So, should you choose Westburg or Semien (4/20/25)?
Batter vs pitcher
Semien has faced Glasnow 9 times, with a total OPS of 1.888. Conversely, Westburg has no plate appearances against Wynne. Since Semien has good matchup numbers today, lean towards him.
Weather impact
Heavy wind (blowing out), hot temps, ballpark elevation, etc can all have a big impact on long fly balls. An extra few feet can be the difference between warning track and a 3-run dinger. Neither game has a current forecast so no HRForce just yet (weather impact on long fly balls).
Weekly Roster Lock Leagues
For those of you in leagues that require you to set your lineup before the start of each week, day offs can be a bummer. Everything else being equal, give the edge to players that play at least one more game a week. For the M-F week that includes 4/20/25, Westburg has 6 games scheduled, while Semien has 6. With the same number of games, they roughly carry the same potential value for the week.
