Smoak, who had started as the cleanup hitter 21 times this season, was dropped from fourth to seventh in the lineup.
And he's likely to stay there a while.
"I've always been one of his biggest fans, and I believe he'll get it done," Wedge said. "Right now, he's not getting it done -- and we're in the business of winning games.
"We're going to leave him down in the lineup, take some of the pressure off him."
Smoak, the key player acquired in the 2010 Cliff Lee trade with the Rangers, is batting .190 with three home runs and nine RBI this year. His career batting average coming into the season, in 223 big-league games, was .223.
"Smoak works hard, right now he's battling inconsistency," Wedge said. "You see something positive, but it changes at-bat to at-bat, sometimes swing to swing.
"I put Alex Liddi at first base today, let Justin be our designated hitter. That's just for today."
Jesus Montero started behind the plate for two consecutive games -- a first as a Seattle Mariner. In the day game today, John Jaso will catch for the first time in 2012.
Having carried three catchers all year, the Mariners now only have those two healthy, so on Wednesday Wedge "volunteered" an emergency third-string catcher.
"If I DH Montero or pinch hit for him -- and I will -- all we have is one catcher, and if something happens it's not good," Wedge said. "I looked around and picked Munenori. He'd do anything we asked."
Though he'd never caught before, Kawasaki -- all 5-foot-10, 165 pounds of him -- put on the gear and caught coach Jeff Datz in the bullpen before the game.
"He's more than willing and able to do it," Wedge said. "Brendan Ryan said he caught in high school and he volunteered. He said he was looking forward to calling a game.
"That's in my head now," Wedge said, laughing.
