against the Royals, Greg Johns of MLB.com reports.

EDGE Analysis

Taijuan Walker landed on the disabled list Wednesday, leaving a spot in the rotation open for Sunday's game heading into the All-Star break. Montgomery, who hasn't started a game this season but does have starting experience, will get the nod in Walker's place Sunday. Montgomery was able to go 4.0 innings in relief of Walker, so it'd be realistic to expect him pitching roughly the same amount of innings Sunday and making it a "bullpen game."
