NL Championship Favorites

Odds as of Oct. 22, 2023, at FanDuel Sportsbook.

• Oct. 12: The Philadelphia Phillies have opened as -155 favorites over the Arizona Diamondbacks in the 2023 NLCS. This marks the third straight series the still-undefeated D-Backs have entered as the underdog.
• Oct. 4: The odds heading into the NLDS favor the Braves (+160) over the Dodgers (+195), Phillies (+330), and longshot Diamondbacks (+550).
• August 9: The Phillies (+986) and Giants (+1271) are now third and fourth, respectively, in the NL Pennant odds, trailing the Braves (+141) and Dodgers (+200) by a massive margin.
• July 2: There is a massive gap in the NL Pennant odds between the two favorites (Braves at +154 and Dodgers at +250) and the rest of the field. The Diamondbacks and Giants are tied for third-favorite at +1143.
• June 12: The Diamondbacks, who own a 3.5-game lead on the Dodgers in the NL West, are still outside the top five at +1357 on average. But that’s still a vast improvement from their preseason odds of roughly +5500.
• May 29: The gap between the Braves (+216), Dodgers (+226) and the rest of the NL field has widened considerably. The third-favorite Mets are way back at +821.
• Apr. 18: Atlanta (+291) has the best record in the NL after three weeks and now sits atop the NL Pennant odds, with the Dodgers (+360) a close second.
• Dec. 12, 2022: The Dodgers are favored out of the gate in the NL Pennant odds, with the reigning NL Champs, Philadelphia, back in fifth.
