Losing Henderson Alvarez, even if it is just for a 15-day DL stint is a huge blow for the Miami Marlins. Without Jose Fernandez and with Mat Latos looking like a shell of himself, the team could be in major trouble.
A rotation of Mat Latos, Tom Koehler, Dan Haren, Jarred Cosart, and David Phelps is unlikely to put a fear into many lineups around the league. This quintet through the first 7 games for the Miami Marlins have combined for 23 2/3 innings of work, allowing 17 runs on 27 hits, while striking out just 13 and walking 13.
