Monasterio started at shortstop and went 2-for-4 in Monday's 3-1 win over Kansas City.
Monasterio made a fourth consecutive start at shortstop as a fill-in for Trevor Story (groin), who could be facing surgery. The Red Sox have a few options to deploy at shortstop, but thus far interim manager Chad Tracy has only used Monasterio. He's slashing .256/.301/.397 with eight doubles, one home run, nine RBI and eight runs scored over 83 plate appearances.
