The Pro Yakyuu: Pennant race

The Pro Yakyuu: Pennant Race (ザ・プロ野球 ペナントレース) is a Sega Master System baseball game developed by Whiteboard and published by Sega.

Exclusively released in Japan in 1987, the game is an evolution of the developer's earlier title Great Baseball, and is now played from a bird's-eye perspective.

The Sega Master System (1985/1986) was Sega's answer to the NES and, while it lost the console war in North America, became genuinely dominant in markets like Brazil and parts of Europe. That regional split matters for collectors: PAL and Brazilian-market cartridges can differ meaningfully in scarcity and pricing from their North American counterparts for the same title.

Gamevaro tracks The Pro Yakyuu: Pennant race for Sega Master System with separate market values for loose, complete-in-box (CIB) and factory-sealed copies, sourced from real eBay sales. Prices also vary by region — PAL, NTSC-U and NTSC-J releases of the same game often sell for different amounts due to print run sizes and regional collector demand.

Adding The Pro Yakyuu: Pennant race to a Gamevaro collection takes seconds — search by title or scan the box barcode, and the app fills in cover art, release details and current pricing automatically. This SMS release dates back to 1987.

Only a handful of market sales have been tracked for The Pro Yakyuu: Pennant race, suggesting it doesn't trade hands very often — a sign of relative scarcity compared to more common Sega Master System titles.

Complete-in-box (CIB) copies typically command a premium over loose cartridges/discs because the original box and manual are more fragile and get discarded or damaged over time — fewer complete sets survive.
