Mike Done refers to his whirlwind trip through the Orioles' minor league system as his "world tour."

After starting the season at Class A Delmarva, Done spent a week in AAA Ottawa as a fill-in on the Lynx roster, then another week at AA Bowie for a similar role before settling in as a regular at more advanced A Frederick.

"It was a great experience," Done said of his travels. "I got to go to a lot of places, and I really learned a lot from the other guys."

Done, who got off to a slow start at Delmarva, has felt right at home in Frederick. In 17 games, Done has been one of the Keys' hottest players, batting .328 with 13 RBI. On Sunday, he sparked Frederick's biggest win of the season, a 14-2 win over Lynchburg, with three hits and three RBI.

As the "world tour" showed, Done has followed an atypical path in a sport in which most players leave college after their junior year. Done was a 40th-round draft pick in 2001 out of the University of Washington after his senior year, but he stayed for a fifth year at Washington to graduate before signing with the Orioles in June 2002.

In two years with the organization, Done has made the most of his opportunities. He batted .318 at rookie-level Bluefield in 2002, and in 2003 he was picked for the South Atlantic League all-star game while at Delmarva.

Now 25, Done has 10 hits, 10 RBI and 5 runs scored in his last 28 at-bats. Already trained defensively at second and third base, Done is learning first base at Frederick.

"It is [a different experience] because I need to prove myself more quickly," Done said.

"Being older, they're going to see if I can play or not and then get rid of me, whereas a younger guy will get a few more chances to prove himself."
