The fading Indians have told teams that they may trade opening day starter Justin Masterson, sources say.

Both the Red Sox and Rangers sent scouts to watch Masterson Saturday night in Minnesota, but he did not pitch well. After shutting out the Twins for the first three innings, Masterson allowed 10 runs (eight earned) over the next 2 2/3, to raise his ERA to 4.47.

The Indians have also fielded calls about right fielder Shin-Soo Choo (the Pirates have shown interest) and closer Chris Perez, but it appears doubtful that Perez will be moved.

The Indians were swept by the Twins over the weekend, falling to two games under .500 and six games behind the first-place White Sox in the American League Central.
