The St. Louis Cardinals announced Tuesday the signing of starting pitcher Jake Westbrook to a contract extension through 2013 with a mutual option for the 2014 season. Terms of the extension were not immediately released.
Westbrook had a mutual option for the 2013 season, based off a two-year, $16.5 million extension he signed with the club in 2010. The mutual option was worth $8.5 million for 2013 with a $1 million buyout.
Westbrook, who will turn 35 in September, is 12-9 on the season. He's won five of his last six decisions, dropping his ERA to 3.50. He allowed one earned run and six hits in 7.2 innings of work in a duel against Pittsburgh Pirates starter James McDonald in his last start.
