HOUSTON -- The Mariners aren't ready to announce any decision yet on whether Felix Hernandez will make his next scheduled start Sunday, but general manager Jerry Dipoto did juggle the team's pitching staff heading into Thursday's opener of a four-game series, recalling right-handers Casey Lawrence and Nick Rumbelow from Triple-A Tacoma.
The Mariners placed recently acquired reliever Sam Tuivailala on the 10-day disabled list with a strained right Achilles tendon after the right-hander was hurt during a rundown play in Wednesday's loss to the Rangers. Chasen Bradford, another right-hander who threw 3 1/3 innings in relief over the previous two days, was optioned to Tacoma to open the other roster spot.
