With Heath Bell having pitched three straight days, David Hernandez got the call in the ninth on Friday and protected a one-run lead against the Phillies. It was Hernandez's first save of the year. After a rough April, he's turned in four scoreless innings over the last week. The Diamondbacks would prefer Bell hold on to the closer's gig, but Hernandez is ready and waiting should Bell falter.

Called upon with J.J. Putz unavailable, David Hernandez blew a save against the Giants Wednesday, allowing a game-tying homer to Brandon Crawford in the ninth inning. Hernandez had to pitch out of a jam even after allowing the one-out dinger, as he gave up a two-out single and a walk before getting Marco Scutaro to end the threat. Both Hernandez and Putz have struggled of late, but it will surely be Putz that gets the next save chance.

The extension covers two of Hernandez's arbitration years, as he isn't eligible for free agency until after the 2015 season. The 27-year-old has been dynamite as a setup man for J.J. Putz since coming over via trade from Baltimore, posting a 3.23 ERA and 1.13 WHIP over 107 appearances. Whenever Putz's time runs out in the desert, Hernandez will likely take over as closer, which could make this deal a bargain.

David Hernandez pitched 1 1/3 scoreless innings and was credited with a save Friday against the Cubs. Hernandez entered a 6-1 game in the eighth, but since the tying run was on deck, it was a save situation. He got out of the jam and then pitched a perfect ninth for his second save of the season.
