Mike Trout has one of the clearest paths to a power surge on today's slate, as the conditions in Anaheim are among the most ideal on the board. Stepping in against Aaron Civale only sweetens the deal.

It's a getaway slate with lots of potential rain spots on the board. The hot weather has come and gone, so digging for some home run gems and MLB player props means circling the few HR-plus matchups.

Merrill Kelly is coming back down to Earth today after going the distance at Coors Field in his last start, and the HR potential in Anaheim today might be the best on the board.

These are my favorite MLB home run predictions for Wednesday, May 20.

Home run pick: Mike Trout (+316)

I'm kicking myself for avoiding Mike Trout yesterday in a good spot, but at a sub-300 pricetag, it was a pass. That won't be the case today at +316 with a fair price at +280. Trout snapped a 12-game HR drought last night in Anaheim, and his swing speed is not dropping as we enter the Summer months of the season, which can be a worry for the oft-injured outfielder.

Trout gets Aaron Civale, who is a bottom-25 starter in BlastCont% and a pitcher he has already taken deep in a small six-at-bat sample. He isn't the only Halo projecting +EV, as Zach Neto (+433) and Jo Adell (+399) are also on the list. Neto has been crushing, and I bet Adell in yesterday's MLB picks, so the day-after theory is in full effect.

With a lot of rain on the slate, 6-mph winds blowing out to center with mid-70-degree temperatures are creating one of the better hitting environments with a pair of bad bullpens.

Home run pick: Willy Adames (+557)

I have Merrill Kelly ranked as one of the worst starters on the board today. He gets hit hard, his fly balls leave the yard, and the expected metrics suggest the damage is fully deserved. He’s also coming off a complete game, and that recent two-start stretch against weaker offenses feels due for a hard correction. Just three starts ago, he was carrying a 9.95 ERA with six home runs allowed over a 19-inning span.

Willy Adames is the target today, and Rafael Devers was unfortunately left off the card yesterday despite getting plenty of consideration. Adames has logged 25 at-bats against Kelly, which is a meaningful sample and gives the hitter a sizeable information edge. He’s already taken him deep twice and owns a .946 OPS in the matchup.

Adames has homered in back-to-back games and has an extra-base hit in four of his last five. I’m backing the hot bat in what could be the best starting pitcher matchup on the board, especially with potential weather concerns hanging over the Zack Littell spot.
