OAKLAND — The Giants received sad news about a beloved clubhouse mainstay. Longtime attendant David Loewenstein died Tuesday after a lengthy illness. He was 60.

Loewenstein, the stepson of former Giants GM Al Rosen, dealt with health challenges all his life, including Crohn’s disease and diabetes. But he seldom wavered from being a positive and joyful presence in players’ lives.

Former manager Dusty Baker would have Loewenstein get in front of the team before every pre-workout meeting in spring training and recite a quote of the day. David’s wordy, meandering explanations of the quote were the best part.

He also was known for singing “Happy Birthday” to players, and if they were from Latin America, “Feliz Cumpleaños” with the only four words of Spanish he knew. After either version, he’d follow with a shuffling dance that needed no translation.

And he didn’t mind stepping up in weight class to wrestle with players, an activity that nobody enjoyed more than former left-hander Steve Kline.

“He just loved keeping the guys loose,” Bochy said. “Just a beautiful person, and I’ll never forget what he said to me in 2010. It was after a loss and he said, `Aw, it’s all right. You know you’ll win the World Series this year.”

When they did, Loewenstein, whose nickname was “Rolo,” was in the midst of one of his frequent hospital stays. Then he received a phone call from his boss, clubhouse manager Mike Murphy, telling him that the players had voted Rolo a full share worth more than $300,000.

“Getting the share surprised me, you know why?” Loewenstein said in a 2011 interview with Yahoo Sports. “Because I wasn’t working when we won. And they still remembered. All those years meant something.”
