SAN FRANCISCO -- Oh, Buster Posey knew all about how long he had gone without a home run.Yeah, Ive had a few reminders over the last week or two, Posey said with a chuckle.All that talk about the star catchers second-half power drought was answered with one mighty swing in a September game that mattered, and his two-run shot helped the San Francisco Giants beat the St. Louis Cardinals 8-2 Friday night in a matchup of playoff contenders.Posey drove in four runs and the Giants stayed four games back of the NL West-leading Los Angeles Dodgers, who won at Arizona. San Francisco maintained its one-game lead over the New York Mets for the leagues top wild card, moving three games up on the Cardinals in the wild-card standings.Left-hander Matt Moore (4-4) allowed two runs over five innings, struck out four and walked three while facing the Cardinals for the first time in his career. He won for the fourth time over five starts in his ninth outing since joining San Francisco in a trade with Tampa Bay.Posey was all smiles in the dugout after his fourth-inning drive, his first home run in 185 at-bats and exactly two months -- he last connected on July 16 at San Diego.It was a good feeling, he said.Posey also had a two-run single and followed up his four-hit game Thursday night with three more.It was great to just see him start smiling and laughing after he touched home plate, Brandon Belt said. Its kind of out of the ordinary with him. Hes pretty stone-faced most of the time. When you know what hes capable of doing and when hes had a stretch like hes had, its good to see.Belt hit a two-run double to highlight San Franciscos six-run third. Posey singled in a pair of runs that inning, when all the runs were unearned off rookie right-hander Luke Weaver (1-3).For the second straight day, Giants manager Bruce Bochy gave his team a late report time to the ballpark and the players went without batting practice. This time, it came on the heels of Thursdays 6-2 victory behind Johnny Cuetos five-hitter.A couple days off the field will serve them well, said Bochy, who is sticking with the same routine for Saturday nights game.It proved the right call again. After a demoralizing three-game sweep by San Diego earlier this week, San Francisco suddenly looks like a playoff team again. The Giants have had World Series-winning seasons in every even year this decade: 2010, `12 and `14.Weavers night was done after 2 2/3 innings and he is winless in four starts since beating Oakland on Aug. 26. He allowed five hits, struck out four and walked two.Yadier Molina drove in both runs for the Cardinals, including a bases-loaded walk in the fifth.We just have to play better, thats all there is to it, manager Mike Matheny said. The standings are the standings and we know what they are. You cant run from them, hide from them. The standings say were right there, so just keep playing the game. Thats all it is. Same as always.Denard Span hit eighth for the Giants again after his strong performance, with a two-run single among his two hits in that spot a night earlier.NINTH-INNING DELAYA fan ran on the field in the top of the ninth and a member of security who slid approaching the man had to be helped off the field with an injury.TRAINERS ROOMCardinals: OF Matt Holliday will face live pitching Saturday with the hope he still might return from a broken right thumb as St. Louis makes a playoff push. The slugger hasnt played since Aug. 11, when he was hit by a pitch in an 11-inning loss to the Cubs. He had surgery to insert a screw for the fracture. Id love to play but I cant do it at jeopardizing putting my finger in a bad situation, Holliday said. Its clearly not 100 percent. Its still fractured but theres a screw in there. Its more stable than it would be if I had not had the surgery. ... SS Aledmys Diaz returned to the lineup after being held out Thursday. He came off the disabled list Sunday after he had been sidelined since July 31 with a broken right thumb, and the medical staff and Matheny are being cautious to determine if Diaz can handle playing every day.Giants: The team activated OF Gregor Blanco from the 15-day disabled list after he missed 22 games with a right shoulder impingement. ... Bochy has been looking to rest Posey and will aim to give him a break in Sunday afternoons series finale following a night game Saturday.UP NEXTCardinals: RHP Mike Leake (9-10, 4.60 ERA), who spent the second half of last season with San Francisco, looks for his second win in seven starts since July 29.Giants: RHP Jeff Samardzija (11-10, 4.07) seeks his first victory in four starts since Aug. 26.

If he can repeat that kind of performance, suspended Zlatan Ibrahimovic and captain Wayne Rooney could have a real problem on their hands. This is a massive chance for him to give United a completely different dimension that theyve been lacking with those two older players in the side. Rashford can put himself right to the top of the pecking order if he plays well on Saturday. Jamie Redknapp There have been times this season when Ive looked at Rashford and wanted a bit more from him. Hes generally been restricted to a wide role but hes not been as sharp as he was last year.Maybe thats because he feels he should be starting, rather than being used from the bench. Maybe he feels he should be playing centre forward, rather than out wide. It may be born out of frustration.But if he gets his chance tomorrow there will be no excuses. It will just be a great platform for him to go out and show what he can do. He may feel like he needs to prove himself again - but he can put himself right to the top of the pecking order if he plays well on Saturday. Theres no doubt in my mind hes a striker rather than a wide man. We had Ryan Giggs on Sky Sports a couple of months ago and he agreed. Rashford is a goalscorer, has good feet and the pace you need if you are going to be the most advanced player.I know Ibrahimovic got a couple of goals against Swansea last time out, but theres a need for a change in Uniteds attack. The fans are crying out for something different. And what a buzz around the stadium there would be if they saw the teamsheet with Rashford at No 9.It would be a real statement from Jose Mourinho about how he wants his team to play and would earn a lot of good will from the United supporters. Watch some of the best goals scored in Premier League fixtures between Man Utd and Arsenal Of course, Mourinho may be tempted to play Rashford up against Carl Jenkinson, who will come in for the injured Hector Bellerin at right-back for Arsenal.ddddddddddddJenkinson is a good player but he hasnt had much game time recently and United will want to test him out.But that job could be performed by Anthony Martial. This could be the game where the Frenchman turns it on, runs at Jenkinson - who is quick himself - and tests out the replacement right-back to see if theres a weakness there.That could be a key factor in whether United can open Arsenal up and get a much-needed win. Arsenals travel trouble Arsenal players travelled over 18,000 miles further than Man Utd players during the break The key for the Gunners is not to get beaten on Saturday. Arsene Wenger would love to turn around that record he has against Mourinho sides but if you offered him a point I reckon hed take it. Its more important for United to win, given the start theyve had.Alexis Sanchez could deny them - should he be in good enough condition to start, following his long journey to South America and back - and his link-up play with Mesut Ozil this season has been excellent.But I can see this one being a tight game and reckon the points will be shared.
