Today, neither batter has more than 3 plate appearances against their opposing pitcher so there's not enough real data to make a matchup call. Use the other splits on this page to make a decision.
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 1.3 [30% more HRs expected]. Meanwhile, Alonso will be playing under an HRForce of 1.2 [20% 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, 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 4/14/25, Harper has 7 games scheduled, while Alonso has 7. With the same number of games, they roughly carry the same potential value for the week.
