ARLINGTON -- The recovery process for Ramon Castro has taken a step forward, as the White Sox veteran backstop got the start for Triple-A Charlotte on Tuesday night. Castro was placed on the 15-day disabled list on April 4, retroactive to March 29, with a bruised right heel. Donny Lucy has received great praise for his solid job filling in for Castro, finishing 1-for-2 with a walk in Tuesday's 4-2 loss. Lucy also has the respect of the pitchers whom he catches. When Castro is healthy, the White Sox could have a tough call to make in regard to the reserve behind A.J. Pierzynski. "Every time you make a call, it's a tough call. You don't want to do that, but right now I'm very excited about Lucy," Ozzie Guillen said. "I think Castro has to come here 100 percent ready because the guy here is playing very well.
"We're not in a hurry or desperate to call him up. I'm very excited about Lucy and we'll see when the time comes." Guillen added that White Sox athletic trainer Herm Schneider didn't give a set timetable for the return of Castro, who will earn $1 million this season with a club option of $1.2 million in 2011. Castro started his rehab assignment, which can last up until 20 days, with two hits and a two-run home run for the Knights. "[Castro] has got to catch a couple games out there," Guillen said. "A couple innings to see how he feels and I think maybe someone from the Minor Leagues will watch him or somebody from the pro front office will watch him and see how he's doing."
