(UPDATE: Sung Min Kim tweets that Webster is headed to the KBO.)
In a somewhat surprising move, the Pirates have released starting pitcher Allen Webster. The Bucs just traded for Webster a few weeks ago, acquiring him from Arizona for cash considerations, and he figured to be a part of their starting pitching depth next season. As Tim Williams notes, the timing of the release could indicate that Webster is headed to play in Japan or Korea, although that's not yet certain. (The Bucs had enough spots on their 40-man roster to keep him.)
Webster has struggled in parts of three seasons with the Red Sox and Diamondbacks, and last year he also struggled at the Triple-A level, posting an 8.18 ERA in 15 starts at Reno. He also experienced a significant loss of velocity over his three big-league seasons. If the Pirates liked Webster, it was surely because they saw something they might have been able to fix. Now, however, it appears they won't get that chance.
