From TBredIQ's own results records; may be incomplete before Jul 3, 2023. Matched on name, sire and dam. Finish shows lengths behind the winner where we have the chart; odds are final odds where we have the chart, otherwise the morning line (ML). Past race pages aren't kept on the site, so there's no result link for these races. 7 other entries in our records have no result (usually a scratch, or a race we have no chart for) and are not listed.
