The Red Sox have until Monday afternoon to work out a deal with the Angels for Napoli, but it's unlikely the deal will get done, the source said. The Red Sox may have put in the claim to block another team from acquiring Napoli.
The right-handed hitting Napoli, who has seen significant time at first this season with Kendry Morales injured, is batting .249 with 21 homers and 60 RBIs in 113 games. He has about $720,000 remaining on a one-year, $3.6 million contract.
