Hawksworth arrived at Citizens Bank Park in time for the finale of the three-game series against the Phillies and was available to pitch. Hawksworth was originally scheduled to start for the Redbirds on Sunday, but was a late scratch.
Kinney had a rough outing in Saturday's 14-6 loss to the Phillies. He allowed four hits and six earned runs in two-thirds of an inning, pushing his ERA to 10.95.
Cardinals manager Tony La Russa has said repeatedly how comfortable he would be to go with 13 pitchers during this grueling stretch of 17 games in 17 days. The Cardinals used four relief pitchers on Saturday and five on Sunday.
"The No. 1 thing we want to do is protect our relievers," La Russa said.
Hawksworth, who was selected in the 2001, signed in the spring of '02 and has been pitching in the Cardinals' Minor League system for about seven years. Healthy after a string of injuries over the past few years, he pitched very well in winter ball and has carried that momentum through this season.
In eight appearances with the Cardinals this season, Hawksworth allowed 13 hits and five runs (four earned), equaling a 3.00 ERA.
