In 2009, Couples limited his play but performed impressively at the Northern Trust Open. If it wasn't for Phil Mickelson shooting a 62 on that Saturday, Couples may have won instead of finishing third. He nearly won the Shell Houston Open but bogeyed the last three holes and finished third behind Paul Casey. He also played well at the HP Byron Nelson Championship (T8) and the AT&T National (T11) tournaments. He hurt his back practicing for the RBC Canadian Open and had to withdraw. But he rested and recovered and made the cut for the PGA Championship (T36) and performed successfully in the Wyndham Championship (T5) which put him past the $1 million mark on the money list for the 7th time in his career.
