Marquez is coming off his worst start of the season -- and it was in Wrigley Field against the Cubs last week when he gave up eight earned runs in 5 1/3 innings. Darvish is in the second year of the sizeable free agent contract he signed. So far he is 3-6 in 106 1/3 innings in a Cubs' uniform -- far below the expectations.

Both starters faced the opposition last week in Chicago. Marquez suffered the loss in that game. Darvish had a no-decision.
