Home run prediction: Yordan Alvarez (+276)

Saying someone is "due" is so overused in this space, but Houston Astros slugger Yordan Alvarez has not hit a home run since July 28th. Yes, 17 days ago. The big fella has gone into a bit of a slump, but has still been generating quality contact. Over his last five games, he has a 50% hard-hit rate and 21.4% barrel rate.

Alvarez enters Friday with the number one matchup rating on Batters-Box, where he has left the yard nearly 37% of the time in 19 home games this season. Overall, through 41 elite ratings in 2026, he has homered in 26.83% of those games.

Seattle Mariners right-hander George Kirby has allowed 2.57 HR/9 to his last 60 left-handed hitters faced, while those hitters are elevating the baseball at nearly a 78% clip.

Again, is anyone ever due for anything? Nope, but this looks like a pretty good spot for Alvarez.

Playable to +250.

Home run prediction: Jac Caglianone (+307)

We are kicking off our Friday by backing the Italian Stallion from Kansas City, Mr. Jac Caglianone, who finds himself in a delectable spot against Los Angeles Angels right-hander Grayson Rodriguez.

The Kansas City Royals slugger enters today with an elite rating on Batters-Box's current-season dataset. He not only covers 100% of Rodriguez's pitch mix, but he has also left the yard on 30.43% of his 23 elite ratings this season.

Caglianone has been seeing the ball extremely well over his last 30 plate appearances against right-handed pitchers, owning a .333 BA, .667 SLG and 1.034 OPS while producing a 58% hard-hit rate and 12% barrel rate. On top of that, over his last five games, he is generating nearly a 60% hard-hit rate and an 18% barrel rate.

With how poorly Rodriguez has been against left-handed hitters this season, the big fella is in a great spot to go deep tonight on the road. Take this down to +275 at the most.
