To make room for Anderson the Brewers placed left-hander Robert Gasser on the 60-day injured list. Gasser isn't expected to pitch until August at the earliest as he rehabs from Tommy John surgery.
The Brewers could use Anderson as either a starter or a reliever as they put together a pitching staff without All-Star closer Devin Williams (traded to the Yankees) and likely without starter Brandon Woodruff at the start of the season as he works back from shoulder surgery. Manager Pat Murphy also revealed Wednesday that left-hander DL Hall, a rotation candidate who could also fit in the bullpen, would remain shut down for several more weeks with a lat injury.
