The White Sox’ farm system isn’t exactly teeming with major-league-ready players or depth in certain areas, but they do have reason to feel good about their catching situation. Josh Phegley, 25, has turned some heads with a hot start for Class AAA Charlotte and is “probably the most major-league-ready [prospect] in terms of having an impact,’’ said assistant general manager Buddy Bell, the Sox’ former farm director. Through Wednesday, Phegley was hitting .333 with 10 home runs, 11 doubles and 28 RBI in 34 games. His OPS is 1.051. As important, the minor-league Gold Glove winner is already more than adequate defensively, Bell said. “Everybody is talking about Phegley right now,’’ Bell said. “Phegley is having a great year defensively and offensively. We’re really happy with his progress. He’s done a nice job.’’ The 5-10, 220-pounder was drafted in the first round (38th overall) by the Sox out of Indiana University in 2009. After being limited to 48 games in 2010 because of a rare autoimmune disorder that lowers platelet count, Phegley is fully healthy. The Sox put a premium on defense and handling pitchers for their catchers, and that’s why Tyler Flowers, 27, isn’t at risk of getting laid off from his job despite his .202 average and one home run in the last 35 days. This is Flowers’ first go at catching full-time in the majors, and the Sox are prepared to give him a long look. Phegley’s defense, while characterized by Baseball America as “unrefined,” is good enough to give the Sox assurances that as a Plan B, he’s solid if Flowers doesn’t measure up. “He’s really good; he’s comparable to Flowers,’’ Bell said. “They both throw well and block and have some energy. So we feel pretty good where we are defensively catching-wise. “His balance is good from a defensive standpoint and offensive standpoint.’’ The Sox want Phegley to play every day and develop with the rest of the young catchers in their system, so bringing him up as a backup to Flowers won’t happen. “Our catching is really good,’’ Bell said. “With Phegley, [Mike] Blanke [at Class AA Birmingham] and Kevan Smith [Class A Winston-Salem], I think our depth in catching is really an advantage for us. That’s always a position to be strong at, and we are. We feel really good about that, especially defensively.’’
