* After playing 720 regular season games against each other, the Cubs and Mets are meeting in the postseason for the first time ever (Cubs lead the all-time series, 366-352-2). Going back to last season (since August 17, 2014), the Cubs have won nine straight games against the Mets, which is tied for the second-longest active winning streak by one team over another team (regular season only).
* Through five postseason games, the Cubs have already hit 12 home runs, the second most they have ever hit in a single postseason (17 in 2003). Through the Mets’ first five games this postseason, they have struck out 54 batters, the most batters they have ever struck out through the first five games of a postseason. New York struck out at least 10 batters in four of its five games against the Dodgers.
* Jon Lester will be making his eighth-career start in Game 1 of a postseason series (including 2014 Wild Card game), which is tied for the third-most Game 1 starts in MLB postseason history (includes Wild Card games). In his previous seven Game 1 starts, Lester is 3-3 (team record is 3-4) with a 2.74 ERA and a .203 opponent batting average.
* Matt Harvey got the win in his first career postseason start (Game 3 of NLDS vs. Dodgers), going five innings with seven strikeouts and just two earned runs. Since July 11, Harvey is 7-2 (14 starts) with a 2.30 ERA and a .217 opponent batting average (regular and postseason combined). At home this season, Harvey is 9-3 (18 starts) with a 2.29 ERA and a .221 opponent batting average (regular and postseason combined).
* Through his first five career postseason games, Kyle Schwarber is currently hitting .538 (7-for-13) with three home runs and five RBI. Schwarber is the first player in MLB history to be batting .500+ with three-plus home runs, and five-plus RBI through his first five career postseason games. Schwarber will be facing the Mets for the first time in his career in this series.
* In his first career postseason, Daniel Murphy has had a hit in every game and is batting .333 (7-for-21) with three home runs and five RBI. Murphy is the first Mets player to have a hit in each of his first five career postseason games since Carlos Delgado and Paul Lo Duca did so in 2006. No Mets player has ever had a hit in each of his first six career postseason games.
