Right-hander Michael Kopech, who was a Red Sox first-round draft pick last year out of a Texas high school, has been suspended 50 games following a positive test for the stimulant Oxilofrine.
Selected with the 33rd overall pick the Red Sox received as compensation for losing Jacoby Ellsbury to the Yankees via free agency, Kopech was pitching for low Single-A Greenville with a 2.63 ERA and 70/27 K/BB ratio in 65 innings as a starter.
Kopech will miss the remainder of the minor-league season. He signed for a $1.5 million bonus.
The Athletic’s Jayson Stark reports that the Giants have signed 1B/OF Darin Ruf to a minor league contract.
Ruf, 33, played parts of five seasons in the majors with the Phillies from 2012-16, enjoying occasional offensive success. He spent the last three seasons in the KBO League in South Korea with the Samsung Lions, reigniting his career. Ruf hit an aggregate .313/.404/.564 with 86 home runs and 350 RBI over 1,756 plate appearances.
Ruf joins an ever-increasing list of players whose major league careers fizzled out, then found new life overseas — Eric Thames and Miles Mikolas are a couple of examples. Ruf will hope to prove himself as a big leaguer once more in spring training with the Giants.
