ST. LOUIS (AP) — Cardinals right-hander Michael Wacha was placed on the 10-day injured list because of patellar tendinitis in his left knee and will miss his scheduled start Tuesday against NL Central rival Milwaukee.

St. Louis said the move was retroactive to Friday. Infielder/outfielder Drew Robinson was recalled Monday from Triple-A Memphis.

Wacha is sidelined for the fourth time in six years. He was 8-2 in 15 starts last year but did not pitch for the Cardinals after June 20 because of a strained oblique muscle in his left side.

Wacha was on the disabled list from June 14 to Sept. 3, 2014, with a right shoulder stress reaction and from Aug. 9 to Sept. 13, 2016, with right shoulder inflammation.

He is 1-0 with a 4.64 ERA in four starts this season. He beat Milwaukee 6-3 last week, allowing two runs in six innings.

Robinson played four games with St. Louis this season, in center field, and was 0 for 6.
