Editor's note: A version of this story originally was posted in advance of Thursday's season opener. It has since been updated.
The Bryce Harper Phillies era has begun, with Philadelphia and the Atlanta Braves wrapping up a season-opening series on ESPN's Sunday Night Baseball (7 p.m.). Before Harper took the field in his new uniform for the first time, we asked five of our experts to predict how things would go during the $330 million man's inaugural season in Philadelphia.
Bryce Harper is a .279 career hitter. Are you taking over or under that number for 2019?
Bradford Doolittle: Under. Putting his career in a Citizens Bank Ballpark context adds only a couple of points to his batting average, and I suspect he'll be more focused on the long ball in his first Philly season.
Sam Miller: Over. Nothing fancy about my reasoning: I just think he's better than his career numbers. Easier to explain away the bad years than explain away the amazing ones.
Eddie Matz: With seven seasons of data on Harper, that .330 average from his MVP season is looking more and more outlier-ish. Plus, the average average in MLB fell from .255 in 2017 to .248 last year. I'll have the under, please.
Jeff Passan: Give me the over. The National League East is chock full of right-handed starters, and Harper's career batting average is 30 points higher against them. And there's the whole every-other-year thing, which Harper obviously picked up after the Giants' run ended.
David Schoenfield: I can't remember a player seesawing back and forth with such extremes in his batting average, but I'm taking the under mostly because Harper's swing-and-miss and strikeout rates increased last year, and you're not getting hits if you're not putting the ball in play.
Harper hit 34 home runs in 2018. Are you taking over or under that for this season?
Doolittle: Over. Better homer ballpark, and as I said, I think he'll be going for the pump in his first season with a new team. He might be inconsistent overall, but he's pretty consistent when it comes to going deep.
Miller: Over. For the same reason as my batting average answer earlier.
Matz: Harper's home run rate at Citizens Bank Park (6.7 percent) is 50 percent higher than his rate at all other parks combined (4.5 percent). I'll have the over, please.
Passan: In the live ball era, only 17 players before Harper put up an OPS of at least .900 through their age-25 season with a minimum of 3,000 plate appearances. The average number of home runs in their age-26 season: 33.1. If that's the ballpark -- and Citizens Bank bandbox is Harper's actual ballpark -- I'm a strong over.
Schoenfield: Citizens Bank Park should give Harper a couple of additional cheap home runs, but will he get a career-high 695 plate appearances again? I'll take the over, but only by one or two.
Harper posted a 3.5 WAR last year (using Fangraphs). Will he beat that number this year?
Doolittle: Over. Give Harper even a modest regression in BABIP and an improvement on defensive numbers so bad they'd be hard to repeat and you've got a 5-win player at minimum.
Miller: He will. He's just better than that!
Matz: Instead of trying not to get hurt, he'll be trying to win over Philly fans. That should translate to better defensive metrics, which translates to me taking the over here.
Passan: Publicly available defensive metrics are notoriously finicky -- that's a kind way of saying they're not altogether trustworthy -- so it's a risk saying yes when they're a clear part of the equation. But if he hits over .279 and has more than 34 homers and walks the way he did last year, the answer will be yes.
Schoenfield: We know he'll hit for power and take his walks, and his defensive metrics can't be worse than in 2018 (he didn't dive for a single ball all season). He should be more relaxed with the contract in hand. Over.
Number of postseason at-bats for Harper in his first year with the Phillies. Over or under ... 1?
Doolittle: Under. The Phillies certainly can make the postseason, but I've got them behind the Nationals and Braves, and one of the wild cards is likely to go to a Central team.
Miller: Goodness, that's a close one. I buy the Phillies at about 50 percent to make it, and there's a non-zero chance Harper gets hurt and isn't active in October, so I guess I'm forced to say under.
Matz: I've got the Phils slotted for a wild card. So unless they lose the wild-card game and Harper walks every time up to bat (or gets hurt), I'm all about the over.
Passan: I think the Phillies are a wild-card team. Harper also went 0-for-0 with five walks against Miami last September. So he could make the playoffs and not get an at-bat. (Stop being pedantic.) Fine, over.
Schoenfield: Under. I have the Nationals winning the division and the Phillies JUST missing one of the wild cards.
When will Harper play his first World Series game?
Doolittle: Oct. 23, 2023. It's a tough division and the Braves and Nationals should have staying power. The Mets ... we'll see, but the Marlins could conceivably leap up to win a World Series and then sell off all their players in a couple of years as well. The Phillies will get their turn at some point.
Matz: A year after he waives his no-trade clause and ends up in pinstripes.
Schoenfield: I mean, 13 years is a long time. I'm putting each year on a piece of scrap paper and drawing one out of a hat and the winner is ... 2024.
Pick one or the other:
Higher finish in the NL East this season: Harper's new team or his old team?
Miller: Nationals were my pick for the NL East, I think.
Matz: Old team. I've got the Nats riding their starting rotation to an NL East title.
Passan: Old team. I've got the Nationals winning the NL East.
Schoenfield: The old team.
Bryce Harper's finish in 2019 NL MVP voting -- inside the top five or outside the top five?
Doolittle: Inside. If the Phillies don't win the division, it won't be his fault. He has a lot of doubters to silence, and he's just the sort of bloke to be motivated by stuff such as that.
Miller: Probably outside, but just because I'm a coward and I'm considering the literal odds instead of picking the fun answer that accurately conveys my general sentiments about his outlook.
Matz: WAR has become such a strong indicator for MVP balloting, and there are too many guys that I see finishing ahead of Harper in that category. So ... outside.
Passan: Not just inside. He wins it.
Schoenfield: The NL has so many MVP candidates, and voting tends to at least slightly favor players on playoff teams -- and I have the Phillies missing the playoffs, so I'll say outside the top five.
