Herrera was sent back to Double-A Trenton on Friday, Brendan Kuty of NJ.com reports.
Herrera made just one appearance with the Yankees before being shuttled back to the minors, where he'll likely continue to develop as a starter. He could be back with the big club soon if he continues to dominate in the minors. Bryan Mitchell was recalled from Triple-A in a corresponding roster move.
The young right-hander has absolutely dominated at Double-A Trenton this season, posting a 1.13 ERA and 0.82 WHIP over nine starts, and was recently promoted to Triple-A Scranton/Wilkes-Barre. He'll get another shot in the big leagues after making his major-league debut in a relief appearance for the Yankees earlier this season -- where he allowed two earned runs over two innings in a loss to the Angels. Look for Herrera to be used in low leverage situations out of the bullpen as he acclimates to professional hitters.
Herrera was optioned to Double-A Trenton on Thursday.
He was recalled Wednesday to add some bullpen depth during the Yankees west coast swing, but a tough outing against the Angels earned him a trip back to Trenton. Herrera allowed a home run and two earned runs over 2.0 innings against the Halos while fanning two batters. He'll likely rejoin the rotation down at Trenton upon his return.
Herrera was recalled from Double-A Trenton on Wednesday.
Herrera was dominating Double-A before being promoted to the Yankees, as the 22-year-old worked a 1.07 ERA and 0.76 WHIP to a 7-0 record through 50.1 innings (eight starts). He's worked almost exclusively as a starter in the minors, so it's unclear how the big club intend to use him upon his arrival. He could possibly earn a spot start for the injured CC Sabathia or even be used out of the bullpen after Yankees relievers logged seven innings in Tuesday's extra-innings loss.
Herrera (shoulder) fired 5.1 scoreless innings in his season debut with Double-A Trenton on Sunday.
The 22-year-old was sidelined since spring training due to a bout of shoulder inflammation, but Sunday's outing seems to indicate that there aren't any lingering effects of that ailment. Herrera should continue to log starts with Double-A Trenton for much of the season, although more starts like this could get him a promotion to Triple-A somewhat soon.
