Ken Roll has been in enough spring camps to appreciate the fun that can be had on a baseball field.

At 65, he’s a trainer with years of experience around players, and yesterday he was standing on the sidelines chatting with two other trainers while the Mariners played catch.

A throw got away, as throws do, and someone yelled ‘Heads up!’

Roll did what most of us would do in that situation – he ducked, tried to wheel around so his face wasn’t in the path of the all. Then he saw the ball go harmlessly by. Except, by then, he was off balance and staggering.

“I stayed up as long as I could,” Roll said. “I was going to go down and I knew it, but they say it took me about 10 seconds to go down.”

When he did, players went into near hysterics. Nearly 24 hours later, they were still having fun with Roll.

On the field near where he finally came to rest, uninjured, Ken Griffey Jr. lay splayed while a teammate taped an outline of his body. When completed, it resembled those chalk outlines at evidence scenes on television. They even taped in eyes, a nose and a frown.

Then came the re-enactment.

“Trainer down!” someone screamed.

Out of a crowd of players staggered Adrian Beltre, stumbling, wobbling and then collapsing hard directly into the taped outline. Players bent over they laughed so hard, and no one did so more than Roll.

“I’ve been in a lot of these camps, and I don’t think I’ve ever been in one where guys had more fun or got more instruction,” Roll said. “It’s good to hear guys enjoying themselves again.”

He came to spring training to make an impression, and with less than two weeks left in camp, two words describe Shawn Kelley.

Still here.

The morning after recording a 1-2-3 inning and his first Cactus League save, Kelley laughed at the question: Had he saved the baseball?

“No,” he said, laughing. “One of my strengths is staying with the plan, and the plan all spring has been to throw well. Sometimes I’ve thrown well and given up runs, sometimes I’ve thrown well and gotten good results.

“The only thing I can control is throwing well.”

With the Seattle bullpen still very much a work in progress, Kelley hasn’t so much worked his way into the Mariners plans as kept from pushed out of them. Two rounds of cuts, and Kelley’s status hasn’t changed.

Still here.

“Do I think about the possibilities? I try not to get ahead of myself,” he said. “When I get home at night and put my feet up, it’s definitely a good feeling to still be in big-league camp. But there are still a lot of arms here, and a lot of moves to be made.”

Kelley at 25 is a bit like Brandon Morrow was two years ago at 22. He shouldn’t have made the team, but his right arm kept throwing strikes – high 90s strikes – and eventually the Mariners took Morrow north.

Could it happen again?

“He’s been impressive, and not just the way he’s thrown,” manager Don Wakamatsu said. “His mound presence, his maturity, his thought process.”

No, the spring numbers aren’t overwhelming, but Kelley’s body of work over the last two seasons has been. In 61 minor league games, none higher than Class AA, he’s gone 5-2 with a 1.98 earned run average and 15 saves.

The clock is running, and Kelley remains a longshot to make the opening day roster.

But he’s still here.
