OAKLAND, Calif. -- Saturday marks the one-year anniversary of the day Koji Uehara was named the Red Sox's closer. Since then, he has 42 saves in 44 chances in the regular season and postseason. In those 44 saves opportunities he has allowed just two earned runs.

"It's just about preparing every day, same way every day," Uehara said through a translator.

This season, Uehara is 15-for-15 in save chances, extending his streak to 31 straight regular-season saves. That's the longest active streak in the major leagues and second-longest in Red Sox history. Tom Gordon saved 54 straight for the Red Sox from April 19, 1998 through May 31, 1999, setting an American League record.

"Amazing," manager John Farrell said of Uehara's numbers as a closer. "When you can count the runs he's given up on one hand, pretty good."
