Diaz notched his third save of the season in Thursday's 2-1 win over the Tigers, giving up a hit and recording two strikeouts.
The young closer fired nine of 11 pitches for strikes while disposing of Justin Upton, Alex Avila and James McCann. Diaz worked around a pinch-hit single by Andrew Romine to post his third straight scoreless one-inning appearance. The 23-year-old has now racked up nine strikeouts over 8.2 innings and has lowered his ERA from 6.35 to 4.15 over his last three trips to the mound.
