On the same day that Josh Johnson rejoined the team, Marlins' manager Fredi Gonzalez had to field questions about Dontrelle Willis, who threw Friday and will throw again today to test a sore left forearm. ''It's just a little sore,'' said Willis, who sustained the injury while covering first base Thursday night, when Cleveland's Grady Sizemore accidentally kicked Willis' hand. Willis said his hand was fine, but the effect was on his forearm. Willis said he planned on making his next start, and Gonzalez didn't appear to be worried. ''I don't think it's anything major, nothing to be overly concerned about,'' he said.
