Stephen Strasburg's sinker may still be a work in progress. His other pitches seem to be rounding into shape quite nicely.After giving up back-to-back singles – both on sinkers – to start the game, the Washington ace struck out six over three innings Thursday night in a 4-all tie with the New York Mets. The game was called after 10 innings.Strasburg, expected to be the Nationals' opening day starter, already has an overpowering fastball, a wicked curve and a changeup that just doesn't seem fair. A big goal this spring is getting a better feel for his sinker, but he admitted he's still struggling with it.“I need to get over the idea of throwing it harder will make it better,” he said. “I feel like I'm just kind of throwing through the sink and it's kind of flattening out. I want to throw it a little bit slower, let it move a little bit more and I'll get better results.”The 24-year-old right-hander is also working on calming himself down and not getting too pumped up in the first inning, which causes him to rush through his delivery. He struggled with that a little bit in his initial spring outing – he gave up a single and home run to the first two Mets batters – but made the adjustment much quicker Thursday night.“Being so early, I don't feel like I've had enough mound time for it to just click, and not really think about it,” Strasburg said. “I'm still trying to feel it out a little bit. The good thing is I felt good when I came out. That's the bottom line.”While Strasburg gave up a run on three hits while also walking two, the Mets got a look at one of their bright, young arms in the form of 22-year-old right-hander Rafael Montero.Montero was the team's minor league pitcher of the year last season. He made his first spring start and threw two innings, giving up three hits – all doubles – and one run.Maurer, wife expecting twins, of courseAs news spread that Joe Mauer and his wife are expecting twins in August, the All-Star catcher had two hits with an RBI, a walk and two runs scored to lead the Minnesota Twins over the Baltimore Orioles 7-1 on Thursday.Mauer said he and his family have known for a while about his impending fatherhood. He used the word “blessing” several times in describing his emotions to the media.Mauer said the twins are expected at the end of August. By then, Mauer's team could be much improved from last season's 66-96 finish should the Twins extend their hot spring training starts into the regular season.First baseman Justin Morneau, who rarely played on back-to-back days last spring while recovering from post-concussion symptoms, played for the fifth consecutive game Thursday and went 2 for 3 with a two-run double. Morneau plans on representing Canada in the World Baseball Classic.Cano receives offer The Record of New Jersey Robinson Cano has received a “significant” offer from the Yankees, according to general manager Brian Cashman, who revealed the important early effort to keep his All-Star second baseman from hitting the free agent market this fall.“We've made an offer to him. We've made a significant offer to him,” Cashman said on Thursday, though he refused to further elaborate.Briefly• World Baseball Classic: South Korea is seen as the favorite of the four-team Group B, which starts play Saturday (10:30 p.m. tonight CST) in the opening round of the World Baseball Classic at Taipei, Taiwan.

Getting stronger and stronger.” The 43-year old pitched one inning against Yankees' minor leaguers. He also fielded and covered first base.Rivera pitched in nine games last year, his season ending when he tore the anterior cruciate ligament in his right knee while tracking down a fly ball during batting practice in Kansas City on May 3. He had surgery on June 12.Yankees ace CC Sabathia, likely to start the season opener against Boston on April 1, threw 46 pitches over two innings during his initial simulated game. The left-hander had offseason left elbow bone spur surgery.David Phelps allowed two hits over three scoreless innings as a New York spilt squad lost 1-0 to the Toronto Blue Jays. Phelps struck out one and walked one, and has not given up a run in five innings over two starts. He could earn a spot in the rotation to start the season if Phil Hughes remains sidelined by a bulging disk. Hughes is working out in a pool and might resume throwing in a few days.• Giants: San Francisco outfielder Andres Torres won't play for Puerto Rico in the World Baseball Classic and will be sidelined for at least a week because of a strained oblique. The Giants made the announcement Thursday, a day after he got hurt during a swing and had an MRI.

RHP Jake Westbrook bruised his left leg below the knee on a grounder hit by Casey Kotchman in the second inning. Beltran's X-rays were negative, but he said the injury was painful, and he was unsure whether it would affect his plans to play for Puerto Rico in the World Baseball Classic.• Marlins: Giancarlo Stanton had a triple, double, single and walk as Miami lost to St Louis. Last year's NL slugging champion finished February with a slugging percentage of 1.000 and is impressing new manager Redmond.• Red Sox: John Lackey retired Pittsburgh on eight pitches in the first inning of a 16-6 Boston win.

I've done my throwing and my bullpens but I have not been out there with umpires and guys in uniforms for a long time.”Garland was 1-5 with a 4.33 ERA in just nine starts for the Los Angeles Dodgers before labrum and rotator cuff surgery ended his 2011 season in July. He tried to make it back last year with Cleveland but suffered complications.“There was definitely more adrenaline going than usual,” Garland said. “I really just wanted to come out of it healthy. I felt good about my pitches and how I was throwing.”Justin Smoak collected two more hits and drove in a run for the Mariners. Alex Liddi also drove in a run as Seattle matched its longest spring win streak since 2004.Brandon Belt had two hits, including a homer, and scored both runs for the Giants, who are winless in their last five games. Brandon Crawford and Cole Gillespie also drove in runs.Garland was satisfied with a brief outing in which he allowed a hit and walked one in one inning.“To a certain extent I felt that was where I belonged,” Garland said. “I felt good about that.”Garland's impressive resume includes two 18-win seasons (2005, 2006) for the Chicago White Sox. He has won at least 12 games seven times and pitched at least 200 innings in six seasons. He has a 132-119 record with a 4.32 ERA in 330 starts.Smoak is hitting .583 this spring with six RBIs.Giants ace Matt Cain lasted three innings, giving up three runs on four hits. He walked one and struck out two.“Everything felt good,” Cain said. “I was inconsistent with my location. I was a little bit out of rhythm and I'll need to work on that.”Cain said he declined an invitation to play with Team USA because of the way the Giants' season played out last year and throwing an excess of pitches.“I just felt better in taking some time and going through spring training,” Cain said. “With the (World Baseball Classic) you had to ramp it up early. I felt I could benefit from spring training.”The Giants' – and the Cincinnati Reds' – rotation stayed healthy and each made all their starts last year. That hasn't happened since the 2005 White Sox pitching staff went through a healthy season.“You know it's rare when it hasn't been done for a while,” Cain said. “It's hard to stay healthy. Then you get five guys trying to stay together. I just want to make all my starts. If I can do that, I feel good things will happen.”NOTES: Garland allowed three runs on five hits over six innings in his last Major League appearance on June 2, 2011. … The Mariners have hit a Major League best 14 home runs. … LHP James Paxton will start Friday's game against the Texas Rangers. … Giants manager Bruce Bochy wrote a lineup that included most of his Opening Day starters, including Cain. He cited the loss of several players to the World Baseball Classic this weekend as the reason. … LHP Madison Bumgarner will make his second start of the spring for the Giants at Oakland on Friday. He will be opposed by A's RHP Jarrod Parker. … The Giants played to a tie in each of their previous three games and all six games have been decided by three runs or less.Mets LHP Feliciano OK to resume baseball activityNew York Mets reliever Pedro Feliciano has been cleared to resume baseball activity while wearing a heart monitor.Manager Terry Collins said he thinks Feliciano will have enough time in spring training to get ready for the start of the season.“He's cleared to do everything, which is a great sign,” Collins said before Thursday night's game against Washington. “Obviously, since he hasn't thrown in a while, I'm sure (pitching coach) Dan (Warthen) has a schedule to throw him a couple times to make sure it doesn't inhibit him from doing some stuff.”The 36-year-old Feliciano was with the New York Yankees for the last two seasons but didn't pitch in any games because of shoulder trouble.Feliciano visited the Minneapolis Heart Institute Clinic at Abbott Northwestern Hospital on Wednesday for tests. The exams showed he had a rare genetic condition called left ventricular noncompaction. It results from the failure of myocardial development from birth.“I am ready to return to spring training with my team,” Feliciano in a statement sent by his representatives. “I will attend my ailment that was discovered during a routine checkup and not because of pain.“I can honestly say it will not keep me up at night. I will be on top of my condition but it will not stop me from playing baseball,” he said.
