At 27 years old, it's probably not appropriate to call Seibel a "prospect" any more, but he's having a very good season and is, perhaps, working his way back to being in the Major League mix.

You may remember Seibel as a guy with a World Series ring for his 3.2 innings worth of work with the 2004 Red Sox. They had claimed him off waivers from the Mets the previous offseason, and brought him up for two appearances in April.

The left-hander, a former 8th-round draft pick of the Expos, missed all of last year after undergoing Tommy John surgery, but the Red Sox stuck with him. After 4 good starts in Low-A with Greenville (2-0 with a 1.35 ERA), he got bumped up to AA Portland in late April, where his success has continued.

Seibel threw 5 shutout innings in Portland's win yesterday, bringing his AA stats to:

W-L: 1-3
IP: 30
ERA: 1.80
H: 19
Runs: 11
ER: 6
BB: 9
K: 27
HR: 5
WHIP: 0.93

Don't be surprised to see him in the Pawtucket rotation later this year.

Seibel was named Eastern League Pitcher of the Week after throwing 10 more shutout innings over two starts last week.

For the season at AA, Seibel has a 1.35 ERA in 40 IP. He's allowed only 21 hits, and has walked 12 while striking out 34.

Recurring arm problems have forced Seibel to the bullpen, perhaps for the rest of his career. He has been moved up to Pawtucket, however, and has pitched well in two outings (4 IP, 0 ER, 7 Ks) since his promotion.
