Here's what the Giants took away from Coors Field in three eventful days a mile high:

-- Never feel comfortable with a one-run lead in the ninth inning.

-- Always have plenty of relievers.

-- Pack a tornado survival kit.

Thursday's series finale was suspended in the bottom of the sixth inning after two rain delays lasting 2 hours, 46 minutes and it'll be resumed - with the score 2-2, two outs and Michael Cuddyer on first base - when the Giants return here in early September.

During their visit, the Giants lost a heartbreaker in the opener (closer Sergio Romo blowing a 4-3 lead) and two key pitchers in the second game, Matt Cain and Santiago Casilla, to hamstring injuries. Despite Wednesday's 5-1 victory, the mood wasn't great heading home for Friday night's game against the Twins.

"Pretty big blow for our bullpen," Tim Hudson said of losing Casilla, who's expected to miss four weeks.

For the second straight game, a Giants starting pitcher lasted just three innings. A day after Cain's early exit, Hudson's stint was shortened because of the first delay - which included a tornado warning that had fans taking cover - setting up more overtime for the relievers.

But the suspension gave the bullpen a break. The second delay was 1:24, and crew chief Bill Miller said another storm was on the way and an extra 45 minutes would have been needed to prepare the field.

"It just made sense to come back" in September, said manager Bruce Bochy, in no mood to risk more injuries. "This is the smartest thing to do, I believe."

All of Thursday's stats count, so Hunter Pence has five homers and Hudson has a 2.13 ERA after giving up one run - not bad considering it came on five hits and two walks. Not long into the first delay (lasting 1:22), Bochy decided Hudson, who had missed his previous start with a strained hip, was done.

He remains winless in seven career starts at Coors Field.

"Still on my bucket list," he said.

When the tornado warning was lifted and the storm passed, play resumed and Pence displayed one of the goofiest home run swings on record, moving his body seemingly all the wrong ways. But the ball carried over the right-field wall.
