After four tense, drama-filled games, the Astros and Dodgers are even in the World Series.
Following a pitching duel between starters Alex Wood and Charlie Morton in Game 4 on Saturday, Los Angeles broke a 1-1 tie with a five-run ninth inning and prevailed, 6-2.

With the Series knotted at two games apiece, a Game 6 on Tuesday back at Dodger Stadium is guaranteed. But first, the table is set for a momentous Game 5 on Sunday night in Houston. Consider these facts: 
• Since both League Championship Series expanded to a best-of-seven format in 1985, there have been 28 LCS or World Series tied at 2-2. The winner of Game 5 has gone on to take the series in 18 of those (64.3 percent).
• A victory for the Dodgers on Sunday would be especially meaningful, given the 2-3-2 format. In best-of-seven series since 1985 when the road team wins Game 5 to grab a 3-2 advantage, it has gone on to win nine out of 10 times, with the benefit of playing at home for Game 6 and, if necessary, a winner-take-all Game 7.
Since the 1991 Pirates fell to the Braves in the National League Championship Series, the past eight teams in that situation have gone on to victory, including last year's Cubs in the NLCS against the Dodgers.
• Should Houston bounce back to win Game 5, it still would have to finish its championship run on the road, and that's no sure thing. In best-of-seven series since 1985, clubs jumping ahead three games to two at home have merely broken even at 9-9.
The Astros know these circumstances well, having overcome a 3-2 deficit against the Yankees in the ALCS by winning the final two games at Minute Maid Park. Most recently in the World Series, the 2011 Rangers dropped Games 6 and 7 in St. Louis.
• While both teams now have won on the other's home field in this series, the Dodgers are 5-1 at home this postseason, while the Astros are 7-1. Houston fell shy of becoming the first team to go 8-0 at home in a postseason, but in Game 5, it still could join the 2002 Angels as the only clubs to go 8-1.
But before looking ahead to Game 5, here's a look back at some notable facts and figures from Game 4:
Morton, Wood valiant despite no decisions
• Morton (four baserunners allowed) and Wood (three) became the first pair of competing starters to each allow four or fewer baserunners in the same World Series game.

• Game 4 was just the third World Series game to feature just one combined hit between the two competing teams through the first five innings. The most recent was Don Larsen's perfect game in the 1956 World Series, preceded by Game 4 of the 1906 Fall Classic, in which the Cubs eventually beat the crosstown White Sox, 1-0.
• Thanks largely to the efforts of the two starting pitchers, Game 4 marked the first World Series game to be tied with a score of either 0-0 or 1-1 entering the ninth inning since the legendary pitching duel between Jack Morris and John Smoltz in Game 7 of the 1991 Fall Classic.
• Wood carried a no-hitter into the sixth inning before Astros center fielder George Springer clubbed a two-out, solo home run to end both Wood's bid for history and his night on the mound. Wood's no-hit bid was the longest in a World Series game since Mets pitcher Jerry Koosman kept the Orioles hitless through the first six innings of Game 2 of the 1969 Fall Classic.

• Through the Dodgers' long and storied history -- especially when it comes to pitchers -- Wood's 5 2/3 innings marked the longest World Series no-hit bid. Saturday marked Los Angeles' 109th World Series contest.
• Wood is the ninth pitcher to start a World Series game and go at least 5 2/3 innings while allowing no more than one hit. The most recent was David Cone, who threw seven one-hit innings for the Yankees in Game 2 of the 1999 World Series.

Unfortunately, Wood joins Yankees pitcher Bill Bevens as the only pitchers in that group of nine to not be credited with a victory. Bevens lost Game 4 of the 1947 World Series despite allowing only one hit over 8 2/3 innings -- thanks in large part to his 10 walks in that contest.
• When Wood took the mound for his Game 4 start, he became the 12th and final pitcher on the Dodgers' roster to make an appearance in this World Series. That tied the 2011 Cardinals and '14 Giants for the most pitchers used in a single Fall Classic by any team.

Springer snaps no-no in style
• Springer became the first player in World Series history to break up a no-hit bid with a home run in the sixth inning or later.
• Springer, who also smacked the go-ahead two-run shot in the 11th inning of Game 2, became the first player to homer multiple times in this Series, although he later was joined by teammate Alex Bregman and Los Angeles' Joc Pederson. The first 12 big flies had come off the bats of 12 different players, leaving the Astros and Dodgers one shy of matching the all-time record for most players to go deep in a single World Series (13 in 1953).

• Including his homer, which had a 100.1-mph exit velocity, Springer smacked three more batted balls Saturday that reached Statcast™'s 95-mph baseline for "hard" contact. After going 0-for-4 with four strikeouts in Game 1, he now has 11 hard-hit balls in the Series. No other player on either team has more than seven.
Dodgers wake up late
• Cody Bellinger's opposite-field double, which ignited a seventh-inning rally for Los Angeles, snapped his 0-for-13 streak -- with eight strikeouts -- to begin the World Series.
• John Forsythe's game-tying single that scored Bellinger in the seventh was only the Dodgers' second hit with runners in scoring position after beginning the World Series 1-for-17 in those situations.

• Bellinger's second double brought home Corey Seager to give L.A. a 2-1 lead in the ninth and made him the fifth Dodgers player to record a go-ahead hit in the ninth inning or later of a World Series game. He joined Kirk Gibson (his famous walk-off home run in 1988), Jackie Robinson ('56), Duke Snider ('52) and Cookie Lavagetto ('47).
• Bellinger (22 years, 107 days) is the youngest player to double twice in a World Series game and the fifth youngest to have multiple extra-base hits of any kind. The last player younger than him to accomplish that feat was the Braves' Andruw Jones, who at age 19 homered twice in Game 1 of the 1996 Fall Classic.

• Bregman followed Pederson with a solo homer in the bottom of the ninth inning, marking the seventh and eighth homers hit by these two teams in the ninth or later during this World Series. There had been only 87 homers hit in the ninth or later over the previous 112 editions of the Fall Classic prior to 2017, and the previous tally for most homers hit so late in a single World Series was six (five by the Yankees and one by the Cardinals) in the 1964 Series.
