SAN FRANCISCO -- Baseball players, young and old, like to tell stories, and in that respect, Padres advance scout Gregg Olson is no different.

But Olson, in his fourth year with the organization, has found a new audience for his stories and those of his peers by becoming an author.

"I was on the celebrity-golf tour for a few years between baseball and when I started scouting," Olson said. "I was at one of the events, we were all sitting around telling stories like athletes do and one of the wives said, 'They're very funny, someone should write these down.'"

So that's what Olson -- a veteran of 14 Major League seasons and the 1989 Rookie of the Year as closer with the Orioles -- went out and did.

Olson and his co-author Ocean Palmer penned "We Got to Play Baseball: 60 Stories from Men Who Played the Game."

"I looked at my phone list and looked at the names of guys I had and didn't think it would be too hard to put together some stories," Olson said on Tuesday from Miami, where he was scouting for the Padres' upcoming series with the Marlins. "It was a lot of fun to do, listening to them go on and on."

Olson said only two people declined to be interviewed. Collecting stories was the least of his problems.

"I prefaced the conversation with that they have 24 hours think of your favorite baseball story and keep it reasonably clean and I would check back the next day," Olson said. "... I didn't want to throw anyone under the bus. I wanted it clean because I knew my kids would read it."

Olson, who has a handful of his own stories included in the book, said that he would consider writing at least one more. He said his computer is brimming with stories waiting to see the light of day.

"I'm very happy with the product. The feedback has been great," Olson said. "I have at least another 90 stories on my computer. My co-author has picked his favorite 30, I picked my favorite 30. I've probably got another book right there on my computer."

As for his day job, Olson works his way around the National League to see future Padres opponents so he can pass along the latest information.

"They just turn me loose and I talk to [manager] Bud Black on the phone the first day of each series and give him my report," Olson said.

Amarista OK after injuring thumb

SAN FRANCISCO -- Padres infielder Alexi Amarista, who left Monday's 7-1 loss to the Giants with a jammed left thumb, was not in the starting lineup on Tuesday.

There's a chance that Amarista, a left-handed hitter, would not have played against Giants left-handed starter Madison Bumgarner anyway, but the real news was that Amarista's thumb felt better and that it didn't require an MRI.

Amarista hurt his thumb sliding headfirst while stealing second base in the fifth inning. He didn't hook the thumb on the bag, but instead injured it when his left hand initially hit the ground.

"He's doing fine. ... We think we dodged a bullet there," said Padres manager Bud Black. "He's doing much better."

Amarista, who can play all three outfield positions as well as second base, third base and shortstop, is hitting .360 with a .380 on-base percentage since June 19. He's hit safely in 19 of his past 21 games.

Injured prospects Kelly, Erlin making progress

SAN FRANCISCO -- Two highly regarded Padres pitching prospects appear to be on their way to making significant inroads in their recoveries from injuries.

Right-hander Casey Kelly, who is regarded as the Padres' top prospect by MLB.com, allowed four earned runs on six hits in two innings for the Padres' entry in the Arizona League on Monday. He struck out three and didn't issue a walk.

Kelly has been on the disabled list since April with a strained right elbow ligament. His outing Monday was the first time that he's pitched in a game since April, when he was pitching with Triple-A Tucson.

Kelly -- who had a 2.25 ERA in two starts with Tucson before the injury -- will pitch again on Saturday in Arizona.

Erlin, a left-handed pitcher who is regarded as the Padres' sixth-best prospect, has been sidelined since May with tendinitis in his elbow. He threw live batting practice on Tuesday and will do so again Friday. Erlin was 2-1 with a 2.67 ERA in seven starts before going on the DL.

Short hops

• The Padres announced their rotation for the three-game series in Miami beginning Friday. Kip Wells will start Friday, Ross Ohlendorf on Saturday and Clayton Richard on Sunday.

Former Padres pitcher Wade LeBlanc will pitch Saturday for the Marlins. The Padres traded LeBlanc last winter for catcher John Baker.
