Yan (1-1) took the loss Friday against the White Sox after allowing two runs on one hit and one walk over two-thirds of an inning. He did not record a strikeout.
Yan entered for the ninth inning of a 4-4 game, and after issuing a leadoff walk, he retired two batters quickly before things unraveled. Jake Rogers launched a two-run homer to center field to end the game. It was the first loss of the season for Yan, who saw his ERA climb to 4.26. The left-hander, who made his MLB debut earlier this month, has given up three runs in his first 6.1 innings of big-league work while posting a 7:6 K:BB.
