It’s highly doubtful that having Edgar Martinez as their new hitting coach for less than five hours or his mere presence and aura in the dugout was the difference for the Mariners in their 6-3 win over the Astros.

It doesn’t work that way in baseball.

“He had a good first night,” joked manager Lloyd McClendon.

But what the victory did show is that Martinez will have some talent to work with — talent that’s capable of having nights like Saturday on a more consistent basis. It’s that frustrating unpredictability in performances that led the Mariners to make a change at hitting coach before the game. For the second straight night, they scored five runs or more, but it just the fifth time in the last 24 games they’ve scored more than three runs.

“I think there is a lot more to be had from this offense,” McClendon said. “The last two nights it was nice to see the guys grind at-bats, take their walks and get pitch counts up.”

Seattle beat up on Astros ace Dallas Keuchel more than any team has in his all-star level season, handing him just his third loss.

They worked over Keuchel for four walks total and three straight in the second inning — two of which came with the bases loaded for a pair of runs — and later belted three solo homers off him, ending his outing after six innings. The five earned runs, three homers and four walks were the most he’s given up all season.
