The Houston Astros' eight-time All-Star second baseman Jose Altuve will be out of action for at least two months following surgery on his fractured right thumb.

Altuve sustained the injury playing for Venezuela in the World Baseball Classic last Saturday after being struck on the thumb from a pitch by the United States' Daniel Bard.

The Astros confirmed in a statement that the second baseman had undergone surgery and subsequently will not resume baseball activities at least two months.

"Altuve will remain in Houston since Spring Training is in its final week," the Astros statement said. "The Astros ballclub is set to fly to Houston following their Florida Spring Training game on Sunday in West Palm Beach."

The 2023 MLB season commences next Thursday, with the Astros opening their campaign against the Chicago White Sox.

Altuve was a key part of Houston's 2022 World Series-winning team, hitting .300 with 28 home runs, 39 doubles, 18 steals and 103 runs while earning his sixth Silver Slugger Award and finishing fifth in AL MVP voting.

The 32-year-old won the 2017 AL MVP – the same year he helped the Astros win the franchise’s first World Series championship.

Among active players, Altuve ranks seventh in hits (1,935), eighth in doubles (379) and 12th in runs (986).

He was the second MLB All-Star to suffer a serious injury at the World Baseball Classic after New York Mets closer Edwin Diaz tore his patellar tendon, ruling him out for the entire season.

Shohei Ohtani was described as a "unicorn to the sport" by United States manager Mark DeRosa after he led Japan to victory in the World Baseball Classic final.

Ohtani struck out Los Angeles Angels team-mate Mike Trout to seal a 3-2 victory in a thrilling conclusion in Miami on Tuesday.

Named the tournament's MVP, Ohtani ticked off a list of achievements during the game that had only ever previously been matched in an MLB or WBC game by the legendary Babe Ruth in October 1921.

The 28-year-old started in the batting lineup, drew a walk, got a hit, came on to pitch in relief, struck out a batter and was the finishing pitcher.

"What he's doing in the game is what probably 90 per cent of the guys in that clubhouse did in Little League or in youth tournaments, and he's able to pull it off on the biggest stages," DeRosa said. 

"He is a unicorn to the sport. I think other guys will try it, but I don't think they're going to do it to his level.

"What blows me away on this stage is the fact that no moment is too big for him. He did not seem rattled by walking Jeff McNeil on a close pitch, not rattled that three MVPs were coming up to bat."

Ohtani himself was happy to accomplish one of his career goals by winning the tournament, and believed the victory over the USA was also proof that Japan can get the better of anyone.

"In my baseball life, [winning the World Baseball Classic was] one of the things that I wanted to achieve," Ohtani said. "Today I was able to achieve one of the goals.

"Of course, I happened to get the MVP, but this really proves that Japanese baseball can beat any team in the world."

MLB Opening Day is still over a week away but several of baseball's biggest names will be in action on Tuesday – and Shohei Ohtani cannot wait.

The final of the World Baseball Classic will pit Ohtani's Japan against the might of defending champions the United States.

With Ohtani planning to hit and pitch in relief as he ramps up his preparations for the new season, all eyes will be on his potential matchup with Los Angeles Angels team-mate Mike Trout, the Team USA captain.

"It's not only Mike Trout, but one through nine in that order is filled with superstars, household names," Ohtani said.

"I'm just excited to face that lineup. It's a great thing for Japanese baseball."

Ohtani was speaking after Japan's dramatic 6-5 comeback win over Mexico that booked their spot in the final.

In an apparent nod to the Angels' eight-year absence from the MLB playoffs – spanning his entire career – Ohtani said: "It's been a while since I've played in a win-or-lose game, in a playoff atmosphere."

Munetaka Murakami, a Japanese Triple Crown winner last year, clinched Japan's victory with a walk-off double at the bottom of the ninth.

"It was the best, epic," said Boston Red Sox outfielder Masataka Yoshida, while Mexico manager Benji Gil graciously added: "Japan advances, but the world of baseball won tonight."

That is still not enough for Ohtani, though, as the two-way superstar said: "Obviously, it's a big accomplishment to get to the championship series.

"But there's a big difference from being in first and second, so I'm going to do all I can to get that first place."

Houston Astros All-Star second baseman Jose Altuve suffered a fractured right thumb at the World Baseball Classic and will require surgery, sidelining him indefinitely.

Astros general manager Dana Brown revealed the severity of the injury on Sunday, a day after Altuve was hit by a pitch from reliever Daniel Bard in the fifth inning of Venezuela’s 9-7 quarter-final loss to the United States.

The Astros said he will undergo surgery in the coming days, and they will then determine a prognosis for him.

There is no official timeline for when he will return, but it has been reported that similar injuries have sidelined players for eight-to-10 weeks.

A major part of Houston’s dominance over the last half-dozen years, the 32-year-old Altuve is coming off his eighth All-Star season.

In helping the Astros win the 2022 World Series, Altuve hit .300 with 28 home runs, 39 doubles, 18 steals and 103 runs while earning his sixth Silver Slugger Award and finishing fifth in AL MVP voting.

He won the 2017 AL MVP – the same year he helped the Astros win the franchise’s first World Series championship.

Among active players, Altuve ranks seventh in hits (1,935), eighth in doubles (379) and 12th in runs (986).

He is the second MLB All-Star to suffer a serious injury at the World Baseball Classic after elite New York Mets closer Edwin Diaz tore his patellar tendon, ruling him out for the entire season. 

New York Mets pitcher Edwin Diaz is expected to miss the entire MLB season after suffering a serious knee injury while celebrating a Puerto Rico win in the World Baseball Classic.

Diaz left the field in a wheelchair after injuring his right knee while celebrating Wednesday's win over the Dominican Republic, with his team-mates visibly upset by the incident.

On Thursday, the Mets revealed Diaz – who penned a five-year, $102million contract with the team in the offseason – had undergone surgery after sustaining a complete patellar tendon tear.

"Edwin Diaz underwent successful repair of the patellar tendon in his right knee today," read an update from the team. "He is expected to begin a formal rehab program in about a week."

Earlier on Thursday, Mets general manager Billy Eppler suggested the closer – widely considered to be the best in the game – could be sidelined for around eight months, a timeline which would rule him out for the entire 2023 season.

Eppler noted some athletes have returned from similar injuries within a six-month timeframe, but added such cases were "more the exception than the rule".

Diaz took to social media to update his fans after the surgery, writing on Twitter: "To all my beloved fans, especially the Mets fans, I want to let you know that I am doing well and healing. 

"I feel blessed and grateful for your support with messages and prayers, thank you very much!  I can't wait to see you guys in NY again and play those trumpets."

Celebrations for Puerto Rico at the World Baseball Classic turned sour when pitcher Edwin Diaz hurt his knee after their victory against the Dominican Republic.

The New York Mets closer – widely considered to be the best in the game – eliminated the favourites for the competition as he struck out Teoscar Hernandez to complete a 5-2 victory.

In the ensuing celebrations, the players were jumping in a huddle before stopping once it became apparent that Diaz was injured.

His brother, Cincinnati Reds reliever Alexis Diaz, was in tears as medics attended to him, helping the 28-year-old from the field.

According to ESPN, the 28-year-old will undergo an MRI on Thursday, with sources fearing "the injury could keep Díaz out for a significant period".

"I didn't see it right away," Puerto Rico manager Yadier Molina said. "I was hugging our coaches in the dugout, and when we looked up, Edwin was on the ground.

"I didn't know. I didn't know how to act, I didn't know what to say. It caught me by surprise. It sucks. When you see a guy that works so hard like Edwin, when you see him on the ground like that, it's just sad."

Center fielder Enrique Hernandez added: "It wasn't pretty much until we got to the infield dirt that we realised something had gone wrong.

"At the moment we didn't know who it was. When we got there, that's when we realised who it was. Obviously, aside from being the best closer in the game right now, and being a huge part of this team, [Diaz] is one of the glue guys in that clubhouse."

The Arizona Diamondbacks and top prospect Corbin Carroll have agreed to an eight-year contract extension, according to multiple reports.

The 22-year-old outfielder signed for a base compensation of $111million, with a team option and escalators that could raise the total value of the deal over $134m.

According to MLB.com, Carroll's compensation is the most ever given to a U.S.-based player with fewer than 100 days of major league service time.

The previous record of $70m had been set by the Atlanta Braves' Michael Harris, who went on to be named the 2022 NL Rookie of the Year.

The deal locks Carroll up for all of his arbitration-eligible seasons, plus at least his first two free agency seasons.

Arizona drafted Carroll in the first round of the 2019 draft, and the left-handed center fielder has remained among the highest-ranked prospects in the organisation ever since.

Carroll made his major league debut last season, batting .260 with an .830 OPS in 115 plate appearances. In 32 games he had 27 hits, 15 for extra bases.

Earlier this offseason, MLB.com ranked the speedy outfielder as the No. 2 prospect in baseball, behind Baltimore Orioles infielder Gunnar Henderson.

The New York Yankees will be without left-handed starter and prized free agent acquisition Carlos Rodon to start the season in yet another blow to the Yankees’ pitching staff before the year has even begun.

Rodon, who received a $162 million contract to join New York this off-season, is suffering from a left forearm strain and will be on the injured list when the Yankees open the 2023 campaign in three weeks.

Rodon underwent an MRI on Wednesday, which revealed an injury similar to one that the two-time All-Star dealt with last season while with the San Francisco Giants.

“The finding was something, but not significant or serious,” Yankees general manager Brian Cashman told reporters on Thursday. “Obviously, trying to pitch through stuff is not a good thing, especially this time of year.

“If this was in-season - pennant race, late in the game - he's still probably up and running. He had this last May with the Giants, and he didn't miss any time with it.”

While Rodon was able to play through the injury last season, he was 1-4 in his five May starts with a 5.67 ERA – easily the worst stretch of his 14-8 campaign.

Rodon reiterated to reporters on Thursday that he could play through the injury if it had occurred at a more crucial time of the season, but the Yankees would not put a timetable on the lefty making his debut in pinstripes.

Cashman said that Rodon will take at least a week recovering on a no-throw program before ramping him up.  

“You just have to prevent looking at the calendar and force-feeding it and speeding the process up because you feel the outside pressure of it's a new organisation, fan base, stuff like that,” Cashman said. “[Rodon] understands that. He's a pro. But like anything else, it's the human nature of, 'I want to get out there and pitch.'”

Cashman also announced that relievers Lou Trivino and Tommy Kahnle would also begin the season on the injured list. The Yankees’ rotation is already missing last year’s mid-season acquisition, Frankie Montas, who underwent shoulder surgery in February.

Domingo German, Clarke Schmidt and Deivi Garcia are among the candidates to open the 2023 season in the Yankees’ starting rotation that will feature Gerrit Cole, Nestor Cortes and Luis Severino.

The Yankees open the season at home against the Giants on March 30.
