What’s going on with the Giants’ fancy new scoreboard?

The Giants have spent $10 million to replace the scoreboard at Oracle Park with a fancy new version, three times the size of its predecessor.

The new video board is 153 feet wide and 70 feet high, with a resolution twice as sharp as the previous scoreboard, which had become the second-oldest in baseball, believe it or not.

It all sounds great, except for one thing: it’s not done yet.

The season opens next week, but it’s not time to panic, say Giants officials, who are are confident the new board will be ready by the home opener on April 5.

That seems to be cutting things a little close.

(If you want to read more about the scoreboard, The Chronicle’s Henry Schulman wrote about it back in January.)

A visit to the park this past Friday revealed a frame of a scoreboard, but nothing close to a complete product. For Monday’s Bay Bridge Series game against the A’s, Giants brass says they will have a working version constructed.

“When we play baseball on Monday, it will not be in its final form,” said Giants Executive VP Alfonso Felder, but . “it will probably be two times the size of the board we had last year. That’ll allow us to really unveil the full impact of that board on Opening Day.”

When it is finally finished, the Mitsubishi Electronic Diamond Vision board will represent the “largest single capital improvement (to the stadium) since 2000,” said Felder. The 4K board should allow the team to display enhanced graphics.

“We’ll be working with a two-thirds version, or thereabouts, on Monday. I think it’ll be fun to see that evolution over the next couple of weeks,” said Felder at a media session Friday.

“It’s going to be able to show stats we’ve never shown. Video content that’s really going to enliven the in-game experience. We’re just excited about it.”

At Monday night’s rain-delayed game, the video board had grown to about two-thirds of its eventual size.

The board is part of a larger, five-year capital improvement plan aimed to be done by the time Oracle Park celebrates its 25th birthday in 2025.

“It’s hard to believe we’re almost 20 years into this building, but we are,” said Felder. “At that 25-year mark, we want this building to stand the test of time. We want it to be better than it was the day we opened. I think we’re really on track to do that.”

They grow up so fast.
