Question on position eligibility

[Gus]

A guy in my Yahoo league has Kim as a reliever, since he's starting now it forces him to fill a relievers spot on the roster when he is pitching. Is there a minimum number of games a player has to play at a position to be eligible for the spot? I thought somewhere it was stated that once a batter plays a position for 15 games then they'll be eligible for the spot, wasn't sure of the pitching. Any help?????

Position players 15 Starts
Starters - 3 Starts
Relievers - 5 appearances in relief

From Yahoo....

At the beginning of the Fantasy Baseball season, Yahoo! Sports placed all players into positions based on information from official rosters. Some players appear in multiple position lists and are eligible to fill any of those positions.
If a position player makes 15 appearances at a new position during the season, he will become eligible to play that position in Yahoo! Sports Fantasy Baseball.

Pitchers need to make three starts to become eligible as a starter, and five relief appearances to qualify as a reliever.

Please note that players may not be eligible for all of the positions that are displayed on their Yahoo! Sports player profile.
