In his last start, Meche gave up a season-high seven earned runs and nine hits in 4 1-3 innings of a 8-1 loss to the Boston Red Sox on Monday.
The defeat was the third straight and seventh in 10 decisions for Meche, who was 10-3 through June.
On Saturday, Meche will get his fourth chance at becoming the first pitcher since 1956 to win 14 games after missing two straight major league seasons. He missed all of the 2001 season after undergoing arthroscopic surgery on his right shoulder and pitched in 25 games, including 13 starts, for Double-A San Antonio last season.
The Mariners could certainly use a strong outing from Meche as they have won just two of their last 10, including a 3-2 come-from-behind win on Friday. They are also hoping John Olerud’s game-winning, two-run single will be a turning point.
“We’ll see. I hope so,” said Olerud, the team’s most understated player. “We want to get this turned around as soon as possible, get on a good winning streak. Hopefully, it’s a game that turns things around.”
The Mariners remained two games behind the Oakland Athletics, who won their seventh straight on Friday, in the AL West. Seattle led the West for most of the season before Oakland took sole possession on Wednesday.
Seattle also remained a half-game behind the Boston Red Sox, who beat the New York Yankees 10-5 Friday, in the AL wild-card race.
