BOSTON -- Back home and rested, David Ortiz isnt ready to look at the second half of the season as the final stretch just yet.Ortiz drove a three-run homer deep into the seats in right field and Rick Porcello remained unbeaten at home as the Boston Red Sox beat the struggling San Francisco Giants 4-0 on Tuesday night.It was the 23rd homer and first since the All-Star break for Ortiz, who is keeping Boston in contention for another title in his farewell season.I can do all the thinking after the season is over, said Ortiz, who plans to retire once the season ends. Not thinking about nothing now.Otizs homer in the fourth and a solo shot by Brock Holt in the third were more than enough offensive support for Porcello to remain unbeaten at home this season.Porcello scattered four hits over 6 1/3 innings and the Red Sox won for the seventh time in eight games despite a strong start by former teammate Jake Peavy.San Francisco remained winless since the All-Star break with its fourth straight loss. The Giants had just five hits and only three runners advanced beyond first base.We just need somebody to get a big hit and inject some life into this offense, Giants manager Bruce Bochy said. We look flat right now. You look flat when you dont hit or drive in a run and they start pressing a little bit and weve got to get on track here soon.Porcello (12-2) scattered four hits over 6 1/3 innings, striking out three and walking two while improving to 9-0 at home. Porcello settled down after allowing singles to the first two batters he faced and improved to 9-0 at home this season.Porcello ended up striking out the side in the first and the Giants had two hits over the next five innings. Porcello left after walking Jarrett Parker with one out in the seventh. Reliever Robbie Ross got a quick double play to end the threat.Peavy (5-8), a key member of Bostons 2013 World Series champions, struck out six over six innings and held his former teammates to three hits, but two left the park.Ortiz nearly hit one out in his first at-bat, but the wind knocked it down for a very deep flyout to center. Ortiz came up again in the fourth and drove the first pitch he saw from Peavy way out to right.Hes a year too late if you ask me in retiring, Peavy said with a smile. Id love to play that game without him tonight.Holts solo homer to center in the third was Bostons first hit.Dustin Pedroia led off the fourth with a walk and Xander Bogaerts followed with a single, setting up Ortizs shot to right that cleared the bullpen and several rows of seats before finally landing.It was the 526th career homer for Ortiz, who didnt seem to relish hitting it off Peavy.Peavys always going to be remembered here and welcomed to Boston, Ortiz said. Great teammate and great personality. I really enjoyed being his teammate.The Giants were in Boston for the first time since the Red Sox swept a three-game interleague series in 2007.WELCOME BACKPeavy joined the Red Sox in a deadline deal in 2013 and was traded about a year later. His short stay in Boston was memorable and the Boston fans welcomed him back with a warm reception early.I love Fenway Park and getting a chance to come back here as a visitor, Peavy said. Tonight was different because youre in compete mode and youre trying to find a way to win. But I certainly appreciate the fan response. From the time I walked out of the dugout, it was positive.KOJI CONCERNSCloser Koji Uehara came in to pitch the ninth even though it was not a save situation and left after facing just one batter. Uehara was pulled after feeling a strain in his right pectoral muscle and manager John Farrell said the Red Sox werent taking any chances.Uehara was to be evaluated Wednesday.I cant tell you at this time how much time Koji is going to miss, Farrell said.TRAINERS ROOMGiants: OF Hunter Pence (strained left hamstring) had a couple of days off during a rehab assignment with Triple-A Sacramento.

Orlando Pace Jersey . -- Patrick Reed got an early start in golf. After 40 years helping some of the greatest gymnasts of all time soar to Olympic gold -- from Nadia Comaneci to Mary Lou Retton to Nastia Liukin -- Martha Karolyi is ready to say goodbye. The U.S. womens national team coordinator is retiring after the 2016 Games.The five-woman group Karolyi is bringing to Rio de Janeiro -- Simone Biles, Gabby Douglas, Aly Raisman, Madison Kocian and Laurie Hernandez -- has the perfect going away present in mind: Gold. Lots and lots of gold. Maybe all six available, something thats never been done by one country in a single Olympiad.Its a testament to the empire Karolyi has built since taking over the program in 2001 that its not merely just hype but entirely plausible, a luxury afforded when you have the three-time reigning world champion (Biles), the defending Olympic champion (Douglas), a three-time Olympic medalist (Raisman) and the reigning uneven bars world champion (Kocian) on the roster.The gap between the U.S. and the rest of the world has grown since the Fierce Five rolled to the team gold four years ago. The chance of anyone overcoming it is akin to the odds of Michael Jordan and the original Dream Team falling in Barcelona in 1992. No one came close back then. If the Americans do what theyve done at every major international event since 2011, Karolyis final meet will be more of an extended victory lap.Some things to watch for as the rest of the world looks for a pony-tailed version of The Miracle On Ice in search of an upset:THE SIMONE SHOWThe 19-year-old Biles has spent the last three years pushing the boundaries of her sport while putting together a winning streak that is three years and counting, with no apparent end in sight. Shes won 14 world championship medals (10 of them gold) since 2013 and is poised to become the fourth straight American to win the Olympic all-around gold. The Spring, Texas, native is a mix of athleticism and daring. Her Amanar vault is the closest gymnastics gets to perfection these days, and theres a real chance she could win up to five medals on her own: team, all-around, vault, floor exercise and balance beam.ENCORE PART 1Douglas is attempting to become the first reigning all-around champion to repeat in nearly 50 years. While topping Biles seems unlikely, the 20-year-old Douglas could follow in the footsteps of Comaneci, who won the all-around in Montreal in 1976 and earned silver in Moscow in 1980. Douglas path back to the Olympics has been bumpy of late. Though she was runner-up to Biles at the 2015 world championships and capturred the American Cup in March, she struggled at times during the selection process and parted with coach Kittia Carpenter in early July.ddddddddddddENCORE PART 2Raisman was the oldest member of the Fierce Five in London while winning three medals, including gold on floor exercise. The 22-year-old (nicknamed Grandma by some of her younger teammates) heads to Rio as arguably the best gymnast on the planet not named Biles. Raisman was second to Biles at both the U.S. championships and the Olympic Trials. She credited longtime coach Mihai Brestyan and her commitment to doing 8 million routines as the key to her resurgence at a time when some American stars are well into retirement.MISSING IN ACTIONRomania, which has finished on the podium in every Olympics since 1976, failed to qualify for the team competition after struggling at the 2015 world championships last fall and slumping at the end of the Rio Test Event in April. An injury to star Larisa Lordache didnt help. The Romanians will be represented by just one gymnast, 28-year-old Catalina Ponor, who will be making her fourth Olympic appearance and serve as her countrys flag bearer during opening ceremonies.THE BRITISH ARE COMINGWhile longtime powers like Romania and Russia have slipped in recent years, Great Britains program has been on the rise. The Brits finished third in the team competition at worlds last fall, the first ever team medal at the world championships in the programs history. The core of that group: sisters Becky and Ellie Downie, Claudia Fragapane, Amy Tinkler and Ruby Harrold, will try to take an even greater step in Rio.7th HEAVENOksana Chusovitina of Uzbekistan competed in her first Olympics before most of the women she will be competing against in Brazil were born. The 41-year-old will be the oldest female gymnast in Olympic history when she appears in her seventh games. Her best chance to medal will come on vault, an event she won silver on in Beijing eight years ago.Its a pity there are no points for age, Chusovitina said.BABY SHAKIRAThe 16-year-old Hernandez is the youngest member of Team USA, yet shes hardly intimidated by the stage. Her charismatic performance on floor exercise -- where she struts to the music with the attitude of a supermodel on the runway -- earned her the nickname Baby Shakira as a junior. Hernandez calls her gymnastics sassy, though she combines with a skill level that few can match. ' ' '
