Jeremy Guthrie (shoulder) tossed four scoreless innings Thursday in a minor league rehab game with High-A Modesto. Guthrie allowed only two hits while striking out four and walking just one. Barring any setbacks, he is expected to return to start Tuesday against the Giants. The 33-year-old right-hander had a 5.92 ERA over four starts prior to injuring his right shoulder in a bicycle accident two weeks ago.
