Less than a week remains for teams to acquire players by the Aug. 31 deadline for them to be eligible for the postseason roster, but the Cardinals’ pursuit of an addition has remained as difficult as it was in July before the non-waiver deadline.

For players to be moved during this month they must be claimed off waivers or clear waivers. Only then can teams work out trades, and Cardinals general manager John Mozeliak said recently the trade requests have been "as high as they were in late July.”

Former Cardinals starter Kyle Lohse did not clear waivers. FoxSports.com reported that the Braves claimed him, but Milwaukee pulled him back with no interest in trading him to Atlanta.

Washington’s surging starter Dan Haren cleared waivers and can be traded to any team, but the Nationals want a group of prospects.

They can position as if they’ll get draft-pick compensation for Haren even if they have no plan to offer him a qualifying contract. It remains a seller’s market.


• Cardinals starter Jake Westbrook played catch Sunday and said he hopes to begin bullpen sessions this week. He’s eligible to come off the DL in early September. …

• Braves third baseman Chris Johnson was a late scratch from Sunday’s lineup with a toe injury. He collided with Allen Craig during Saturday’s game. 

• In their last head-to-head series of the regular season, Molina maintained an edge on Johnson for the batting title, .335 to .331.
