Last month, I developed home run park factors using Statcast’s metric – Barrels. I used four full seasons of Statcast data to determine the most favorable and unfavorable parks in Major League Baseball. Let’s put this information to work and determine which players have been unlucky or are underperforming and players who have been lucky or are overperforming their power metrics based on HR/BRL rate. I’ll look at how players have performed in the past, look at park factors, and compare their numbers to the league-average HR/BRL rate in 2019. Speaking of which, that metric (HR/BRL%) is currently 55.96%. I deduct home runs that do not qualify as a barrel in that calculation. I separate them out and call those home runs “lucky” or non-barreled homers.
First, let’s look at the underperformers. You’ll want to sort the column to the right (HR/BRL%). Remember 55.96% is league-average, so sort the column further to the right to if you want to to see the largest underperformers. The HR (BRL) column are all the home runs that were also barrels and the number from that column plus the Lucky HR column should equal the player’s total HR to date. Hit me up if you have questions or want to know about a player on the list I didn’t cover.
HR/BRL Underperformers (5/31/19)
|Player||BRL||HR (BRL)||Lucky HR||HR Total||HR/BRL%|
David Dahl – How in the hell does a Rockies hitter have the lowest HR/BRL rate? When we go over the overperformers, we find Nolan Arenado (85.7%) and Trevor Story (71.4%). Of course, we know based on their home park, those numbers are not out of bounds. I absolutely hate his (Dahl’s) approach and his contact rate is atrocious but Coors field! He’s due some serious positive power regression as long as the Rockies stick with him. Unfortunately, he’s running an elevated BABIP inflating his batting average, so it’s not like you can get him for cheap. I wouldn’t be surprised if he goes on a binge over the summer months and ends up close to 30 home runs.
Andrew Benintendi has picked up his pace in recent weeks. I was high on him this offseason and expected him to take a step forward in terms of power. The good news is he’s just about halfway to his total number of barrels from 2018 but has only produced six homers. Fenway isn’t great for left-handed pull power which is what Benny produces. I still think he’s due some positive regression and a 20-20 season is well within reach.
No surprise here, Jose Ramirez has been unlucky this season. That doesn’t mean he’s been good though. Ramirez thrives by commanding the strike zone, making a ton of contact and doing damage to the pull side. This year, he’s declined in all three facets. As far as his power, he’s not hitting 39 homers, sorry. But, for a home park that’s neutral for power, he should have a couple more home runs. I think he’ll heat up and end up with around 20 home runs to go with 30 steals which isn’t so bad but not a top five player.
Yes, Christian Walker homered last night, but he’s been ice cold. With the addition of Kevin Cron to the MLB roster, Walker will fade in the remaining four months. Yes, he’s been unlucky, no I’m not buying.
J.T. Realmuto plays in a favorable park with a stacked lineup. His power and Statcast metrics look great and clearly, he’s been extremely unlucky in terms of HR/BRL rate. Find an owner who is tired of his mediocre statistics and pluck him up for cheap because, I think he ends up around 25 homers this year with career-best counting stats.
This offseason, I predicted Anthony Rendon would win the MVP this year and even after missing over two weeks to an elbow contusion, he still ranks sixth in the NL in WAR. He’s only managed 10 home runs on 23 barrels (1 lucky HR) to date. Just regressing Rendon to league-average HR/BRL, he would have 14 home runs in just 43 games played. If he can stay healthy and luck falls on his side, he should have no problem reach 30-35 homers with a slash line of .300/.400/600 and a top 3 MVP candidate.
Freddie Freeman is currently underperforming his HR/BRL rate for the third straight season. New Suntrust Park did not fair well (25th in HR Park Factors) since inception in 2017. Freeman hits a ton of line drives at high exit velocities that may be registering as barrels. However, they might not have enough loft or backspin to reach the seats, especially in Suntrust. It’s too bad because he may be having the best season of his career with a career-low 16.7% strikeout rate.
You might be surprised to find out that the 2019 barrels leader is Jose Abreu. Abreu heats up in the Summer months and already has 15 home runs. He’s striking out more also making more contact on pitches in the zone. His HR/FB rate is the highest since his rookie season and at age-32, he’s at the back-end of his power prime. Given the current environment and the improved White Sox lineup, I like Abreu to match or even best his home run total from his rookie season. I can envision a .270-40-120 type of line.
LOL Mike Trout LOL
I have to touch on my guy Ketel Marte. He just hit a ball 115.8 MPH yesterday which is harder than any ball Joey Gallo has hit this year. The metrics back up his power improvements and he’s actually pulling 39% of his fly balls which is key for power. The point is, I don’t expect regression from Marte going forward. I’d put him down for 25-28 home runs with a good batting average and plenty of R+RBI hitting 2nd or 3rd in the Diamondbacks lineup.
HR/BRL Rate Overperformers (5/31/19)
|Player||BRL||HR (BRL)||Lucky HR||HR Total||HR/BRL%|
|Tommy La Stella||10||10||2||12||100.0%|
Jose Peraza is probably the luckiest hitter in the league in terms of home runs. He has totaled five home runs on just one barrel! I can’t put a whole lot of stock into these metrics because #1, it’s such a small sample and #2, he plays his home games in GAB, the best park in MLB for homers. He also did similar things last year hitting 14 homers on 14 barrels. I’m not interested in Peraza going forward but he could still luck his way into 10 HR and 15-20 steals.
Wow, another Red, surprising. After hyping Jesse Winker for the better part of a year now, I’m cooling a bit on him. His batted ball metrics have taken a dip over the last three weeks. It could just be a minor injury or an approach change (not in a good way) but I still like Winker going forward. Even with the extreme homer-friendly park in Great American Ballpark, I don’t think he’ll continue his power pace. He’s still on pace for just under 30 homers but I’d expect something closer to 25 with improvements in batting average. He’s still a top 200 player going forward.
It probably doesn’t take an expert to figure out Tommy La Stella has been extremely fortunate in the power department this season. He’s managed to hammer out 12 home runs while only barreling 10 balls. He’s homered on all 10 of his barrels and assuming league-average HR/BRL rate, he should have between five and six home runs. He’s also hit two “lucky” home runs and five of his 12 home runs were hit with an exit velocity under 100 MPH. Everywhere I look, I see regression including his 20.4% HR/FB rate which is seven percent higher than his previous career-high. His average HR distance is 392 feet. His average EV on FB/LD is only 91.6 MPH which ranks 152 out of 204 batters with at least 100 batted balls sandwiched between Steven Duggar and Amed Rosario.
Alex Bregman has homered on over 93% of his barrels and has totaled more home runs than barreled balls. This is a guy who hit 31 home runs on 39 barrels last season and averaged only 384 feet on his home runs. Interestingly enough, Bregman is not taking advantage of the short Crawford boxes in Minute Maid Park. In fact, only one home run was aided by the Crawford Boxes. It was hit on 5/22 and went just 352 feet with an exit velocity of only 93 MPH with an xBA of just 0.068. He doesn’t have monster power but his short and quick swing generates enough power to all fields. I think his home run rate declines on balls to the opposite field, but the rest of his profile looks legit.
I was stuck between Hunter Renfroe and Franmil Reyes in the preseason but after the first two months, I’m much more excited about Framil. Renfroe still has some solid value, especially if he plays every day but it will likely come with a drain on batting average. He’s been lucky in the power department but as I learned last month, Petco Park is a top 10 park for home runs. I also noticed Renfroe is pulling 53% of his fly balls which is the most in the league among hitters with at least 40 fly balls. That’s a great why to inflate your HR/FB rate, so while I expect some regression, it shouldn;t be drastic. I think Renfroe reaches 30 homers for the first time but might have to wait another year or two in order to reach to 40 homer milestone.
Mr. Swag himself, Derek Dietrich has been fortunate to have a home run total of 17 through the first two months. It’s been impressive, there’s no doubt but in a list of 23 overperformers to date, four of them play for the Reds. He’s another guy pulling a high eprcentage of his fly balls. He’s selling out for power increasing his fly ball rate by 16%! He’s also improved his hard contact but is popping up too much as well. He’s going to go through slumps and crater batting averages but the backdrop of GABP should net Dietrich another 15 or so homers.
Joc Pederson is interesting because he hits some absolute moonshots. Three of his home runs this season were hit at 35-degree launch angles or higher, one reached 43 degrees! He also love hitting in LA where 11 of his 16 home runs have come at home. Dodger Stadium scored as the 11th best park for home runs (1.05 PF) but where it’s very favorable is down the lines where it’s 330 feet. Pederson is able to take advantage of the short right field fence and can hug several moonshots. He still can’t hit lefties and will be on the bench against them, so manage Pederson accordingly.
Dan Vogelbach doesn’t hit many wall scrappers. He has hit two lucky home runs but it’s likely due to the low launch angle of the home runs, not the lower exit velocity we see with the likes of Tommy La Stella. To give you an idea of what I mean, 10 of his 15 home runs have been hit at launch angles of 23 degrees or lower. Most of those were absolutely crushed at exit velocities of 104 MPH or higher. Most home runs are hit between 22 and 32 degrees +/- in terms of launch angle. Vogelbach is trying to buck that trend. As the weather heats up, the balls will only travel further, so I’m not expecting regression from Vogelbach, even though he finds himself on this list.
