The PGA TOUR Season has reached its midway point. There are 18 events in the books and 18 remaining before we reach the FedExCup Playoffs. Below are some of the numbers that have helped define the 2013 season to date.
Lowest 18-hole rounds of 2013:
A 59 was cruelly taken away from Phil Mickelson with a brutal final-hole lip-out at TPC Scottsdale during the first round of the Waste Management Phoenix Open. Mickelson didn't fret over it long, however, as he went on to become the season's only wire-to-wire victor thus far. Here's a look at some of the other stellar rounds from the first half of the season.

Best come-from-behind victories:
At this time a season ago, four players had already made 6-or-more stroke comebacks on the final day to win. The rallies haven't been as grand, but there has been no shortage of drama on TOUR thus far in 2013.
|6 strokes||Brian Gay||Humana Challenge|
|5 strokes||Martin Laird||Valero Texas Open|
|4 strokes||Graeme McDowell||RBC Heritage|
Just nine players earned their maiden TOUR victories in 2012 but we're two-thirds of the way there in just the first half of 2013.
|Russell Henley||Sony Open in Hawaii||Scott Brown||Puerto Rico Open|
|John Merrick||Northern Trust Open||Kevin Streelman||Tampa Bay Championship|
