	// First, we make sure we're in the grid loop.
	if( ! apply_filters( 'is_genesis_grid_loop', false ) )
		return;
		
	if( in_array( 'teaser', get_post_class() ) ) {
		remove_action( 'genesis_entry_header', 'genesis_do_post_title' );
		// remove_action( 'genesis_entry_header', 'genesis_entry_header_markup_open', 5 );
		// remove_action( 'genesis_entry_header', 'genesis_entry_header_markup_close', 15 );
	}
	
}
add_action( 'genesis_before_entry', 'be_remove_post_title_in_grid' );

This will remove the post title from "teaser" posts in the Genesis Grid plugin. If you remove the // from lines 15-16 it will also remove the entry-header markup
