ESPN3 and ESPNDeportes normally broadcast at least one VZ or DR winter league game per week and old broadcasts are archived.
If you go to the Dominican league's website, and click on the "transmision" tab right below the site search box, there are links to live broadcasts. If you register for the site, you can access archived broadcasts through their "multimedia" section (apparently).
Ignacio Serrano has a nice blog on the LVBP.
Taylor Teagarden and Chris Davis will arrive in the Dominican together on Wednesday and be available to play for Estrellas as early as Friday.
Omar Beltre made his 2010 debut for the Toros del Este pitching a scoreless inning and will apparently be stretched out over his next few starts and plugged into the rotation. He was 92-94, getting zero swinging strikes while giving up some hard contact (single, deep AO to CF, shallow AO to CF, CS). Not sure if this is good news given his extensive injury history over the last 2 years (which began, not coincidentally, during winter ball 2008). As a refresher, let's just recount his injury history the last 2 years (see here and here): injured toward the end of his Dominican season in 2008; missed all but the last week in 2009; shut down again after only a few innings during the 2009 Dominican season; missed all of spring training with TX 2010. During his time with OKC in 2010, he was on and off the DL all season, moved between the rotation/bullpen - presumably in an attempt to manage his arm - and skipped over in at least one start due to shoulder stiffness.
If you buy the argument that pitching in relief is less stressful on the arm, then the likelihood that Beltre will put in a full season as a starter in 2011, either in the minors or the majors, remains highly doubtful. It would seem prudent (beginning even last year perhaps) to consider him a bullpen arm from here on out given his age and injury history, and it is a little puzzling that TX still thinks of him (turns 30 in August) as a starter. Beltre has never thrown more than 100 innings in his entire 10 year career, never. His innings totals from the last 5 years, 2006-2010: 96, 74, 50, 11, 92. Even if you consider that he was pitching in leagues with shorter seasons - the DSL and the Dominican - this still has to give one pause. Why take a chance?
