Case: Signed through 2017, Beltre is likely nearing the end of what looks to be a Hall of Fame career. Judging by his 2015 output, he still has plenty in the tank. Beltre slashed .287/.334/.453 last season with 18 homers and 83 RBIs for the Rangers and finished seventh in MVP voting. If he stays healthy, a reprise of those totals — or perhaps even better — could be in store this season. Even though Beltre has lost a step at third base, he’s still strong at the hot corner: He finished 2015 fourth in the league in Defensive WAR ().
Kershaw joined this exclusive group by putting up some ridiculous numbers as a starter. The 26-year-old Dodgers ace made 27 starts in 2014, posting a sparkling record of 21 wins and three losses. He struck out 239 hitters while only walking 31, and tallied a career-best ERA (earned run average) of , good enough to lead the National League for the fourth year in a row. He also finished off a half-dozen complete games this season, most in his career. Those 2014 statistics helped Kershaw earn the MVP selection over Miami’s Giancarlo Stanton and Pittsburgh’s Andrew McCutchen.
