Notebook | Mariners might be running out of patience with Carlos Silva

Even though Carlos Silva's disappointing performances have yet to really hurt the Mariners this season — he is 1-2, while they are 3-2 in his starts — manager Don Wakamatsu won't wait forever for the right-hander to turn it around.

Silva allowed six runs in 3-2/3 innings on Friday, the fourth time in five starts he failed to get out of the fifth inning. Silva's earned-run average has inflated to 7.36, which, put on top of last season's 6.46 ERA, has heightened concerns about where his season is headed.

"At some point, he is going to have to make some adjustments," Wakamatsu said. "If not, we have to make adjustments. But at this point, going forward, is that rope shorter? Yeah. At some point he's going to have to come out and give us some good outings."

Wakamatsu said the Mariners "believe in [Silva's] stuff," and that Silva's velocity hasn't been a problem. But Silva's "stuff" is not translating into quality starts.

"The mental side of this game is so devastating — can be, if you allow it," Wakamatsu said. "He has some skeletons in his closet, obviously, from the failures he's had here and disappointments from last year. But you keep trying to hammer away and build his confidence, saying, 'It's up to you. At what point are you going to believe, is your confidence level going to match your stuff?' "

A little catching up

After the play at the plate that decided Saturday's game, catcher Rob Johnson talked to Wakamatsu about what he could have done differently on the throw that short-hopped into Johnson's chest. On such a quick play, Wakamatsu only had a few small technical suggestions.

"To say he did anything wrong is not correct," said Wakamatsu, a former catcher.

The manager could relate to the plight of Johnson, who got run over by Oakland's Bobby Crosby on the play.

"I got my left ear lobe ripped halfway off and a sprained neck, so I know exactly what it feels like to get hammered there," Wakamatsu said.

Notes

• RHP Brandon Morrow (right biceps tendinitis) threw a bullpen session Saturday and will likely throw two more before coming off the disabled list Saturday.

• INF Ronny Cedeno (strained hamstring) is back to full health, and Wakamatsu expects him back soon.

• LHP Ryan Rowland-Smith (left biceps tendinitis) will throw a bullpen session today, and should throw a simulated game sometime this week.
