Washington Nationals

As the Washington Nationals prepare to face off against the Chicago White Sox on September 27, 2025, both teams are looking to shake off disappointing seasons. The Nationals sit with a record of 65-95, while the White Sox are struggling even more at 59-101. Both teams are well out of contention, making this matchup more about pride than playoff positioning.

In their last outing, the Nationals faced the White Sox and secured a narrow victory, a much-needed boost for a team that has had its share of struggles this season. They’ll hope to build on that momentum as they return to Nationals Park for the second game of the series.

On the mound, Jake Irvin is projected to start for the Nationals. Although he has a subpar Win/Loss record of 9-13 and an ERA of 5.69, the projections suggest he may have been unlucky this year, with a lower xFIP of 4.85. Irvin is expected to pitch around 5.3 innings, allowing an average of 2.6 earned runs. He faces Sean Burke of the White Sox, who also struggles with a 4-11 record and a more favorable ERA of 4.29, but his xFIP indicates he may regress moving forward.

The Nationals’ offense, ranked 25th in the league, has been lackluster, highlighted by their 27th ranking in home runs. Contrarily, the White Sox rank even lower at 28th, making this matchup a battle of two struggling lineups. The Nationals’ best hitter has been performing well recently, boasting a .429 batting average and two home runs in the past week.

With a Game Total set at 8.5 runs and the Nationals favored at -120 on the moneyline, this matchup is expected to be tight. Washington’s modest implied team total of 4.35 runs suggests that the sportsbooks believe in their ability to capitalize on the White Sox’s weaknesses.

Chicago White Sox Insights

• Sean Burke – Over/Under 4.5 Strikeouts (-120/-110)
  Sean Burke’s 2555-rpm fastball spin rate this year is in the 97th percentile among all SPs.
  Explain: Spin rate is a key component to fastball success in generating strikeouts and preventing runs.
• Chase Meidroth – Over/Under 1.5 Total Bases (+125/-160)
  Chase Meidroth’s average exit velocity has decreased of late; his 88.2-mph seasonal EV has fallen off to 85.4-mph in the past week’s worth of games.
  Explain: Hitting the ball hard increases the chances of either a home run or the ball landing in fair territory for a hit before a fielder can get to it.
• Colson Montgomery – Over/Under 1.5 Total Bases (+100/-130)
  Colson Montgomery pulls a high percentage of his flyballs (36.6% — 93rd percentile) and will have a big advantage hitting them towards baseball’s 10th-shallowest RF fences in today’s game.
  Explain: This player’s skill set matches up particularly well with the park he’s in today, which may lead to better-than-usual performance.

Washington Nationals Insights

• Jake Irvin – Over/Under Pitching Outs
  Jake Irvin has averaged 92.1 adjusted pitches per game per started this year, placing in the 79th percentile.
  Explain: Pitchers who average more pitches per game are more likely to go deeper into games and record more outs.
• Daylen Lile – Over/Under 1.5 Total Bases (+120/-150)
  The leading projection system (THE BAT X) estimates Daylen Lile’s true offensive skill to be a .311, indicating that he has had some very good luck this year given the .041 difference between that mark and his actual .352 wOBA.
  Explain: Players that are overperforming should be expected to play worse going forward, which can create value on prop Unders if the lines are too heavily weighing the lucky, to-date overperformance.
• The Washington Nationals have 3 hitters in their projected lineup today with a high (i.e. over 27%) underlying K% (according to the leading projection system, THE BAT X) (Paul DeJong, Riley Adams, James Wood).
  Explain: Teams that have multiple high-strikeout hitters will make it much easier for the opposing pitcher to record strikeouts
