SAN FRANCISCO (CBS Sports) - Two days ago, Padres closer Heath Bell was claimed off revocable waivers by the San Francisco Giants. It's possible the Giants were looking for some bullpen insurance due to injuries to Brian Wilson and Sergio Romo, but it's also possible the Giants just didn't want any other playoff contenders to get a shot at Bell.

Regardless of the reason, it doesn't matter now. The Giants and Padres had until 1:00 p.m. ET Friday to agree on a trade, and it hasn't happened, according to Scott Miller of CBSSports.com. So Bell remains in San Diego.

Bell, 33, is set to be a free agent at the conclusion of this season. He's converted 35 of 39 save chances this season with a 2.55 ERA, 1.19 WHIP with 40 strikeouts in 53 innings.

It's entirely possible Bell does walk in free agency -- though the Padres plan to raise payroll and Bell said he'd take a hometown discount -- but he's not going anywhere via trade this season.
