Farhan Zaidi knows how to flip an asset. Sometimes, it doesn’t take long.
That was certainly the case with veteran reliever Trevor Rosenthal, who was traded by the Giants after being acquired as a free agent 12 days ago. San Francisco sent Rosenthal to the Brewers in exchange for outfield prospect Tristian Peters ahead of Tuesday’s trade deadline.
Peters, 22, was just promoted to the Brewers Double-A affiliate and was rated as their No. 19 prospect by MLB Pipeline this season. Peters posted a .871 OPS at Single-A before his promotion.
A left-handed hitter, Peters is considered a contact guy with good athleticism. His below-average arm, however, projects that he will be a corner outfielder if he makes it to the big leagues.
The eight-year veteran Rosenthal, 32, signed a one-year deal at a rate of $4.5 million after not pitching in MLB since 2020 due to various injuries.
Rosenthal has 132 career saves and a lifetime 3.36 ERA. He spent the bulk of his career with the Cardinals, but has also pitched for the Padres, Royals, Nationals and Tigers.
Rosenthal was an All-Star 2015, when he recorded 48 saves and posted a 2.10 ERA with the Cardinals. He signed a one-year deal with the Athletics to be their closer for 2021, but didn’t throw a pitch for them.
