Why Ogasawara Struggled in the Majors

1. Home Run Problems

His biggest challenge was limiting hard contact.

With a four-seam fastball averaging around 146 km/h (91 mph), Ogasawara lacked the overpowering velocity often required in Major League Baseball. He surrendered nine home runs in just 38.2 innings, which significantly inflated his ERA.

2. Difficulties as a Starter

His ERA as a starter climbed above 9.00, leading the Nationals to move him into a bullpen role.

From August onward, he showed flashes of improvement as a reliever and was able to produce more consistent results in shorter outings.

3. Secondary Pitches Showed Promise

Despite the struggles, scouts and coaches continued to praise his pitch mix, which includes:

• Slider
• Knuckle curve
• Changeup

Those pitches allowed him to remain effective in certain situations and suggest that his overall skill set still has value.

What Role Will Ogasawara Play with the Giants?

The Giants are expected to return Ogasawara to his natural role as a starting pitcher.

Several factors make him an attractive addition.

Familiarity with Central League Hitters

Having spent nine seasons in NPB, Ogasawara possesses extensive knowledge of opposing lineups and understands how to attack many of the league’s hitters.

His experience should allow him to make a smooth transition back to Japan.

Proven Innings-Eater

One of Ogasawara’s greatest strengths has been durability.

Reaching the qualifying innings requirement in four consecutive seasons demonstrates his ability to consistently take the mound and reduce the burden on the bullpen.

As the season enters its demanding summer stretch, that reliability could become extremely valuable.

Addressing the Lack of Left-Handed Starters

Quality left-handed starters are always in high demand.

If Ogasawara performs near his previous NPB level, the Giants’ rotation depth will improve considerably and provide manager Shinnosuke Abe with additional flexibility.

Fan Reactions to the Move

Giants Fans Welcome the Signing

The majority of Giants supporters have reacted positively.

Many fans have described Ogasawara as:

• The final piece in a championship run
• A statement signing that demonstrates the organization’s ambition
• A key addition that strengthens the starting rotation

Optimism surrounding the move has been widespread.

Mixed Feelings Among Chunichi Dragons Fans

For Dragons fans, emotions have been more complicated.

Some supporters had hoped for a reunion with their former ace and were surprised that a return to Nagoya never materialized.

Others expressed sadness over seeing a longtime franchise player join one of Chunichi’s biggest rivals.

Rival Fans Recognize the Threat

Fans around the Central League have also taken notice.

Some pointed out that a pitcher who frequently caused problems for opposing teams now joining the Giants makes the club even more formidable heading into the second half of the season.
