Jonathan Sanchez, the primary player involved in the trade that sent Melky Cabrera to the Giants, has done little for the Kansas City Royals, so the Royals essentially replaced him on the roster with the minor-league player acquired in the Cabrera trade -- Ryan Verdugo.
Verdugo was scheduled to make his major-league debut Tuesday.
Sanchez has been designated for assignment after another disappointing outing on Monday, when he gave up five runs before retiring a Mariners batter and yielded seven runs in 1 1/3 innings.
Sanchez is 1-6 with a 7.76 ERA in 12 starts, and he's winless in 11 starts after an April 8 victory over the Angels.
Meanwhile, Cabrera was a starter in the All-Star Game, so the trade does not look good at the moment.
But the throw-in in the trade was Verdugo, a left-hander who was recalled from Class AAA Omaha Tuesday.
He was 6-2 with a 3.58 ERA with Omaha and was selected to the Pacific Coast League All-Star team. He was scheduled to start Tuesday night against the Mariners.
The Royals also recalled right-handed pitcher Vin Mazzaro from Class AAA Omaha, and optioned outfielder Jason Bourgeois to Class AAA Omaha. Bourgeois hit .333 in 19 games with three extra-base hits.
