MIAMI (AP) — A seven-game trip this week robs the Florida Marlins of their biggest weapon: the game-ending hit.

Four walkoff wins during a wild homestand buoyed the Marlins' slim playoff hopes and made it less likely they'll unload starters before Saturday's trade deadline.

The Marlins went 7-3 on the homestand, with six wins by one run.

With the trade deadline looming, management has been undecided about whether to buy or sell. Postseason chances will help determine whether the cost-conscious franchise unloads some of its higher-priced talent.

The Marlins haven't been above .500 since June, and they're 49-49 as they start a West Coast trip in San Francisco. But the players still consider the team a playoff contender.
