Two of the top young running backs in the NFL will share the field in San Diego on Sunday.And both players were considered huge question marks entering the season after disappointing rookie campaigns.San Diegos Melvin Gordon is finally living up to his star billing, while Miamis Jay Ajayi came out of nowhere to become one of the NFLs top rushers. Those developments add plenty of luster to Sundays matchup (4:05 p.m. ET, CBS) between the Chargers (4-5) and Dolphins (4-4).Gordon is coming off the top game of his career, a 196-yard rushing effort against the Tennessee Titans that boosted him to third in the NFL with 768 yards. He also leads the league with 11 touchdowns (nine rushing, two receiving) after failing to find the end zone as a rookie.Ajayi is in the midst of a superb three-game frenzy in which he has rushed for 529 yards, a stretch that saw him become just the fourth player in NFL history to post back-to-back 200-yard outings. He ranks sixth in the NFL with 646 rushing yards and is averaging a sparkling 6.0 yards per carry.Turns out the two 23-year-olds have a close friendship, stemming from working out together prior to the 2015 NFL Draft.Im always checking on Melvin every week to see how he does, Ajayi said. Im so proud of him to come back from last year, where he wasnt able to score a touchdown and a lot of people were kind of starting to write him off a little bit.Through talking with him through the offseason and everything, he really put his head down and did a lot of things to set himself up for a great year. Hes starting to showcase the ability that everyone knew he had, and its exciting to see how well he has been doing.Gordons rushing output against Tennessee was the ninth most in Chargers history, and he added 65 receiving yards to give him 261 total yards.He already has passed last seasons total of 641 rushing yards. Gordon also has erased last seasons image as a fumbler -- he lost four of the five he put on the ground -- and coach Mike McCoy now repeatedly refers to him as the teams bell cow.Every guy wants to make a play, Gordon said. Every guy wants you to look at him and think, I can count on this guy. Thats how we all want to be. When you get the opportunity to have the ball in your hands, its your job to make something happen.Ajayi is making things happen as well after opening the season as a healthy inactive against the Seattle Seahawks. Arian Fosters injury issues -- and eventual retirement -- opened the door for Ajayi, who responded with outings of 204 yards against the Pittsburgh Steelers, 214 versus the Buffalo Bills and 111 against the New York Jets during the clubs three-game winning streak.The play of rookie left guard Laremy Tunsil helped fuel Miamis rushing success. Getting Ajayi loose could be a challenge on Sunday with San Diego ranking fifth in the NFL in rushing defense at 85.3 yards per game.Rookie defensive end Joey Bosa is making an impact on the Chargers defense, as he has four sacks in five games. Cornerback Casey Hayward, tied for the NFL interceptions lead with five, and outside linebacker Melvin Ingram, who has a team-high five sacks, also are enjoying standout seasons.San Diego quarterback Philip Rivers is feeding off the improved run game, throwing for 2,560 yards and 17 touchdowns against seven interceptions.Dolphins quarterback Ryan Tannehill is experiencing a relatively quiet campaign by passing for 1,877 yards and eight touchdowns against seven interceptions. He has passed for just 605 yards during the three-game winning streak that has been highlighted by Ajayis emergence.Miami ranks just 30th in defending the run (136.1 yards per game) despite the presence of defensive tackle Ndamukong Suh. Veteran defensive end Cameron Wake has a team-best five sacks, including four in the past three games.The contest also marks the first time that McCoy and Miamis Adam Gase will square off as head coaches. The two spent four years together on the Denver Broncos staff before McCoy became the Chargers coach in 2013.Another backdrop is that the contest is San Diegos first at Qualcomm Stadium since the citys voters overwhelmingly said no to a ballot measure to fund a $1.8 billion downtown stadium. The franchises future home is once again in limbo.As you can imagine, were all disappointed, Rivers said. In the midst of a season, you cant get too caught up in it.Rivers passed for 311 yards and three touchdown passes last December when the Chargers sailed to a 30-14 victory over the Dolphins.

LOUIS -- Dave Ryan and Matthew Sughrue each won two matches Wednesday at Old Warson to reach the U.S. Senior Amateur final.The 62-year-old Ryan, from Taylorsville, Illinois, beat Michael Dunsmore of Poughkeepsie, New York, 5 and 3 in the quarterfinals and topped Tim Jackson of Germantown, Tennessee, 1 up in the semifinals.I dont know what to say. Im at a loss for words, Ryan said. To be honest with you, Im a little shocked. I was fortunate to beat him (Jackson) and Paul Simson (in the round of 16). Those are two tough guys to take down.The 57-year-old Sughrue, from Arlington, Virginia, edged Doug Hanzel of Savannah, Georgia, 1 up in the quarterfinals and rallied to beat Kevin Cahill of Waukesha, Wisconsin, in 19 holes in the semifinals.Against Jackson, Ryan won the 14th to take a 2-up lead, lost the 15th with a bogey and matched Jackson with a par-birdie-par finish -- holing a 9-footer on 18 -- to close out the match.It was uphill and I just had to hit itt, Ryan said.dddddddddddd Fortunately, it went in. Thats a tough hole.On Tuesday in the round of 16 against two-time champion Simson, Ryan had the third known hole-in-one on a par 4 in USGA history.Against Cahill, Sughrue lost 15 and 16 to fall 1 down, won the 18th with a par and won the match on the 19th with another par. Sughrue also rallied against Hanzel, winning 15 and 16 to take the lead and matching Hanzel with pars on the last two holes.The Hanzel match was a real grinder. It was a tough match against a great player, Sughrue said. We didnt play as well in this one, but on the back nine, we both kind of steadied, and coming down the stretch, its not stroke play, its a matter of who wins the match.Sughrue left the insurance business after 25 years in 2008 to go to graduate school at Virginia Tech and is now a psychotherapist.
