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. In Harper's game, our HRForce Index at first pitch is 1.4 [40% more HRs expected]. Meanwhile, Alonso will be playing under an HRForce of 1.3 [30% more HRs expected]. So, the ball will be flying better in Harper's game. Weather edge goes to him.
Weekly Roster Lock Leagues
For those of you in leagues that require you to set your lineup before the start of each week, off-days can be a bummer. Everything else being equal, give the edge to guys that play at least one more game a week. For the Mon-Sun week that includes 4/10/26, Harper has 6 games scheduled, while Alonso has 6. With the same number of games, they roughly carry the same potential value for the week.
