SEATTLE -- Mariners catcher Jesus Montero wants to finish his first full season in the Majors in strong fashion, but the 22-year-old has struggled the past week while hitting .156 (5-for-32) over his last seven games. Manager Eric Wedge had Montero behind the plate Saturday against tough Rangers lefty Matt Harrison and is looking for the youngster to fight through things in the season's final four series. "We've seen some lack of discipline at home plate," Wedge said prior to Saturday's game with the Rangers. "He's swinging at pitchers' pitches, getting in a hurry up there. I think he's showing his frustration from time to time.
"He's had some young moments lately," said Wedge. "But he's got to fight through it. He can't give into it. That's the challenge that is ahead of him for the next 11 games." John Jaso has started just once in the past six games, despite his team-leading .277 batting average, as the Mariners have run into a steady string of left-handed pitchers. Jaso has hit .135 against lefties (5-for-37) and .300 against right-handers (69-for-230), though Wedge said it's not a 100-percent situation of Jaso sitting against southpaws. "I don't look at it as an automatic sit," Wedge said. "I know I've done that a lot. But I'm not saying he can't compete against left-handers, because he's got too good of an approach. Where we are right now and what we're trying to do, I've been doing that more times than not, for other reasons that I won't get into. But I like when he's up at home plate."
