Berroa was recalled from Double-A Arkansas on Wednesday, Ryan Divish of The Seattle Times reports.
Berroa has offered a mixed bag this season at Arkansas, posting a 2.93 ERA with 69 strikeouts over 46 innings, but also 31 walks. Big strikeout totals and lots of free passes are nothing new for the hard-throwing right-hander, and the Mariners will be hoping the 23-year-old provides more of the former in his first big-league stint.
