Yan performed well after being called up in early August with three runs allowed in his first nine appearances, but he'll now head back to Syracuse after surrendering five earned runs in his past four outings. Tobias Myers will fill the open roster spot for the Mets.

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.
