What It Means:

Lewis was forced to leave Tuesday's game with a triceps injury, and he underwent an MRI on his on Wednesday. The results of the MRI have not been made public, but a trip to the disabled list is probably still not out of the question.

Lewis owns a 3.21 ERA, and he has been getting pretty lucky this season. He's fanning just 5.6 hitters per nine innings, and his .234 BABIP is a career-low mark. Lewis' 4.84 xFIP more accurately portrays how he's pitched. Our models project him to post a 3.96 ERA and 1.22 WHIP over 72 2/3 innings remaining this season.
