Question: Shaun White Wins Gold In Halfpipe At The Winter Olympics
Updated at 10:15 p.m.  ET
Shaun White  pulled off a gold-medal comeback in the halfpipe  and Japan's Ayumu Hirano won silver on the strength of a phenomenal second run.
CORRECTION: An early version of this story reported that  White  had won silver — that was reported after the second run had completed. On his third run   White  won gold.
 White  missed out on a medal back in 2014  when  he  was hurt at the Sochi Games.  He 's now the only snowboarder ever to win three gold medals at the Olympics. And  he  did it by winning the 100th gold medal for the U.S. Winter Olympic team.
After the Japanese snowboarder's rousing run  the pressure shifted to James and  White . James seemed to take a very deep breath before he set off on his second run. The first section was great — but he couldn't get a clean landing on one of his final tricks.  White  came out with energy and speed — but  he  fell midway through  and mustered only 55 points.
The situation reversed in the third and final run  when  White  earned a 97.75 and both of  his  top rivals fell during  their  attempts.
This is the second Olympic medal for Hirano; he won silver in Sochi. He is also the reigning X Games champion in the halfpipe  having won that title last month  in a competition that  White  skipped.
 White  led a group of four American snowboarders who qualified for the finals of the men's halfpipe at Phoenix Snow Park in Pyeongchang; joining  him  were Ben Ferguson  Chase Josey  and Jake Pates.
 Ferguson  cleaned up  his  second run after a fall in the first. And after a strong final run earned  him  a 90.75   he  finished 4th; Josey was 6th and Pates was 8th.

Answer: Shaun White


Question: FAIRFAX  Va. (AP) â Jon Axel Gudmundsson hit four 3-pointers and scored 24 points and  Davidson  took control early for an 86-59 win over George Mason on Sunday.
Pritchett had the first five points of an early 10-0 spurt that gave  Davidson  the lead for good  13-8. Grady had five in another 10-0 run that put the lead into double figures at 30-18. Gudmundsson then scored six in a third 10-0 run for a 45-24 lead before Livingston knocked down a 3 at the buzzer. The Wildcats shot 56 percent (18 of 32) and George Mason shot 42 (10 of 24) despite going 6 of 12 behind the arc.
Gudmundsson scored 15 points in the second half and  Davidson  shot 55 percent (17 of 31) for the easy win.
 Davidson  players had to Uber to the game after  their  bus broke down in the hotel parking lot.

Answer: Davidson


Question: Kevin Garnett suffered a strain in his right mid-foot during Monday's Game 2 victory over the Cavaliers  while Kendrick Perkins hyperextended his right knee in that day's shootaround  though he still managed to play.
 Garnett reported to practice Wednesday and wanted to participate  telling Rivers he felt better  but that did not convince the coach. Perkins suited up but did not participate in drills and eventually left for treatment. He returned to the court following the team's workout and said he will be ready for Game 3 Friday.
 "After the game Monday it was hurting  and even more when I woke up the next morning " Perkins said. "It's still a little sore in my hamstring area. I am glad we had a few days to rest and hopefully I'll practice tomorrow. I'll be ready for Friday. I am glad we have a few days to rest."
 Garnett's injury is the more serious of the two. He was hurt in the second quarter of Game 2 when Perkins backed into him while defending a drive by Anderson Varejao. Paul Pierce suffered a similar injury Feb. 1 against Washington and missed two games  but the Celtics are hoping the extra rest will make Garnett available for Game 3.
 Perkins said he tweaked the knee simply running down the court. Still  his defense against Shaquille O'Neal has been effective. The Celtics have used Garnett and Perkins to plug up the middle and reduce the inside scoring of O'Neal  Antawn Jamison  and Anderson Varejao.
 O'Neal hurt the Celtics in the fourth quarter of Game 1 but is 8 for 22 in the series and Perkins has limited his easy chances at the rim. If O'Neal gets even a few steps from a dunk  Perkins is helpless to stop the 325-pound train.
 "The biggest thing with Shaq is  you don't let him get deep post-ups " Perkins said. "You try to fight him as much as you can and make him score over the top and no dunks  no layups. That's the game plan."
 When asked if O'Neal chatters during their matchup - which already has cost Perkins five stitches in his upper lip - Perkins said  "Nah  he doesn't talk. Shaq really don't talk. He just plays hard and just a big body that plays physical."
 The Celtics are hoping the physicality of the first two games won't cost them a starter  but they have been accustomed to playing shorthanded all season  so there is no sense of panic. Garnett has been remarkably healthy since the 10-game absence  playing in 39 straight before Rivers rested him for two of the final three regular-season games.
 Rivers is cautious when it comes to injured players practicing  so keeping Garnett away was no surprise.
 "This is just like a normal practice  not enough guys  that's the way it's been all year for us " said Rivers. "It was an easy practice because we knew what we had."

Answer:
Rivers Kendrick Perkins
