Lightning Round: Red Robin Gourmet Burgers, 3D Systems, Flowserve and More

Red Robin Gourmet Burgers (RRGB): This stock is "not a bad idea," Jim Cramer said. "Go for it."

3D Systems (DDD): To Cramer, there's just too much competition in the 3D space.

Flowserve (FLS): This is a good business, Cramer said.

Generac (GNRC): When it comes to generator makers, Cramer currently prefers Briggs & Stratton (BGG).

The Mosaic (MOS): The crop complex is probably going down, Cramer said, adding he's not interested in fertilizer plays right now.

Sempra Energy (SRE): "Buy, buy, buy!"

Phillips 66 (PSX): Go with Valero Energy (VLO) instead, Cramer said.
