KANSAS CITY - Both baseball commissioner Bud Selig and Major League Baseball Players Association executive director Michael Weiner responded this afternoon from the site of tonight’s All-Star game to the new Bobby Valentine-produced documentary “Ballplayer: Pelotero,” which comes to the Coolidge Corner Theatre in Brookline for a preview Wednesday and opens there on Friday.

The documentary exposes some of the corruption associated with signing of Dominican players.

Weiner commented: “I have heard about it. I have met some of the filmmakers. There aren’t a lot of headlines that are going to come out of this, but that somebody has a problem with something Bobby Valentine did, that’s pretty big headlines. Seriously, I don’t think it’s Bobby’s involvement. They expose the types of practices … it’s not an easy thing for MLB to see and I know that it wasn’t a complimentary treatment of some of the facets of the way MLB has handled it down there.”

Said Selig: “I haven’t seen it. I’ve been told about it. I’m looking forward to seeing it. We spent a lot of time in the Dominican Republic and the people that are down there as well as those up here are satisfied we’ve made an enormous amount of progress. (Current Mets GM) Sandy Alderson went down there and did a tremendous job. We’ve replaced a lot of people. We thought there were parts of it, from what I’ve been told from those who watched it in the office, that it was inaccurate. And so I guess it’s been written so, and so I expressed our concerns to Red Sox ownership and that was it. What they did from there is up to them.

“And by the way they (Sox ownership) were concerned. They played an active role. They’re one of the many clubs who played a role in the Dominican and were anxious to clean that up and continue to work on it and I think we made enormous progress."

The biggest gripe from MLB is that the movie is outdated because so much of the corruption has been cleared up and the movie does not reflect those updates.
