The 38-year-old is a scout for the Tigers.
Williams was a teammate of Rowland-Smith in the 2004 Olympics for Australia.
Williams also knows RedHawks strength and conditioning coach Gary McCoy, another native of Australia.
BROWN MISSES GAME
Tacoma manager Daren Brown did not manage the Rainiers on Wednesday night and is not expected to be in the dugout Thursday night.
Brown is suffering from a sinus infection that kept him sidelined.
Brown was ejected in the seventh inning of Tuesday's RedHawks win, arguing balls and strikes after Josh Bard was ruled to have swung on a third strike to begin the inning.
Brown, who was born in Holdenville and played at Southeastern Oklahoma State, is back with Tacoma after taking over in Seattle on an interim basis for the final 50 games of last season after Don Wakamatsu was fired.
DELOME TO DL
Outfielder Collin DeLome was placed on the disabled list, retroactive to Tuesday, with a strained left biceps.
DeLome was one of the RedHawks hottest hitters but hadn't started since Friday in Omaha. He did pinch run and have on at-bat in Monday's game.
Pitcher David Carpenter was promoted from Double-A Corpus Christi before the game.
Drew Locke, who left Tuesday's game after hitting a double, did not play Wednesday.
