MLB Trade Rumors The Brewers announced they’ve acquired left-hander Kyle Lobstein from the Nationals in exchange for cash considerations. He’s been optioned to Triple-A Nashville. To create space on the 40-man roster, righty Ryan Weber was designated for assignment. Additionally, Milwaukee announced that infielder Daniel Robertson has passed through outright waivers. Washington selected Lobstein to the roster late last month, marking his first major league action in five years. The 31-year-old made three appearances totaling 1 1/3 innings before the Nats designated him for assignment last weekend. Prior to his promotion, Lobstein had spent the year with Triple-A Rochester, where he impressively tossed 21 1/3 innings of 1.69 ERA ball, striking out a lofty 29.8% of opposing hitters against an average 9.5% walk rate.
