This is not good. Lance has, indeed, been placed on the DL, and Edwin Maysonet has been called up to take his roster spot.
"It's for the best. I want to be on the field, so I'm not happy about it, but it's for the best. I look forward to getting it right and getting back on the field in a couple of weeks. It's better to be out a couple of weeks than a couple of months."
"I spoke with Dr. Lintner today, and we are in agreement that keeping Lance active will only put him in a position of wanting to help the club and reaggravating the injury. I also spoke to Lance, and he understands. It's not easy to disable one of your key guys, but we want him strong for the stretch drive, so it's the right move."
There's no mention of a retroactive date, so he should be activated August 7 vs. Milwaukee. He'll miss series' against the Mets, Cubs, Cardinals, and Giants.
Here's your infield until that point:
1B: Coste (Erstad's still on the DL. So, good pickup of Coste by Wade)
2B: Matsui, Maysonet
3B: Blum, Keppinger
Richard Justice points out that, since the All-Star Break, the Astros are 5-2, and Lance only had 9PAs. The early part of the second half was tough, but it just got a little tougher.
