Diaz struck out four while allowing a hit and two walks over two scoreless innings Sunday to pick up his 20th save of the season in a 2-1 win over the Phillies.
Hanging onto a slim lead over Atlanta for the final wild-card spot, manager Carlos Mendoza did not hesitate to put Diaz in for another save opportunity just one day after throwing 17 pitches to get four outs. Diaz left Bryce Harper stranded on third in the eighth and then worked around a pair of walks in the ninth to shut the door on the Phillies. Diaz has given up just one run while owning a 21:3 K:BB in 11.1 innings during September and also reached 20 saves in a season for the sixth time in his career. He owns a 3.35 ERA, 1.00 WHIP and 79:18 K:BB in 51 innings on the year.
