Terry Ryan received word Monday that the Houston Astros' internal communications regarding possible trades had been leaked, or their database hacked, and published on the Internet. And he was thankful, he said, to learn no contact with the Twins had been included.

"There are some people whose feelings are going to be hurt today after they read their names," Ryan said. "I've certainly talked to the Houston Astros about various things, but I guess I went unscathed in this one."

Still, Ryan said, it was a reminder that some information needs to be kept confidential. "There's nothing worse than having somebody out there telling people what you're doing," he said. "It's certainly not advantageous for what I'm trying to accomplish."

General managers are in relatively frequent contact, Ryan said, by e-mail, phone calls, or text messages — the latter more so than ever these days. "A lot of us are traveling, and it's easy just to reach for your phone and text somebody," he said. "It's handy, but it's also a little dangerous, if people get ahold of your passwords. It's dangerous when you get too many people involved who don't really have a vested interest."

The Twins have discussed communications security internally, he said, but Ryan doubted that the team's systems or procedures will change because of the Astros' situation.

Remembering Castillo

Bobby Castillo specialized in throwing the screwball during his three seasons with the Twins, and that was appropriate.

"I'm not going to say that pitch described his personality, but maybe a portion of it," Tim Laudner, who caught 39 of Castillo's 77 games with the Twins from 1982 to '84, said of his former teammate. "He always had this look on his face like, 'I've got something that nobody else has, and you know I'm going to get you out with it.' So he kind of carried that smirk with him."

Castillo, who went 38-40 during a nine-year major league career, died of cancer Monday in Los Angeles. He was 59.

"That's so sad. It makes me sad to hear that, because he was always such a happy guy," Laudner said of the righthander known as "Bobo." He was 13-11 for the Twins in 1982, a career high in victories, after being acquired that January in a trade.

Castillo, who appeared in the 1981 World Series with the Dodgers, was credited with teaching Fernando Valenzuela his favorite pitch. "He was a really good competitor. He always had a smile on his face," Laudner said. "I know I enjoyed catching him."

Etc.

• Trevor Plouffe (rib) was in the starting lineup Monday along with Eduardo Nunez (hamstring) after both were activated from the disabled list. The two infielders replaced Pedro Florimon, sent back to Class AAA Rochester, and Jorge Polanco, who was returned to Class A Fort Myers after going 2-for-5 in his first four major league games.

• Shortstop Danny Santana's bruised knee isn't serious, Ryan said, and he should return once his 15-day DL stint expires July 11. In the meantime, manager Ron Gardenhire said, Chris Parmelee might get a few more starts in center field, where he has two appearances as a professional.

• Trevor May's calf injury, which has him on the seven-day disabled list at Class AAA Rochester, might actually be "a blessing," Ryan said, because it gives the righthanded starter a break from the midseason grind. Ryan said he expects May to recover in plenty of time to pitch in the Futures Game at Target Field on July 13.
