Jeff Niemann (fibula) will throw about 60 pitches in his second minor league rehab start Tuesday. If it goes well, Niemann might only have to make one more rehab appearance before rejoining the Tampa Bay rotation. He has been out since mid-May with a broken fibula. The 6-foot-9 right-hander had a 3.37 ERA and 1.18 WHIP in seven starts before going down.
