"As long as nothing goes crazy from today and tomorrow," Guillen said. "But he's starting the second game in Baltimore."
The April 28 game between the White Sox and Orioles was suspended after 11 innings and will be completed Monday as well. Guillen has not yet announced who will come in to start that game.
Richard's placement in the rotation is not an indication that he will now be a permanent member of the staff, however. Guillen said the White Sox will use a four-man rotation and adjust it as necessary, with Richard otherwise working out of the bullpen.
"We'll try to put the best boys out there," Guillen said. "We'll be bumping here and there, but we'll have four guys working on regular days. I never like to do it, but this time I have to."
In other words, when the White Sox have an off-day that will allow a four-man rotation to work on regular rest, Richard will not be in Guillen's starting plans.
Richard has made four starts, but the only win came Tuesday. In his previous three starts, he'd posted a 10.38 ERA over 13 innings.
Guillen will perhaps have a few more pitching options if Dewayne Wise should land on the disabled list. The center fielder left Wednesday's game against Seattle with a strained left adductor, and will be evaluated Sunday.
If Wise does end up on the DL, Guillen said the team will certainly bring up a pitcher to take some of the load off an overworked bullpen.
"If we make that decision, it's gonna be a pitcher," Guillen said. "I'm running short the last two, three weeks, and if we [are] gonna do that I'll need another arm."
