Diaz went 1-for-4 with a solo home run in Saturday's 4-0 win over the Reds.
He went back-to-back with Alex Jackson off Andrew Abbott to lead off the fifth inning, breaking open a 1-0 game. While the homer was only the ninth of the year for Diaz, a disappointing total after he slugged a career-high 22 last season, he has been supplying more power in July, slashing .278/.328/.481 through 13 games on the month. The 32-year-old is on an affordable contract that pays him $10 million in 2025 with a $12 million club option for 2026, but with the Rays in sell mode at the trade deadline and a number of contenders in need of help at first base, Diaz could be the next player to go.
