A polite request to the Oakland A’s: When you make the announcement on your plans for a new ballpark, an announcement you promised to deliver this year (I’m hearing August), don’t go all chintzy on the info.

Along with the location of your new ballyard, please include two other vital facts: When, and who.

Please tell us when the construction will begin and when the park will open. This info is important because team president Billy Beane recently announced that his roster-stockers have been instructed to stock the roster with young talent, so that these kids will be mature and ready to rip when you open your new park.

If the ballpark’s opening is six or seven years down the road, you have started your roster rebuild way too early, and fans might suspect you of using the newly announced youth movement as a flimsy excuse to keep payroll ridiculously low. You wouldn’t want fans to think that about you.

Also, please tell us who will pay for the new ballpark. Will it be current owner John Fisher, or the Next Owner Up? If it’s Fisher, please give us a for-dummies explanation of the financing, considering that Fisher’s personal wealth seems to be trending downward, due to a dip in Gap stock and the phasing-out of Fisher’s annual windfall from MLB revenue-sharing.

Last thought: We know you A’s folks wouldn’t do anything laughably insulting, like announcing that the team has narrowed its choice of potential sites to two or three locales.

Really looking forward to the announcement, A’s, and we’re still diggin’ the food trucks.

Deep thoughts, cheap shots

& bon mots ...

The hilarity continues in the Colin Kaepernick saga. Ravens’ owner Steve Bisciotti, speaking before a group of fans, said of the reports of team interest in Kaepernick, “Your opinions matter to us. ... We’re very sensitive to it, and we’re monitoring it, and we’re trying to figure out what’s the right tack. So pray for us.”

Pray for us? I’m no theologian, but if Ravens’ fans are devoting valuable prayer time to asking the Lord to guide this football team in its quest for a backup quarterback, your life and your world are in terrific shape.

The Ravens signed a backup QB from an indoor football league. “Hey, we’ve got some arms, what about us?” said the Ultimate Frisbee League.

Who’s the mystery ring seller? Reader Dwayne Newton forwards an online ad: “Pickup (sic) the greatest keepsake this Pro Football Hall of Fame weekend, a Super Bowl ring!! Past enshrinee bringing a former teammate to Canton this weekend.” Price: $35,000. It’s a ring from the ’82 Super Bowl (’81 season), the 49ers’ first Super Bowl win. I did some legwork for you. HOFers on that team: Joe Montana, Ronnie Lott, Fred Dean. The “past enshrinee” could also be Steve Young (joined team in ’87) or Jerry Rice (’85).

The Warriors’ widespread love of golf (Stephen Curry, Andre Iguodala, Steve Kerr, others) won’t do much to change the Dubs’ so-not-street image. Oh, well. As they say in basketball, “Scoreboard!”

Can anyone top this non-pro father-son power golf foursome? Del l and Stephen Curry, and Jerry and Jonnie West. Jerry West at one time held a non-competitive course record at Riviera Country Club in Los Angeles. Oddly, the four have never played together.

Fun fact: Scientists and statisticians say that on the opening day of NFL training camps every season, the total amount of weight lost by NFL players in the offseason exactly matches the total amount gained by other players.

The Cubs, apparently seeking some kind of closure, say they will present a World Series ring to Steve Bartman , the fan often blamed for the team’s 2003 playoff collapse after reaching for and deflecting a pop foul. Suggestion: In a special pregame ceremony, toss him the ring in the stands.

It must have been hard for A’s fans not to wince at Sonny Gray’s beaming reaction to his Escape from A’s-catraz. Can’t blame him. Some players would give their right arm to jump from the sloggin’ A’s to the glory-bound Yankees, but all Sonny had to give up was his scraggly beard.

Knucklehead of the Week

The Ravens

ESPN reported that Ravens GM Ozzie Newsome and coach John Harbaugh had “met resistance” from owner Steve Bisciotti about possibly signing Colin Kaepernick. Newsome said the report was “wrong” because Bisciotti “has not told us we cannot sign Colin Kaepernick, nor has he blocked the move.”

Thus, Newsome cleverly denied something that was not reported. “Resistance” is not the same thing as blocking.

Bisciotti confessed he is agonizingly conflicted over the potential impact of a Kaepernick signing. Which explains why the Ravens are doing more dancing than the cast of “Riverdance.”
