The Tigers signed Nate Robertson to a three-year, $21-million extension today. Robertson went 13-13 with a 3.84 ERA in 2006, but struggled with a "dead arm" last season and was 9-13 with a 4.76 ERA.
Robertson's 2007 was in line with his 2004 and 2005 seasons, which is a concern. Maybe he'll never be as good as 2006 again. But even if Robertson is no more than a decent No. 5 starter, the Tigers did well to sign him to this deal becaue they've got Robertson at below market value should he rebound. Robertson went 2-2 with a 3.76 ERA and 1.23 WHIP last September.
Robertson will be 30 this season and is left-handed.
