The 2015 MLB season has officially begun, and every team except the St. Louis Cardinals and Chicago Cubs are currently having their Opening Day.
A-Rod returns – New York Yankees star to return and bat 7th
Craig Kimbrel Padres – San Diego Padres trade for Atlanta Braves closer
Yordano Ventura extension – Kansas City Royals sign starting pitcher to five-year, $23 million contract
The Cardinals defeated the Cubs, 3-0, in their season opener as ace Adam Wainwright pitched six shutout innings while Cubs free-agent prize Jon Lester struggled in 4.1 innings with three runs allowed.
There are 162 games in a baseball season though, so there are several months ahead for baseball teams to prove their worth as World Series contenders.
The Washington Nationals and Los Angeles Dodgers enter the 2015 season as the favorites to win the World Series, but there are many other talented teams.
Baseball is also known for being unpredictable and having teams make surprise runs, like the Kansas City Royals did last season by unexpectedly making the playoffs and reaching Game 7 in the World Series.
The San Francisco Giants also made an underdog run as they made the playoffs as a wild-card team and won their third World Series title in five years.
Here are predictions of how the divisions and playoffs will shake out and who will win the World Series.
