SAN FRANCISCO — Reliever Tony Sipp pitched in 36 games for the Washington Nationals this season, compiled a 4.71 ERA and at times looked like the left-handed specialist they signed him to be in March. But the 36-year-old’s short run with the organization came to a quiet end.
Sipp was designated for assignment by the Nationals last week as the team made room for three new relievers acquired at the trade deadline. He was then placed on outright waivers for three days, was not claimed by a team and was offered a minor league assignment by Washington. He rejected that offer, according to a person with knowledge of the situation, and will go on release waivers. If he clears those, too, Sipp will be a free agent this week.
