The Rangers are delaying starting pitcher Colby Lewis' return to the rotation by a few days, so the team realigned its rotation plans for a weekend series vs. Houston.
Yu Darvish will start the series opener Friday, and he will be followed by Tanner Scheppers Saturday and Martin Perez Sunday.
The delay in Lewis' return doesn't have to do with his surgically repaired hip. The Rangers are waiting to see if third baseman Adrian Beltre (quadriceps) will need a trip to the disabled list. If Beltre goes on the DL, then the team will have a roster spot for Lewis. If he doesn't, then the Rangers will have to make another move to get him on the roster.
Therefore, Lewis and Robbie Ross are expected to start the first two games of the Seattle series, which starts Monday. The alignment depends on when the Rangers decide to make a roster move.
