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.
That performance evidently intrigued the Milwaukee front office, which also has Brent Suter, Aaron Ashby, Hoby Milner and Angel Perdomo as left-handed options behind relief ace Josh Hader. Lobstein is in his final option year, so he can be shuttled between Milwaukee and Nashville for the remainder of the season if he sticks on the 40-man roster.
Milwaukee claimed Weber off waivers from the Red Sox a little more than a month ago. He’s made just one appearance with the Brewers, tossing a scoreless inning of relief against the Rockies. Weber has spent more of the year at Triple-A, pitching to a 5.02 ERA with an average 23.5% strikeout rate and a stingy 6% walk percentage over 43 frames split between Boston’s and Milwaukee’s affiliates. He’s appeared in the big leagues for five teams over the past seven seasons, compiling a 5.27 ERA/4.30 SIERA at the highest level. Milwaukee will have a week to trade Weber or place him on waivers.
The Brewers signed Robertson to a one-year, $900K deal over the offseason. The right-handed hitting utiltityman didn’t produce much in a limited look, though, hitting just .164/.303/.274 across 90 plate appearances before being designated for assignment last week. As a player with between three and five years of MLB service time, Robertson has the right to reject the outright assignment in favor of free agency. Doing so would mean forfeiting the remainder of his guaranteed salary, though, so he seems likelier to report to Nashville and hope to play his way back onto the big league roster before the end of the year.
