A Brewers sweep of the Dodgers didn’t keep MLB fans from tuning in. NLCS Viewership gave Fox and FS1 their best LCS numbers since 2015.
What We Know: Milwaukee swept Los Angeles to win the National League pennant for the first time in franchise history. Overall, the four-game series averaged 7,533,000 viewers, the best for any LCS on any network since 2015. That’s up 77% from the 2025 ALCS through Game 4. On FS1 alone, the clincher averaged 6,135,000 viewers, the most-watched LCS Game 4 since 2018 and up 107% from last year’s ALCS Game 4. The audience peaked at 7,322,000 viewers from 11 to 11:08 p.m. ET, according to Nielsen Media Research.
What the Data Says: (via FOX Sports PR)
| Game / Metric | 2026 Viewers | 2025 Viewers | YoY Change | Network | Historical Ranking | Peak Viewership |
|---|---|---|---|---|---|---|
| NLCS Series Average (4 Games) | 7,533,000 | 4,261,000 | +77% | FOX / FS1 | Highest LCS average since 2015 | — |
| NLCS Game 4 (FS1 Only) | 6,135,000 | 2,964,000 | +107% | FS1 | Most-watched LCS Game 4 since 2018 | 7,322,000 |
What Remains Unclear: Fox didn’t say how streaming or out-of-home viewing shaped the totals, so the full picture remains unclear. Likewise, Nielsen’s 2026 methodology changes make year-over-year comparisons tricky.
What It Means: The strong ratings reinforce baseball’s value as a major television property. For FOX Sports, the year-over-year increase highlights the appeal of postseason baseball to advertisers and provides further justification for its investment in the sport. More broadly, the numbers suggest baseball can still attract substantial national audiences despite increasing competition for viewers. While Nielsen’s methodology changes complicate year-over-year comparisons, the results offer an encouraging sign for baseball’s long-term television prospects.
