Jason Hammel was sent back down to AAA Durham after the D-Rays victory over the Royals on Sunday. Hammel looked impressive at times but made a few too many mistakes in his first two major league starts. Mark Hendrickson was scheduled to pitch during an extended spring training game on Monday, but that was postponed and he will only conduct long-toss exercises. This means that Hendrickson will not be ready to pitch next Saturday in Texas against the Rangers. The team has not announced who will replace Hammel in the rotation. The most likely candidate is Edwin Jackson. Jackson, who was impressive at times during spring training, is likely to pitch tonight for Durham. That would put him on schedule to pitch next Saturday with a normal four days rest. In two starts in Durham, Jackson has thrown 10 innings, giving up 7 hits, 6 walks, 3 earned runs, to the tune of a 2.70 era, while striking out 8. The D-Rays could also go with either Jamie Shields or Chris Seddon, both of whom have been impressive in their first two starts this season. Shields has pitched 11 innings giving up 14 hits, with no walks and 13 strikeouts and a 0.82 era. Seddon has pitched 11 innings giving up 7 hits, four walks and striking out 8 with a 0.82 era. Both pitchers are scheduled to pitch for Durham later this week and would not be ready for Saturday’s start in Texas unless the team decided to skip their normal turn in the rotation.
