AL MVP: Josh Donaldson
Donaldson and Trout are so close in Fangraphs' "dashboard" sabermetric stats. The AL is lucky to have three super close awards races this year in the MVP, ROY, and Cy Young.
The facts that Trout ended up edging Donaldson in WAR by 0.3 wins and batting average by a hair aren't enough to overcome Donaldson's leads in context dependent stats (RE24, WPA), certain traditional stats (RBI, Runs), and the MLB standings. Donaldson also has the narrative on his side since he was traded to Toronto in the offseason and he can be viewed as the single biggest reason that Toronto is finally in the playoffs again. I think Donaldson will win the AL MVP and I think it will be justified. At this rate, we might look back at Trout's 20 year career some day and wonder why he *only* won like, 7 MVP awards.
NL MVP: Bryce Harper
See the write-ups above. Nothing more for me to add here. It should be unanimous.
AL Cy Young: David Price
Price edged Keuchel in fWAR, K rate, ERA, and FIP. Kuechel had 2 more wins than price, a better xFIP, and 12 more innings. Both teams made the playoffs. This is a dead heat.
Chris Sale had the best FIP, xFIP, and K rate in the AL. He was probably the league's best full season SP in terms of talent alone. This is a three way dead heat!
I think Price's ERA crown will be significant to voters, as will the fact that he switched teams mid-season and lead a division champion team's rotation into the playoffs. I don't think Keuchel deserves any significant credit for the IP and W gap, considering part of that comes from the luxury Toronto had to skip Price's final start of the season. Unlike Spencer, I think there is some room in the Cy Young discussion for ERA and Price's gap on Sale is much larger than Arrieta or Greinke's gap on Kershaw. I think the voters will pick Price, so I'm picking Price.
Kershaw was easily the best pitcher in the NL this year. He had a FIP under 2.00 and he K'd over 300 batters! It's a crying shame that win totals and a couple of slightly fluky ERA seasons from two other very good pitchers could actually have him 3rd in Cy Young voting behind Arrieta and Greinke.
AL Manager of the Year: John Gibbons
Gibbons was exactly what the star-studded 2015 Blue Jays needed at the helm. His laid back demeanor helped the team stay cool when they hit rough patches, struggled on the mound, and found themselves at .500 after ~100 games. Then, his hands off managing style gave plenty of room for his star players to lead and ostensibly create a great clubhouse atmosphere. Throughout it all Gibbons' bullpen management was very good and his tactical decisions (like pinch running Pompey late in the season) seemed to pay off more often than not. Gibby the best.
NL Manager of the Year: Bruce Bochy
See what Spencer wrote. Alternate choice - Mike Matheny, because the Cardinals win lots of games and he is their manager.
AL Rookie of the Year: Carlos Correa
Correa came second to Lindor in fWAR. Both rookie shortstops played 99 games and succeeded offensively, but UZR likes Lindor's defense more. I don't think 99 games worth of UZR should be the deciding factor here. Carlos Correa is a destined superstar - the potential reincarnation of Alex Rodriguez. He hit more dingers, and his team made the playoffs. I love Lindor, and he's a future star as well (even if his bat isn't this good), but Correa is sexier and he's my ROY.
NL Rookie of the Year: Kris Bryant
See above. No debate.
World Series: Rangers over Cubs for no particular reason.
