2. Los Angeles Dodgers

WATCH: Verducci's preview

The Dodgers have the best pitcher in the game and some high-caliber hitters, but will Los Angeles' shaky bullpen be the undoing of its World Series hopes once again?

The Mariners are ready to take the AL West crown for the first time in 14 years behind the power arm of Felix Hernandez and a strong lineup.

MVP Mike Trout leads an Angels team that had the most wins in MLB last season but has a razor-thin margin for error in 2015.

WATCH: Verducci's preview

The Indians' balanced roster and breakout stars in Corey Kluber and Michael Brantley have Cleveland looking like a real title contender.

Worst to first redux? The Red Sox look primed to bounce back from last year's 91-loss debacle and grab the AL East crown.

WATCH: Verducci's preview

With a balanced lineup, strong rotation and innovative coaching staff, this could be the year the Pirates break through in the NL Central.

Can Detroit run its streak of AL Central titles to five straight, or will the Tigers' unprecedented span of success finally come to an end?

Led by MVP favorite Giancarlo Stanton and an impressive young core, the Marlins have the look of a real contender.

Image placeholder title

11. San Francisco Giants

WATCH: Verducci's preview

The defending champs return mostly intact for 2015, but the Giants will find the road to a repeat and a fourth World Series title in six years to be a difficult one.

Image placeholder title

12. Toronto Blue Jays

WATCH: Verducci's preview

Thanks to a rebuilt lineup and some young power arms in the rotation, Toronto is poised to end the majors' longest postseason drought.

Image placeholder title

13. Chicago White Sox

WATCH: Verducci's preview

The White Sox won the winter, but turning those off-season accolades into on-field success will be a whole new challenge for Chicago.

Image placeholder title

14. San Diego Padres

WATCH: Verducci's preview

Rebuilt and reloaded for contention, the Padres bring a brand new offense and bolstered rotation into a season with high expectations.

Image placeholder title

15. Baltimore Orioles

WATCH: Verducci's preview

Last year's surprising AL East champions are out to prove that 2014 was no fluke, but the odds are once again against them.

Image placeholder title

16. Chicago Cubs

WATCH: Verducci's preview

Armed with a new manager, a top-of-the-rotation starter and a core of super prospects, the Cubs are on the verge of true contention.

Image placeholder title

17. New York Mets

WATCH: Verducci's preview

Matt Harvey is back to lead a young and talented Mets rotation that will have to overcome a less-than-inspiring offense.

Image placeholder title

18. Oakland Athletics

WATCH: Verducci's preview

Overhauled once more, the A's will try to stay in the playoff hunt despite a roster that was weakened by an off-season teardown.

Image placeholder title

19. Kansas City Royals

WATCH: Verducci's preview

Last year was a dream come true for the Royals, but expect some regression from 2014's unexpected American League champions.

Image placeholder title

20. New York Yankees

WATCH: Verducci's preview

The Yankees could be dangerous, but their old lineup and shaky rotation make them as likely a bet to finish last in the division as to make the playoffs.

Image placeholder title

21. Tampa Bay Rays

WATCH: Verducci's preview

There are plenty of new faces on the Rays, but not for the best, as all the off-season change and turnover has Tampa Bay headed for a bridge year.

Image placeholder title

22. Milwaukee Brewers

WATCH: Verducci's preview

With little starting pitching depth and questions in the lineup, the Brewers have only an outside shot at contending in the loaded NL Central.

Image placeholder title

23. Cincinnati Reds

WATCH: Verducci's preview

The Reds need their offense to be flawless to make up for a rotation that, aside from Johnny Cueto, lacks impact, stability and upside.

Image placeholder title

24. Texas Rangers

WATCH: Verducci's preview

Last year, injuries decimated the Rangers and ruined their hopes, but unfortunately for Texas, 2015 is already off to a similar start.

Image placeholder title

25. Houston Astros

WATCH: Verducci's preview

Houston's offense looks powerful, but the Astros' free-swinging ways and thin rotation will make their climb to contention a tough one.

Image placeholder title

26. Atlanta Braves

WATCH: Verducci's preview

Expect a rough year, especially on offense, for a Braves team that dealt away most of its roster and has its eye on the 2016 season and beyond.

Image placeholder title

27. Colorado Rockies

WATCH: Verducci's preview

The season hinges on the health of Troy Tulowitzki and Carlos Gonzalez, but will they be enough to lift the Rockies out of their losing ways?

Image placeholder title

28. Minnesota Twins

WATCH: Verducci's preview

Last year, the Twins were sunk by the worst rotation in baseball. Can this year's revamped Minnesota squad turn that struggle around?

Image placeholder title

29. Arizona Diamondbacks

WATCH: Verducci's preview

Led by Cuban free-agent signing Yasmany Tomas, Arizona has an all-new look for 2015, but the Diamondbacks have more questions than answers.

Image placeholder title

30. Philadelphia phillies

WATCH: Verducci's preview

The much-needed rebuild has finally begun in Philadelphia, and the result is going to be a painful and long year for Phillies fans.
