Astros notes: Wandy, Bogusevic, Astroline, and a couple of dancing Astros.

News, notes, photos and videos from Astros Spring Training Wednesday:

* There wasn’t a ton of intrigue surrounding the Opening Day announcement, considering Wandy Rodriguez was more or less on pace all spring to pitch on April 6. Still, manager Brad Mills made it official before the workout started Wednesday, naming Rodriguez, the longest tenured current Astro, as the Opening Day pitcher.

Left-handed Opening Day starters are a rarity for the Astros. In fact, Wandy is the first lefty to receive the honor since 1974, when Dave Roberts took the mound for the Astros’ opener.

* Brian Bogusevic struggled through much of Spring Training, but this week, he’s had a much better showing at the plate. His spot on the 25-man roster was never in jeopardy — everyone is anxious to see what he can do over a full season, now that he’s a couple of years removed from converting from a pitcher to an outfielder — but still, you could sense some frustration on his part as he worked to get his timing down at the plate.

This may be coincidental, but it should be noted Carlos Lee sat down with Bogusevic a few days ago and spent 45 minutes with him talking hitting. That was right around the time Bogusevic started having more success during games. So you never know.

* MLB Network was in town for two days filming footage for the Astros segment of its 30 Clubs in 30 Days series. The show will air at 7 CT/8 ET Wednesday night.

* At the exact same time, general manager Jeff Luhnow will be Milo Hamilton’s guest for the final Astroline of the offseason. The show will air on 740 KTRH and Astros.com. If you have questions for the GM, please tweet them to me.
