The Boston Marathon bombings in April was voted The Associated Press top story of 2013 in balloting by 96 U.S. editors and news directors.

Voters were asked to rank the top 10 sports stories of the year, with the first-place story receiving 10 points, the second-place story nine points and so on.

The top five stories were grim in nature, with Lance Armstrong admitting to using performance-enhancing drugs at No. 2; the NFL's concussion lawsuit settlement with former players at No. 3; baseball's drug bans, most notably Alex Rodriguez, at No. 4; and New England Patriots tight end Aaron Hernandez being charged with murder at No. 5.

Rounding out the top 10 were the Boston Red Sox winning the World Series title, the Baltimore Ravens beating the 49ers in the Super Bowl, Auburn's turnaround season, the Manti Te'o girlfriend hoax and the Miami Heat repeating as champion.

Certainly no story was as terrifying and haunting as the 118th edition of the Boston Marathon on April 15. Two pressure cooker bombs exploded near the finish line in an area packed with fans cheering the passing runners. Three people were killed and more than 260 injured, including at least 16 who lost limbs.

Authorities say brothers Dzhokhar and Tamerlan Tsarnaev, ethnic Chechens from Russia who emigrated to the United States as children, planned and carried out the bombings in retaliation for U.S. involvement in Muslim countries.

Tennis

Novak Djokovic overcame Jo-Wilfried Tsonga to enter the final of the Mubadala Championship in Abu Dhabi, United Arab Emirates, for the third time in three years, but he won't be facing top-ranked Rafael Nadal.

Djokovic beat Tsonga 7-6 (5), 6-3 in 74 minutes to set up a repeat of last year's final against David Ferrer, who knocked out Nadal 6-4, 6-4 with breaks in the last game of each set, in 90 minutes of quality tennis.

Winter sports

Jonathan Kuck claimed another trip to the Olympics with a dominating victory in the men's 5,000 meters at the U.S. speedskating trials in Kearns, Utah.

Kuck won with a time of 6 minutes, 19.75 seconds, almost six seconds ahead of runner-up Emery Lehman.

Patrick Meek was third and probably will join Kuck and Lehman on the Olympic team when it is announced New Year's Day.

Jilleanne Rookard won the women's 3,000 meters with a strong time of 4:09.66 seconds, more than four seconds ahead of second-place Anna Ringsred.
