It could end up being a big signing for them come 2013.
After a strong couple of months to close the 2012 season with the Phils, Frandsen agreed Tuesday to a one-year, $850,000 contract to avoid salary arbitration. The deal includes incentives and performance bonuses.
Left-hander Antonio Bastardo and outfielder Nate Schierholtz are the team's only other remaining players eligible for arbitration.
Frandsen's signing is noteworthy because he could see significant playing time next season at third base along with Freddy Galvis. Placido Polanco will not be back next season, and the crop of free-agent third basemen is remarkably thin, so the Phillies might try to upgrade in the outfield and hope Frandsen and Galvis can handle the load.
Frandsen hit well with the Phils. He compiled a .338 average with 10 doubles, three triples, two home runs, 14 RBIs and an .834 on-base-plus-slugging percentage in 55 games. In 228 career games before last season, Frandsen hit just .243 with a .636 OPS.
