Heineman's last action came in the NPB as a member of the Yomimuri Giants, but he spent only 10 games with the club. He's a career .172/.249/.325 hitter over 173 plate appearances at the highest level, and provides organizational depth for Seattle and Triple-A Tacoma.

Heineman is expected to sign with a team in Japan. He is a career .172/.249/.325 hitter over 173 plate appearances at the major league level.

Heineman was designated for assignment earlier this week and ultimately passed through waivers unclaimed. The 28-year-old is a career .172/.249/.325 hitter over 173 plate appearances at the MLB level.

The move clears a spot for Alejo Lopez on the 40-man roster. Heineman went 3-for-30 (.100) with 15 strikeouts during his time with the Reds this season.
