(AP) -- The St. Louis Cardinals' rotation has the best ERA in baseball, and it's about to get back the pitcher who had quite a bit to do with that for the first five weeks of the season.
Jake Westbrook makes his first start in more than a month Friday night as the NL Central leaders visit the Miami Marlins for the first of three.
Adam Wainwright lowered the St. Louis' starters ERA to 2.74 by throwing seven shutout innings in Thursday's 2-1 win at the New York Mets. Now, the Cardinals (43-23) are hoping Westbrook (2-1, 1.62 ERA) can seamlessly return to the rotation Friday after spending a month on the disabled list with right elbow inflammation.
The right-hander had a 1.62 ERA through six starts prior to the injury, the best mark in the Cardinals' rotation and one of the best in the majors. Though his peripheral numbers aren't impressive - Westbrook struck out 19 and walked 18 in 39.0 innings - he didn't allow a homer and had a major league-best 76.5 percent ground-ball rate.
