Andruw Jones played 1B at Las Vegas last night. Not sure what that means, but I’m guessing it means he’ll be an option to back up there if Joe wants to give James Loney a day off here or there and doesn’t want to go back to that musical chairs thing he did last week with Martin at 3B and Blake at 1B. The 51s committed four errors last night, but none of them were by Andruw. That’s a good sign. … The Dodgers are still somewhat in contention in the N.L. West, but it’s worth noting that they began the day tied with Houston for the eighth-best record in the bad National League, a loop that only has 16 teams. The Astros, by the way, were 14 games out in the Central. … Greg Miller, once the Dodgers’ top left-handed pitching prospect, might be getting close to the end of the line. There was a time earlier this season when he seemed to be coming out of his longstanding control problems, but he seems to have relapsed since his promotion to Las Vegas. He gave up four runs last night after walking three batters (and allowing NO hits) in one inning pitched at Colorado Springs. Since his promotion to Vegas, he has walked 46 batters in 28 2/3 innings, all while allowing just 19 hits. In his past three appearances, he has walked eight batters in 3 2/3 innings.
