SAN FRANCISCO -- Both teams will begin with question marks and end with uncertainties when the St. Louis Cardinals and San Francisco Giants meet in the finale of a four-game series on Sunday afternoon.The game is a big one for both teams, but especially for the Cardinals, who trail the Giants and New York Mets by two games in the race for two wild-card playoff spots in the National League.A win Sunday not only would allow the Cardinals to close the gap on the Giants, but also would secure a 4-3 win in the season series, which would give them the home-field advantage should the two teams finish in a tie for a wild-card spot.There are only 14 games remaining in the season.I can feel it, and I know the guys can feel it, Cardinals manager Mike Matheny said of the pressure of the playoff race. We know where everybody stands.But neither manager can even pretend to know what hes going to get from Sundays starting pitcher.Each will be going with a rookie who has never faced the other team -- the Cardinals Alex Reyes and Giants Albert Suarez.Reyes has made only two previous major league starts, and didnt win either. He pitched well, giving up just three runs in 10 2/3 innings, but those games were against two of the worst teams in baseball, the Oakland Athletics and Cincinnati Reds.Suarez, meanwhile, has more of a track record, having gone 3-3 in 20 appearances, including 10 starts.He appeared to be in good shape to win a fourth game in his last start Tuesday, but the Giants bullpen blew a 4-1 lead in the ninth inning and the club dropped a 6-4 decision to the San Diego Padres.The Giants bullpen hasnt gotten any better since then. Three relievers combined to give up two hits, a walk and two runs in the Cardinals ninth-inning rally Saturday night that might have saved their season.It surely didnt save closer Santiago Casillas job. After Giants manager Bruce Bochy didnt have the confidence in him to start the ninth inning with a 2-1 lead, Castilla wound up blowing the save anyway after entering the game with one on and one out.Bochy was booed when he went to the mound to bring Casilla into the game, and booed louder when he had to go back and pull him two batters later.I understand in this game, everybody likes it when you do good. But then they forget what you do, Casilla said after the loss. I never have that moment (boos) before. So when we lose the game, its not so easy. So I feel bad.Cardinals manager Mike Matheny, meanwhile, used his best reliever, Seung Hwan Oh, two innings Saturday night, which makes him unlikely to be available in the series finale.Matheny also has former closer Trevor Rosenthal at his disposal. But Rosenthal said he felt sore after pitching one inning Friday night in his return from the disabled list, so he also might not be ready for work Sunday.

Murrays march to the final of the Paris Masters, coupled with Novak Djokovics quarter-final exit to Marin Cilic, means the 29-year-old will take over from the Serb at the top of the world rankings on Monday.And Sky Sports tennis expert Petchey, who coached Murray during the early stages of the Scots career, says the three-time Grand Slam winner is finally being rewarded for years of hard work. Andy Murray says hes proud after becoming the world number one, replacing Novak Djokovic after 122 weeks For me its his greatest ever achievement, Petchey told Sky Sports News HQ. Its a lifetime of work for his finest hour. There is so much that goes into being world No 1 anyway, but also at this stage of his career at 29, the fact he has just been behind Novak, Roger [Federer] and Rafa [Nadal] throughout the course of his career, to finally get to the summit of mens tennis underlines just how much Andy is willing to sacrifice and persevere and be patient. Live Tennis: ATP World Tour Finals November 13, 2016, 12:00pm Live on Get Sky Sports Get a Sky Sports pass All those ingredients go in, which is why for me it is his greatest achievement.Petchey is confident Murray will not rest now he is at the summit.The one thing about Andy is he will never relax, Petchey added. He always wants to get better and better and thats why hes become such a great champion. Murray won Wimbledon for a second time in the summer Speaking to his coach Jamie Delgado, after Wimbledon they went doown to the Nadal Academy and his team were just blown away by the work ethic that he put into the training sessions there, after winning Wimbledon.dddddddddddd. That is the reason why this week we see him as world No 1, because there was no let down, he went straight back and worked.Petchey also believes the duel between Murray and Djokovic ensures an exciting end to the season, with both players battling to finish the year as the worlds best player. Novak Djokovic says Andy Murray deserves to become the world number one after raising his level in the last year The fact that the world No 1 is on the line for the World Tour finals is great and will be a spur for both players to produce their best tennis in the next couple of weeks, Petchey added. For Andy, to finish the year as world No 1 is a big deal. Lots of players have won a Grand Slam but failed to get to get No 1 at any stage of their career; there are even fewer players that have ended up year-end No 1 and for Andy to be able to achieve that will be enough of a drive for him continue this fantastic run. Murrays next aim is to end the year as world No 1 When he was 18, he didnt love the hard work. He always loved to play tennis, but now, he loves to work hard physically. He would have had a good career, he was that talented, but he wouldnt have become unique without investing in that hard work and growing on a daily basis to love it. Now hes arguably the hardest worker mens tennis has ever seen.Check our game-by-game updates from Andy Murray v John Isner from the ATP Paris Masters final and then follow his progress at the ATP World Tour Finals from London skysports.com/tennis, our app for mobile devices and iPad and our Twitter account @skysportstennis.
