Classic rock-solid: Rosters roll out at 6 ET

The baseball season is coming. So is the world.

America's Pastime has never been more popular all over the globe, and after four years of anticipation, the World Baseball Classic is back. As a delectable appetizer for the Major League feast that starts less than a month later, a spectacular 16-nation tournament, the fourth of its kind, is set to spring back into action in March in various locations in the United States and overseas.

First comes a tasty hors d'oeuvre: The star-stacked final rosters for the participating countries' teams are being revealed tonight at 6 p.m. ET on MLB Network and simulcast on MLB.com.

World Baseball Classic tickets

Soon enough, all the boxes for must-see hardball will be checked. Major League players, who have been gearing up at Spring Training, will be primed for competition with the added incentive of playing for countries full of proud fans. Fired-up crowds in the U.S., Japan, South Korea and Mexico will cheer on their favorite players as the tournament gets whittled down from four first-round pool-play sites to the eventual championship round at Dodger Stadium from March 20-22.

Rules announced for WBC 17

Team USA is shaping up to be the deepest American squad since the inaugural Classic in 2006, with manager Jim Leyland calling the shots.

"It's a nice opportunity for me," Leyland said. "But this is not a party. We want to win. I can't imagine what that would feel like. I'd love to find out."

The Americans will need to be great to do it, because they still have not won a World Baseball Classic. Japan took the '06 and '09 titles, and the Dominican Republic won the '13 installment in part because of the brilliant tournament by Classic MVP Robinson Cano, the Seattle Mariners second baseman who will be back on the field as his team attempts to defend its crown.

Players to watch on Team Japan

That will be a tougher task than ever, though.

In addition to the always-tough United States and Japan teams, the D.R. will be challenged by Puerto Rico, Venezuela, Mexico, Cuba, South Korea, the Netherlands, Australia, Canada, Chinese Taipei, Italy, Colombia, Israel and China.

Players to watch for Team Cuba

Here's how it will work: From March 6-12, there will be four first-round sites hosting pool play, with four teams apiece playing in those venues in a round-robin format, with two teams emerging from each site to compete in the eight-team second round.

Pool A, which will be contested in Gocheok Sky Dome in Seoul, South Korea, will feature the host team, plus the Netherlands, Chinese Taipei and Israel.

The Netherlands team is expected to feature big leaguers Kenley Jansen, Xander Bogaerts, Andrelton Simmons, Didi Gregorius and Jonathan Schoop, among others. Chinese Taipei will be headed by veteran pitcher and former Major Leaguer Chien-Ming Wang.

Fourth time to shine in Classic

Pool B, which will be played at the Tokyo Dome, will feature host Japan, with Astros outfielder Norichika Aoki on the roster, plus Cuba, Australia and China.

Pool C will be set in Marlins Park in Miami and will feature host Team USA in addition to the Dominican Republic, Canada and Colombia.

This pool is particularly loaded with Major League talent. The American team's expected participants include Paul Goldschmidt, Adam Jones, Nolan Arenado, Giancarlo Stanton, Andrew McCutchen, Buster Posey, Andrew Miller, Daniel Murphy, and American League Rookie of the Year Michael Fulmer.

The defending champions should have Cano, plus Manny Machado, Nelson Cruz, Adrian Beltre, Jose Bautista, Johnny Cueto, Starling Marte, Hanley Ramirez and Dellin Betances to contribute to a sterling Dominican roster.

"We have the offensive weapons and the starting pitching," Dominican Republic manager Moises Alou said. "Hopefully, we can put together the best bullpen."

Team Dominican ready for Classic

Canada should have the services of Freddie Freeman, John Axford, Justin Morneau and returning former big leaguers Eric Gagne and Ryan Dempster. And Colombia has a few big league stars expected to play, too, with Julio Teheran and Jose Quintana on initial rosters.

Pool D, at Estadio Jarros de Jalisco in Jalisco, Mexico, will feature host Mexico, plus Puerto Rico, Venezuela and Italy.

Team Mexico will be strengthened by scheduled participants such as Adrian Gonzalez, Marco Estrada, Khris Davis, Julio Urias and Yovani Gallardo.

Molina ready for fourth Classic

Puerto Rico's team should include veteran stars such as Yadier Molina and Carlos Beltran, but also two young players who recently starred in the World Series: Cubs second baseman Javier Baez and Indians shortstop Francisco Lindor.

"I'm very excited," Lindor said. "I can't wait. I can't wait to wear my Puerto Rican jersey. I'm proud of my country. I want to represent it everywhere I go. That's the reason I play -- for Puerto Rico, for Cleveland and for my family."

Venezuela is another team to fear, with big league royalty such as Miguel Cabrera, Felix Hernandez, Victor Martinez, Jose Altuve and Carlos Gonzalez expected, among others.

Venezuela's defensive alignment

The second round is slated for March 12-19, with Pool A and B winners and runners-up meeting in another round-robin format in Tokyo, while the teams that emerge from Pools C and D will match up at Petco Park in San Diego.

The four teams that emerge from the second round will head to Dodger Stadium in Los Angeles for the semifinals on March 20-21, and the championship game on March 22.
