Koji Uehara and Junichi Tazawa were two of the last Red Sox players to leave the clubhouse on Wednesday night after a 6-3 victory against the Indians.

They sat at a table sharing dinner with their interpreter, C.J. Matsumoto. Tazawa pitched two innings, Uehara one, and Matsumoto had a busy night helping the two pitchers conduct postgame interviews.

Because they are from Japan and are pitchers, it’s easy to assume Uehara and Tazawa must be close friends.

They are actually not. The 38-year-old Uehera has been pitching professionally for 15 years now and is a family man. His son, Kazuma, accompanies him to the park on occasion.

Tazawa, who is 26, has a far different background. He successfully challenged the system, telling Japanese teams not to draft him so he could sign with the Red Sox in 2008. He made his major league debut a year later.

Their personalities are different, too. Uehara is one of the funniest players on the team, using piecemeal English to crack jokes. He rushes to the dugout after successful outings, eager to celebrate with teammates.

“A fun guy to be around,” manager John Farrell said.

Tazawa is quiet and rarely draws attention for anything beyond what he does on the mound.

Where Tazawa and Uehara are similar is in what they have meant to the Sox this season.

Tazawa entered the game in the sixth inning on Wednesday with a runner on second and no outs.

The Indians had just scored three runs off a tiring Alfredo Aceves on a pair of long home runs by Nick Swisher and Jason Giambi.

The Sox were up, 5-3, but the game was on the line. Farrell wanted to get six innings out Aceves after Felix Doubront lasted only five innings on Tuesday and it was a miscalculation.
