Detroit's Valencia Tops a Deep Rookie Class

AUGUST 29, 2026

The first-year players worth watching.

The kids get the column today. Eduardo Valencia has quietly outhit every other rookie, Munetaka Murakami keeps thumping homers in Chicago, and Tristan Peters is riding one loud week into the conversation. Here's the freshman board.

The rookie class

Top first-year players, hitters by OPS (minimum real playing time).

Eduardo Valencia leads the rookie hitters at a 1.032 OPS for Detroit, the only one in that group above the 1.000 mark, though his six homers say he does it with line drives more than thunder. Behind him, Munetaka Murakami brings the power on the White Sox with 29 home runs and an .865 OPS. On the mound, San Diego's Bradgley Rodriguez owns the best rookie ERA at 1.95.

Rookies breaking out

Rookies with the biggest OPS jump this week.

Tristan Peters had the week that mattered, his OPS jumping 65 points to .817 for the White Sox. The Cubs' Pedro Ramírez climbed too, up 41 points to .785.
