Mariners manager Eric Wedge called a team meeting before batting practice Saturday at Safeco Field to discuss Friday's 5-0 loss to the Boston Red Sox.

"What happened last night was unacceptable," Wedge said. "It's simple as that. ... The level of play at this level that I expect has to be better than that."

Aaron Cook, who came into the game with a 9.39 earned-run average, threw only 81 pitches in a two-hitter. In a difficult place to hit home runs, the Red Sox hit four, accounting for all their runs.

"You've got to play every day like it's your last, and some of the people out here need to be playing every day like it's their last," Wedge said of his team.

He didn't give much insight into the team's response in the clubhouse and didn't give a timetable on when he expects to see a difference.

"There's just a certain way we're going to go about things here," Wedge said. "I didn't bring my butt all the way out here to do it any other way. And we are going to be a championship team. Whether it's with all these guys or some of these guys is yet to be determined. But there's a vision here."

Shortstop Brendan Ryan shared Wedge's frustration after Friday's loss. He was upset adjustments weren't made against Cook, a sinkerball pitcher.

"He's pretty reserved for the most part," Ryan said about Wedge's dugout demeanor. "When he feels he needs to spark us and get a little vocal, he'll do that. Supportive after good swings and quiet after the bad ones. I'd be pulling my hair out to see what we've done this homestand."

Before Saturday's game, the Mariners had scored five runs in their past five home games. They were 14-22 at home with a .197 batting average and .291 slugging percentage.

"When we get to the point where we're winning more games than we're losing, these fans are going to show up here and we're going to be in a position economically to where we can hang onto the players that we want to hang onto," Wedge continued.

"If this isn't one of the three most important things in your life, then you should go do something else."

Notes

• Wedge said OF Michael Saunders could be back in the lineup Sunday. He was sent home Friday with flu-like symptoms.

• Wedge said the Mariners will be patient with the recovery of OF Franklin Gutierrez, who left Thursday's game with a mild concussion after being struck in the face by the ball on a pickoff attempt. He was placed on the seven-day disabled list Friday.

"There's no guarantee the seven days will be enough, but we'll tack on another seven (days) if we have to," Wedge said. "Obviously, we're going to be very careful with that."

• Mariners pitchers allowed two or fewer runs in six straight games from June 23 to 28, the longest stretch in baseball this season and second-longest in club history. The team's longest streak is seven games, from May 16-22, 2011.
