Also, the 10th tee was moved well left so the players tee shot has a longer carry over water, the par-3 15th was shortened, but more water was added into play, and the 16th was also shortened, but water was moved closer to the green.
World No. 1 Tiger Woods cruised to his seventh title at this event last year. He was 13-under par after two rounds and only needed a 71 in the final round to win by two strokes over Steve Stricker.
Woods' health is a big question mark this week though. He withdrew from The Honda Classic during Sunday's final round with a back injury. At this point, he remains in the field.
Woods has won this title seven times overall, including five in a six-year span from 2002-07.
If Woods can't go, the field will still have four former winners - Justin Rose, Nick Watney, Ernie Els and Phi Mickelson. If Woods does remain in the field, all 50 from the current world rankings are slated to tee it up together for the first time since 2012 PGA Championship.
Thanks to his win Sunday at The Honda Classic, Russell Henley will make his second straight appearance at this championship. He failed to break 70 last year en route to tying for 28th.
