CHICAGO -- Rick Hahn has been adding veteran pitching options to the White Sox system since the end of March.
Frank Francisco has not allowed an earned run over four innings pitched and three games for Triple-A Charlotte. Javy Guerra has a 2.13 ERA over eight games, and Tommy Hanson threw five no-hit innings in his second start for the Knights, with a third start scheduled for Friday. This trio gives the White Sox options without having to give up anyone in return.
"Both Francisco and Hanson essentially had to go to extended [spring camp] to build up arm strength and now join the [Charlotte] club and are still sort of building up their in-season regimen," Hahn said. "Hanson has had two starts, and he's progressing really well.
"All three of those guys could very realistically be factors," Hahn said.
The White Sox 40-man roster sits at 40, meaning a corresponding move would be needed if one of these three eventually were added.
