Messi kickin' it at the top

Lionel Messi has been a staple in the Cross-Sport Power Rankings with the year he's been having, and for the fourth time the Argentine footballer garnered the top spot. Messi received top billing after breaking German great Gerd Mueller's 40-year-old record for most goals in a year by scoring for the 86th time in 2012. The phenomenal forward tied the record with a goal in the 16th minute and then broke the 1972 milestone by netting another one nine minutes later.

Landing in the No. 2 position was Juan Manuel Marquez, who delivered a knockout punch to Manny Pacquiao in the final seconds of the sixth round, winning for the first time in four fights with Pacquiao. Johnny Manziel took the No. 3 spot for becoming the first freshman to take home the coveted Heisman Trophy.

Rounding out the top five was Kobe Bryant, who became the fifth player in NBA history to score 30,000 career points, and Giants rookie running back David Wilson, who had his own record-setting performance.
