ST. LOUIS (AP) – The San Francisco Giants placed closer Tyler Walker on the 15-day disabled list Sunday, two days after he surrendered a four-run, ninth-inning lead.

The right-hander has inflammation in his throwing shoulder, the team said. The Giants called up right-hander Brian Cooper from Triple-A Fresno.

Walker entered Friday’s game against the Cardinals in the eighth inning with a 2-0 lead. He got the final out of the eighth, and the Giants extended the lead to 4-0 in the top of the ninth.

But Walker gave up a double to John Mabry, a single to So Taguchi, a three-run homer to Yadier Molina and a single to pinch-hitter John Rodriguez to open the ninth. The Cardinals eventually won the game with two outs on Jim Edmonds’ two-run double.

Walker is 3-4 with 4.86 earned run average and 22 saves. He became the Giants’ closer May 12.

Cooper was sent to Fresno Monday. In three appearances this season, including one start, he is 0-1 with a 1.80 ERA.
