Five months without competition, and Tiger Woods was grinding over key shots and big putts Friday at the Memorial. After his second-round 4-over 76, the 44-year old admitted that "aging is not fun." However, the former world number 1 did just enough to make the cut on the number at 3-over 147, though that was his highest 36-hole score at Muirfield Village since his Memorial debut in 1997. Ryan Palmer (68) and Tony Finau (69) managed just fine and were tied for the lead, leaving Woods 12 shots behind going into the weekend.
