Astros' Peter Solomon: Demoted to taxi squad

Solomon was optioned to Houston's taxi squad on Monday, Julia Morales of AT&T SportsNet Southwest reports.

The right-hander allowed one run over four innings of long relief Sunday and has been removed from the big-league roster in favor of a fresh arm. However, Solomon will remain with the team on the taxi squad and could rejoin the active roster before the end of the season.
