From Today's Boston Globe:
Charlie Zink: Should the Red Sox replace one knuckleballer with another? The 28-year-old Zink, who has never pitched in the majors, is 13-4 with a 2.89 ERA for the Triple-A PawSox. Batters are hitting .228 against him. However, Zink started on Friday, which would make it a tough turnaround to be ready to pitch again on Tuesday, even for a knuckleballer. Still, don't count it out. The Providence Journal reported today that the Red Sox are leaning toward Zink.
Justin Masterson: After moving him to the bullpen from the rotation, it seems unlikely the Red Sox will change course and make him a starter again. However, you can expect the fans to make this option No. 1 for the Sox. Masterson has been unscored upon in his last four appearances out of the pen, including a 2 2/3-inning outing Sunday. Before moving to the bullpen, the 23-year-old Masterson was 4-3 with a 3.67 ERA in 9 starts with the Red Sox.
Michael Bowden: Slated to pitch for the Triple-A PawSox on Monday, the 21-year-old Bowden is the sexiest name on the list, if only because he's an unknown commodity that has excelled in the minors. Between Double- and Triple-A, Bowden is 9-6 with a 2.64 ERA this season with 115 strikeouts and just 27 walks in 126 innings. He is 0-2 with a 4.15 ERA in four starts with the PawSox
Devern Hansack: He's scheduled to pitch Tuesday for the Triple-A PawSox, so the timing is certainly right. Hansack has a respectable 4.10 ERA for the PawSox this season, but has a 5-10 record. He has a 2.45 ERA in his last 10 starts, but has given up at least three runs in each of his last three starts. In five career appearances with the Red Sox, Hansack has a 3.57 ERA.
David Pauley: Another unlikely option for Tuesday (he pitched on Saturday), Pauley is having a great season in Pawtucket. He is 13-4 with a 3.32 ERA. However, he has struggled at the major league level. In four career starts for the Red Sox, he is 0-2 with an 8.41 ERA.
Bartolo Colon: Remember him? In Pawtucket rehabbing from a back injury that landed him on the disabled list in mid-June, Colon pitched three shutout innings for Triple-A Pawtucket on Sunday, a big improvement over his previous outing, in which he surrendered three runs in just two-thirds of an inning. It appears the Red Sox don't have any intentions of rushing him back to the big club (MLB.com's Ian Browne reports that he will make at least a couple more starts before returning to the majors), but might Wake's injury prompt them to reconsider? Even if they did, he would definitely not be available to take Tuesday's turn in the rotation. A former Cy Young winner, Colon is 4-2 with a 4.09 ERA for the Red Sox this season.
