Record: 100-59

Run differential: +244

Best position player: Jose Ramirez — .314/.367/.577, 29 HR, 81 RBI, 16 SB

Best pitcher: Corey Kluber — 18-4, 2.27 ERA, 11.9 K/9, 0.861 WHIP

One thing to know: The Indians cemented their status as World Series frontrunners by going on an incredible 22-game winning streak, setting a new American League record in the process. Even now, they've only lost three games since August 24.

Record: 99-60

Run differential: +197

Best pitcher: Justin Verlander — 5-0, 1.06 ERA, 11.4 K/9, 0.647 WHIP

One thing to know: With six different hitters with over four Wins Above Replacement, the Astros might have the deepest lineup in MLB. They've also gotten a major assist from Verlander, their biggest trade deadline acquisition in years.

Seed: No. 1 in NL, will play the winner of the NL Wild Card game in the NLDS.

Record: 102-57

Run differential: +193

Best position player: Justin Turner — .321/.415/.530, 21 HR, 70 RBI

Best pitcher: Clayton Kershaw — 18-4, 2.21 ERA, 10.5 K/9, 0.930 WHIP

One thing to know: Regardless of how their season ends, these Dodgers have earned a permanent place in baseball lore. They were on pace to break the National League record for most wins in a season before hitting the skids and going on a 1-16 run in August and September. At least they've righted the ship since then, taking six of their last seven.

Seed: No. 2 in NL, will play the Cubs in the NLDS.

Record: 96-63

Run differential: +148

Best position player: Bryce Harper — .324/.418/.608, 29 HR, 87 RBI

Best pitcher: Max Scherzer — 16-6, 2.55 ERA, 12.0 K/9, 0.907 WHIP

One thing to know: Washington's bullpen was in shambles before the trade deadline, and general manager Mike Rizzo was aggressive in finding a solution, dealing for established relievers Sean Doolittle, Ryan Madson, and Brandon Kintzler. The three have since combined for a 2.04 ERA in Nationals colors.

Seed: No. 3 in NL, will play the Nationals in the NLDS.

Record: 90-69

Run differential: +119

Best position player: Kris Bryant — .295/.410/.539, 29 HR, 73 RBI

Best pitcher: Kyle Hendricks — 7-5, 3.03 ERA, 7.9 K/9, 1.189 WHIP

One thing to know: While this season was a relative disappointment compared to last year's 103-win campaign, the Cubs have gone 13-3 over their last 16 games, giving them reason for optimism as they return to the postseason. They'll have a chance to become the first back-to-back World Series champions since the 2000 Yankees.

Seed: No. 3 in AL, will play the Astros in the ALDS.

Record: 92-67

Run differential: +116

Best position player: Mookie Betts — .264/.342/.455, 23 HR, 101 RBI, 24 SB

Best pitcher: Chris Sale — 17-8, 2.90 ERA, 12.9 K/9, 0.970 WHIP

One thing to know: 2017 was the year of the home run, but it seems the Red Sox never got the memo. Just four of their everyday players possess a league-average OPS, and just one, rookie third baseman Rafael Devers, is more than 10% better than your typical MLB hitter.

Seed: No. 4 in NL, will play at home versus the Rockies in NL Wild Card game.

Record: 92-67

Run differential: +143

Best position player: Paul Goldschmidt — .302/.408/.572, 36 HR, 120 RBI, 18 SB

Best pitcher: Zack Greinke — 17-6, 3.18 ERA, 9.6 K/9, 1.054 WHIP

One thing to know: The Diamondbacks may have gotten the steal of the trade deadline when they sent three mediocre prospects to the Detroit Tigers in exchange for J.D. Martinez. With 29 homers in 247 plate appearances, Martinez has done nothing but rake since his arrival in the desert.

Seed: No. 4 in AL, will play at home versus the Twins in AL Wild Card game.

Record: 89-70

Run differential: +194

Best position player: Aaron Judge — .284/.421/.625, 51 HR, 112 RBI, 125 BB

Best pitcher: Luis Severino — 14-6, 2.98 ERA, 10.7 K/9, 1.040 WHIP

One thing to know: A generation ago, the Yankees were known for spending endless sums to bring in premium free agents, but this year's roster looks a lot different than those teams. Between Judge, Gary Sanchez, Starlin Castro, Didi Gregorius, and Aaron Hicks — all 27 or younger — the Bronx Bombers have a consistently dangerous lineup.

Seed: No. 5 in NL, will play at the Diamondbacks in NL Wild Card game.

Record: 86-73

Run differential: +64

Best position player: Charlie Blackmon — .328/.397/.598, 36 HR, 100 RBI, 14 SB

Best pitcher: Jon Gray — 10-4, 3.67 ERA, 9.1 K/9, 1.296

One thing to know: The Rockies survived a series of late challenges to take the National League's second Wild Card, a spot they've occupied since the first half of the season. Blackmon now owns the league record for most RBI by a leadoff hitter.

Seed: No. 5 in AL, will play at the Yankees in AL Wild Card game.

Record: 83-76

Run differential: +21

Best position player: Byron Buxton — .255/.317/.418, 16 HR, 28 SB, many highlight reel catches

Best pitcher: Ervin Santana — 16-8, 3.28 ERA, 7.1 K/9, 1.126 WHIP

One thing to know: After going 59-103 in 2016, the Twins are the first team in history to lose more than 100 games and qualify for the postseason the following year. They surely wish they still had closer Brandon Kintzler, who was traded to the Nationals in July before a late playoff push.
