Montas will take the hill against Texas on Tuesday, Jane Lee of MLB.com reports.
As expected, Montas will be called up from Triple-A Nashville on Tuesday to make his ninth start of the season in the big leagues. Through 48.1 innings with Oakland, he's logged a 3.35 ERA, 1.39 WHIP and 30 strikeouts. He will likely remain with the club following this start and get the call for Sunday's matchup with Colorado at Coors Field.
