Worth noting

• Though McClendon said the Mariners likely will want to add a position player back to their 25-man roster by Aug. 18 when they go on the road to face Philadelphia in a three-game Interleague series, he's not sure utility infielder Willie Bloomquist will be ready to come off the 15-day DL by then. Bloomquist is eligible to return from a bruised right knee on Friday, but he is still rehabbing the knee in Seattle.

"We'll see," McClendon said. "My understanding is his progress is not happening as quick as they initially thought."

• The Mariners' ERA of 3.06 going into Saturday's game not only leads the American League, it would shatter the franchise low of 3.54 set in 2001 if they can maintain it through the end of the season. The last AL club with an ERA under 3.10 for a season was the 1989 World Series champion A's.
