Guo does his Mark Hendrickson imitation

and pitches lights out in his second rehab start at Triple-A Las Vegas.

From Yahoo Sports

The left-hander struck out seven batters in 2 1-3 innings against Sacramento, giving up a pair of singles. He also hit a batter, but used a fastball clocked at 94 mph and a sharp slider in striking out all seven batters he retired. "I was just trying to get outs today," [Guo] said. "I was lucky to get that many strikeouts. I feel healthy and was glad I could throw my slider for strikes."

When Guo becomes ready to join the Dodgers rotation, which pitcher would be the odd man out. Lowe and Penny are both healthy. Mark Hendrickson has been pitching lights out. Tomko has been decent, and Randy Wolf has had his ups and downs. Best bet is Tomko or Wolf get displaced or Hendrickson comes down to earth. The bullpen is also becoming crowded, as Brazoban will be ready shortly to rejoin the team. Could there be a trade in the works? Only time will tell.
