The right-hander has won both outings since a brief stint on the disabled list due to shoulder inflammation, pitching seven innings each time.

Gamel began the embarrassing sequence when he overcharged the ball onGary Sanchez's RBI single, allowing the All-Star catcher to reach second.
After a walk toAaron Judge, the Yankees loaded the bases when Segura was charged with his first error after failing to catchDidi Gregorius' popup as three players converged in shallow left-center. Seager followed that with his own error, fumblingChase Headley's grounder as New York took a 2-1 lead.
Jacoby Ellsburyhit a two-run double, and Segura made two more errors on the play. First, when he mishandled Gamel's throw, allowing Headley to score, and then when his errant throw to the plate skipped past catcherMike Zunino, which sent Ellsbury to third.
Castro finished 4 for 4 andRonald Torreyesadded three of New York's 15 hits. Pinch-hitterGreg Birdhad a two-run single in the seventh.
Albers was charged with eight runs -- three earned -- and 11 hits in five-plus innings.
