Diaz picked up the save Thursday against the Phillies and struck out the only batter he faced.
Diaz came in to get the last out, as he was assigned to face Phillies superstar Trea Turner with runners on first and second. The right-hander retired him on five pitches to secure his second save in as many chances. Diaz has been unscored upon in four of five outings but has an inflated 6.23 ERA since he allowed three earned runs in his other appearance.
