Home run pick: Yordan Alvarez (+215)

Houston slugger Yordan Alvarez enters Monday’s slate with arguably the best matchup of the day, drawing Minnesota Twins right-hander Zebby Matthews, against whom Alvarez has nearly 100% arsenal coverage.

The Minnesota right-hander has struggled mightily against left-handed hitters, allowing nearly a 70% elevation rate, a 40% hard-hit rate, and an 11.5% barrel rate over his last 60 left-handed batters faced. Those hitters have posted a .663 xSLG and a .476 xwOBA during that span.

Despite Alvarez’s .200 average over his last 30 plate appearances against right-handed pitching, he is still generating a 43% hard-hit rate and a 14.3% barrel rate, while posting a .403 wOBA.

The price is not ideal, but given the overall matchup, it is justified.

Home run pick: Pete Alonso (+279)

For those who read how much I loved Baltimore Orioles slugger Pete Alonso to go Over 1.5 total bases against Sean Burke, in my MLB player props for tonight, how could I pass up his home run prop? Especially when the Chicago White Sox right-hander has allowed over a 76% elevation rate to the last 60 right handed hitters he has faced.

To add to that, Alonso has been seeing the ball extremely well of late, posting a 20% barrel rate, .792 SLG, and .523 wOBA over his last 30 plate appearances against right-handed pitching.

This matchup has extra base hits written all over it. Hopefully one of them leaves the yard.
