Athletics option Jack Perkins and promote Joey Estes to major league roster

The Oakland Athletics moved pitcher Jack Perkins to Triple-A Las Vegas following his start on Thursday night against the Seattle Mariners. Perkins recorded 7 strikeouts but allowed 3 earned runs and 5 walks over 3 innings during the contest. Manager Mark Kotsay cited the need for bullpen length as the primary driver for promoting Joey Estes to the active roster. Perkins holds a 6.50 ERA this season, with his performance as a starter resulting in a 7.67 ERA compared to his 4.76 mark as a reliever. The team is currently navigating a series of injuries, including potential rotation vacancies that may require further roster adjustments. J.T. Ginn is scheduled for an evaluation with a team orthopedist on Saturday to determine his status for the remainder of the season.
