Jeff Niemann, out since mid-May with a fractured leg, allowed four runs in 3 1/3 innings in his second rehab start for high-A Charlotte on Tuesday. He’s still probably two rehab starts away from rejoining the Rays, but his return could prompt a roster crunch.
Alex Cobb, Niemann’s rotation replacement, has won his last three starts, allowing exactly one run in seven innings each time. He was struggling some beforehand, but he has pitched better than his 7-8 record and 4.08 ERA overall. In 90 1/3 innings, he’s allowed just four homers and posted a 67/26 K/BB ratio.
Niemann had a 3.38 ERA before going down, so he doesn’t deserve to lose his spot. Still, the Rays could consider taking a look at him in a relief role. After all, he doesn’t project as a member of their playoff rotation, should they make it. The Rays have a top four of David Price, James Shields, Matt Moore and Jeremy Hellickson to use in October, so giving Niemann a head start on pitching out of the pen might be for the best.
