The Milwaukee Brewers will have to make a change in their starting rotation this week after announcing that Shaun Marcum will be scratched from his scheduled start on Tuesday against the Toronto Blue Jays, because of a “tight elbow.”

Marcum, who was traded to the Brewers from the Blue Jays in December of 2010 for third baseman Brett Lawrie, struggled in the post season last year, but has looked great so far in 2012. He has started 13 games, compiling a 3.39 ERA, 3.81 FIP and 3.89 xFIP while striking out 22.5% of the batter’s he’s faced.

The Brewers will most likely call up a starting pitcher from Triple A to replace Marcum in the rotation. However, they might also consider spot starting Manny Parra or Kameron Loe. Going with a bullpen start on Tuesday seems unlikely given the team’s taxing 15 inning game in Minnesota on Sunday.
