Bryce Harper, the Phillies' star first baseman, confirmed he will take the mound at the Home Run Derby on Monday night at Citizens Bank Park. The 33‑year‑old slugger posted a .261 average with 20 homers and 57 RBIs in the 2026 season. He is a Legend Pick for the All‑Star Game and aims to become the fifth player to win the derby twice.

Jordan Walker, the Cardinals' 24‑year‑old outfielder, joined the lineup as a first‑time All‑Star. He hit his 22nd homer on Thursday and is batting .294 with an driven .889 OPS, leading MLB with 70 RBI. The 2020 first‑round pick is on a breakout run and will be the eighth Cardinals player to compete, but no franchise winner yet.

The contest also features Willson Contreras, Jac Caglianone, Junior Caminero and Ben Rice. Harper’s return to Philadelphia after winning in 2018 at Washington adds a hometown narrative. A second title would cement his legacy among players who maximum twice, while Walker’s performance could boost his stock heading into the postseason.
