Entering play Wednesday, Miami's 11 starters had combined for a 4.93 ERA (25th in the majors) and a 1.40 WHIP (19th). They threw 675 innings, ahead of only the rebuilding Cincinnati Reds, and walked 278 batters, tied for sixth-worst. Tom Koehler, Jeff Locke, Justin Nicolino and Chris O'Grady are among those who have failed to stabilize the back end of the rotation due to ineffectiveness or injury or both. And Vance Worley has pitched a combined 8 1/3 innings in his past two starts, including a loss Tuesday.
