PITTSBURGH — The Giants on Saturday dipped back into the waiver wire and added a former Rookie of the Month.
Yermín Mercedes, 29, was claimed by San Francisco after he was designated for assignment by the Chicago White Sox last week. To clear a spot on the 40-man roster, the Giants waived catcher Michael Papierski, whom they acquired in exchange for Mauricio Dubón after he was designated for assignment earlier this year.
Mercedes, who is mostly limited to designated hitter but can also play first base and catcher, started last season with hits in his first eight at-bats, setting an MLB record, and went on to post a batting line of .415/.455/.659 for the month.
Mercedes was named the American League Rookie of the Month for April 2021. Ever since, however, he has batted .196/.264/272 in limited major-league opportunities.
Mercedes clashed with Chicago manager Tony La Russa over baseball’s so-called unwritten rules, but he should have no such issues with the Giants organization, which has shown no qualms with running up the score.
La Russa last season called Mercedes “clueless” for homering off a position player during a blowout.
The Giants have a track record of success with players written off the by White Sox.
Carlos Rodón has proven a valuable free-agent pick up.
And Luis González was another waiver-wire pickup after Chicago designated him for assignment last August.
Rodón lowered his ERA this season to 2.88 with eight shutout innings Friday night and is second in the National League with 91 strikeouts.
A year and a month since Mercedes was named the top AL rookie for the month of April, González earned the same honor in the National League for his month of May.
Mercedes will report to Triple-A Sacramento.
