Horses that have high career earnings also can be good candidates for wagers, although it always must be noted that past performance does not necessarily predict future performance. If a horse has been away from the track for several weeks, it might be weaker than normal and not a good candidate for a wager. But one that has been run regularly and that has proven to be a good earner might be a good candidate for a box exacta or trifecta and possibly to win and provide a big payout, particularly if there are similarly strong-running horses on the bill.
