Keith has faced Wacha 9 times, with a total OPS of 1.000. Conversely, Rafaela has no plate appearances against Burke. Since Keith 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, Rafaela has 6 games scheduled, while Keith has 7. So, with one more game, that could make a difference, especially in H2H leagues where you need to pile up points. Slight advantage to Keith.
