Lamb, 27, landed on the disabled list last week with what was described as a left shoulder contusion. It was later revealed that he had “fraying” in his left rotator cuff. Lamb hit a lackluster .222/.307/.348 with six home runs and 31 RBI in 238 plate appearances on the season.
The D-Backs recently acquired Eduardo Escobar from the Twins and have started him at third base in three out of the last four games. He figures to continue getting the lion’s share of playing time at the hot corner. Escobar is hitting .276/.339/.511 with 15 home runs and 65 RBI in 422 PA on the year.
