Brewers manager Ron Roenicke said Tuesday that the Brewers have had "a lot of discussions" about promoting Jimmy Nelson. "There's been a lot (of discussions)," Roenicke. "We'll have to see, but there have been a lot of discussions. When the timing is right, you do it. We'll see." Nelson has a 22-inning scoreless streak at Triple-A Nashville and boasts a 1.46 ERA and 114/32 K/BB ratio over 111 innings. When asked whether Marco Estrada -- who would surely be the guy Nelson replaced in the rotation -- had a secure spot in the starting five, Roenicke said, "We'll see; we'll see on that."
