Diamondbacks' Oliver Perez: DFA'd by Arizona

Perez was designated for assignment by the Diamondbacks on Monday.

Perez made Arizona's Opening Day roster after signing as a non-roster invitee in March, but the club has seen enough after he surrendered seven earned runs over four innings to begin the year. The 40-year-old lefty could head to Triple-A Reno if he passes through waivers unclaimed or could opt for free agency.
