The Giants face one contract option after the season. Shortstop Edgar Renteria has a $10.5MM club option with a $500K buyout. Even with a bounceback year, the Giants figure to decline. The Giants could re-sign Renteria at a lower price, or look at other free agents.
The Giants increased payroll by almost $14MM this year. They'd have $8-9MM to play with holding payroll steady, so maybe a smaller increase is in order for 2011.
Thanks to Cot's Baseball Contracts for the info.
