Yokohama Baystars vs Yomiuri Prediction 18 August 2026
📡 DeNA return home after suffering three straight defeats against Yakult, while Yomiuri wrapped up their trip to Nagoya with a commanding 11-0 victory over Chunichi. The hosts currently sit fourth in the standings at 48-56-3, while the visitors hold second place with a 57-48-2 record. The prediction hinges largely on the form of the starting pitchers, as both allowed at least four runs in their most recent outings.
Head-to-Head
📊 Over their last ten head-to-head meetings, Yomiuri have held the upper hand with seven wins to DeNA’s three. The visitors also lead in runs scored, 38 to 32, with an average total of exactly 7.0 runs per game. Notably, the 7.5-run mark has only been surpassed in three of those ten matchups, although two of the three games played in August produced totals of 15 and 3 runs, respectively.
Head-to-head statistics Yokohama Baystars - Yomiuri

Yokohama Dena Baystars Team Overview
DeNA have dropped four of their last six games, including all three matchups in the recent series against Yakult-falling 2-7, 3-4, and 1-2. Over that six-game stretch, the team have put up 19 runs, but their offense notably sputtered in the latest series. Still, DeNA have shown they can deliver at the plate at home in August, putting together high-scoring contests against Hanshin-11-7 and 5-10. Heading into the new series, the hosts face another issue: their starting pitcher lasted just 2.1 innings in his previous outing.

In the season series against DeNA, Yomiuri lead 11-5, having scored 62 runs with a .258 batting average. Their consistent production against the hosts remains a key factor heading into this matchup.

⚾ Projected Starting Pitchers
Syuto Ogata, the right-hander for DeNA, has made 10 starts since joining the club, posting a 3-3 record with a 3.42 ERA over 50.0 innings. He’s allowed 36 hits, struck out 56, surrendered 19 earned runs, and holds a 1.26 WHIP. His most recent outing was a struggle-against Chunichi, Ogata was tagged for 6 hits and 4 runs in just 2.1 innings. Only four of his ten starts so far would qualify as quality outings.
Iori Yamasaki, a righty for Yomiuri, has started four games this season, going 1-1 with a 5.01 ERA across 23.1 innings. He’s given up 26 hits, recorded 18 strikeouts, conceded 13 earned runs, and carries a 1.50 WHIP. In August, his ERA has climbed to 6.00, and in his latest appearance against Hanshin he was hit hard for 6 runs and 8 hits over 5.1 innings. So far, just one of Yamasaki’s four starts meets the criteria for a quality start.
⭐ Editor's Pick
The head-to-head history between these teams generally points to low-scoring affairs, but this time around the starting pitchers present a very different picture. Ogata lasted just three innings in his most recent outing, while Yamasaki allows over five earned runs per nine innings on average and has been especially shaky in August. Yomiuri are coming off an 11-run performance, and DeNA have already been involved in several double-digit scoring games this month. If either starter fails to go deep again, an early call to the bullpen will only increase scoring opportunities for both sides. That’s why we’re backing the over 7.5 total runs here.
