Uehara was on a tear, a streak to be more precise, and heading for record territory.
The Boston closer had mowed down every batter he faced. As the Boston Globe put it:
"Since July 9, he had retired 37 straight. It was like watching a pitcher throw a no-hitter (and then some) in one-inning episodes."
Koji was only four short of the record held by Bobby Jenks, when in 2007 he retired 41 straight batters. The Sox watched as Uehara gave up a triple to Orioles DH Danny Valencia.
Valenica eventually scored ending Uehara's streak of more than 30 scoreless innings.
The 38 year-old Japanese pitcher arrived in Boston in the off-season after spending three seasons with the Orioles and Texas Rangers where he was as starting pitcher.
He became the Sox closer after injuries took their toll and his reputation grew. So much so that he is the subject of a song that has been picked up by Boston's WEEI radio station.
Using the tune from an oldie but goodie rock 'n roll song, "Sea Cruise", the lyrics are an ode to Uehara. "Koji's On the Mound" seems to have come along at just the right time.
"Ueie, Uehara, Ueie, sit down battah' Ueie Ueie baby, Koji's on the mound and we can't lose," is the chorus.
Looking at the post-season possibilities with Koji Uehara coming in late looks mighty good to Red Sox fans. Sitting atop Major League Baseball with the best record, the Sox have run away with their division and are poised to set up their rotation for the first round of the playoffs.
Boston's magic number to clinch the division still stands at 2 after last night's loss to Baltimore.
