David Ortiz

Where to start? It’s his last go before he hangs it up, he’s been one of the best hitters in baseball this season and has an unbelievable knack for stepping up in the clutch to put the Red Sox on his back. Another title run would be a storybook ending.

Clayton Kershaw

He’s the best pitcher in baseball, but has had his struggles in the post-season, where he has a career 4.59 earned run average. Can the LA Dodgers pitcher finally exorcise his playoff demons, or will he continue to falter when it matters most?

Jake Arrieta

There was no pitcher better to start the regular season as he won his first nine decisions with a 1.72 earned run average. But in his past 16 starts, his ERA ballooned to 4.44 and he looked far from the ace the Cubs need him to be.

Trea Turner

Despite playing less than half the season in the majors, the rookie lit the big leagues on fire with a .342 batting average, 13 home runs and 33 stolen bases. He’s both incredibly fun to watch and crucial to the Nationals’ hopes.
