Full All-Star Week coverage: How to watch, schedule, more

Junior Caminero, Tampa Bay Rays

2026 home runs: 26 | Longest: 463 feet

Why he could win:Is there anyone hotter in baseball than the Rays slugger right now? The reigning AL player of the week and month has turned the past couple of weeks into his own personal home run derby, including a streak of six straight games with a long ball. If swinging a hot bat isn't reason enough, Caminero owns the average fastest bat speed in the majors (80.0 mph) and also finished second in the event last year, so we already know his powerful bat translates to the Derby stage.

Why he might not: Youth? Despite that runner-up finish as a 22-year-old last summer, no player as young as Caminero is now has ever won the Derby. In fact, if Caminero is the last slugger standing in Philly, he would be 257 days younger than a 23-year-old Juan Gonzalez.

Ben Rice, New York Yankees

2026 home runs: 25 | Longest home run: 433 feet

Why he could win:Rice has been one of the true breakout power stars of the past year-plus, belting 51 home runs since the start of the 2025 season and nearly matching his career high set last season in just 315 2026 at-bats. His average exit velocity (91.8 mph) is in the 87th percentile and his barrel rate (14.7%) is in the 89th, so Rice is capable of hitting the ball hard and doing so often -- a great recipe for Derby success. As for any fear of this being his first Home Run Derby being a negative? The past two Derby champions -- Cal Raleigh and Teoscar Hernandez -- were competing in the event for the first time.

Why he might not: Despite his breakout production, Rice still has some swing-and-miss issues in his game. He has struck out 86 times in 85 games this season and has a24.9% whiff rate. Winning the Home Run Derby is about stringing together multiple rounds of consistent home runs, and getting out of a rhythm can spell doom for any slugger.

Jac Caglianone, Kansas City Royals

2026 home runs: 14 | Longest home run: 444 feet

Why he could win:In his short time in the majors, Caglianone already ranks among MLB's elite when it comes to hitting the ball hard. He's in the top 12 in the sport in average exit velo, max exit velo, 50th percentile exit velo and hard-hit percentage. He's also in the midst of putting those metrics together during the best stretch of his career, mashing nine home runs in June.

Why he might not:Despite his recent surge, Caglianone has struggled at times during his MLB career -- especially when it comes to making consistent contact. Unlike his standout exit velo metrics, he ranks in the 20th percentile of hitters in squared-up percentage, 16th percentile in chase rate, 14th in whiff% and 11th in K%. All of which could add up to a very hit or miss Derby.

Willson Contreras, Boston Red Sox

2026 home runs:20 | Longest home run: 449 feet

Why he could win:Contreras' production has been one of the biggest bright spots in a rough season for the Red Sox. At age 34, he is having his best power season -- his 20 home runs in 87 games matches his season total from last year and is just four behind his career high. And his Statcast data supports the late-career spike as his .513 xSLG ranks in the top 8% of MLB hitters and his 114.4 max exit velo in the top 6%. And before you chalk it up to playing in Fenway Park in his first season with the Red Sox: Contreras at home this season -- 10 home runs; Contreras on the road this season -- 10 home runs.

Why he might not:Citizens Bank Ballpark has a reputation for being friendly for left-handed hitters, and Contreras is a right-handed pull hitter. In fact, just one of his 20 home runs this season has been to anywhere other than left field -- and that was a 411-foot shot to center field. Combine that with Contreras' age (Dave Parker is the oldest Derby winner at age 34 way back in 1985) and it could be an uphill fight for the Boston slugger.

Jordan Walker, St. Louis Cardinals

2026 home runs: 21 | Longest home run:459feet

Why he could win:One of the true breakout stars of the 2026 MLB season, Walker is built to withstand the rigors of the Derby -- literally. He stands 6-foot-6 and is listed at 250 pounds and has finally put it all together this year, already besting his career high in home runs (and nearly every other offensive category). His Baseball Savant page is also filled with red in bat speed (100th percentile), exit velo (98th percentile) and hard-hit% (93rd percentile).

Why he might not:Like some of the other young sluggers in this field, swing-and-miss is Walker's biggest weakness. His Baseball Savant page turns blue quickly when you get to the contact categories: 17th percentile in whiff%, 21st percentile in chase% and 28th in K%. Yet another player who could boom -- or bust -- in Philly.

Bryce Harper, Philadelphia Phillies

2026 home runs:20 | Longest home run: 457feet

Why he could win:Are you going to doubt Bryce Harper? In his own ballpark? Need we remind you of what he did in 2018, when he won the Derby in his home ballpark during his final year with the Nationals? Not only that, but Harper has regained his power stroke in 2026, already closing in on last season's home run total (27) and raining his slugging percentage over .500 once again. One thing is for sure. If Harper gets hot in the Derby, the Bank is going to be rocking.

Why he might not:Harper is 33 years old, and some of his underlying power metrics are a tick behind others in this field. He's still an elite hitter, don't get us wrong, but his exit velo (66th percentile), barrel% (78th percentile) and hard-hit% are more good than great at this point in his career.
