The Mets placed Nunez on the 15-day injured list Thursday with a right elbow sprain.

Nunez has done a nice job with the Mets since being recalled from Triple-A in late June, giving up two runs over six innings while striking out eight batters and logging two holds. However, he won't get another chance to pitch until after the All-Star break thanks to an elbow sprain that appeared following his last outing Wednesday. Paul Blackburn (shoulder) will move to the IL with Nunez, creating space for Justin Hagenman and Rico Garcia to join New York.

The Rockies recalled Agnos from Triple-A Albuquerque on Thursday.

Agnos served as the Rockies' closer for a stretch earlier this season but was sent down after being scored upon in four straight outings. He appeared to get back on track at Albuquerque, permitting one run with a 4:1 K:BB in four frames. Agnos could re-enter the late-inning mix for the Rockies but is unlikely to be a frontrunner for saves right away.

The Rockies optioned Chivilli to Triple-A Albuquerque on Thursday.

Chivilli yielded two runs while recording just two outs in Wednesday's loss to the Astros in what was his second appearance in as many days. Zach Agnos was called up from Triple-A to replace Chivilli on the 26-man active roster and will give the Rockies a fresh bullpen arm.

The Mets optioned Warren to Triple-A Syracuse on Thursday.

Warren will return to Triple-A after he was up with the Mets for just one day as the 27th man for Wednesday's doubleheader with the Brewers. The right-handed reliever ended up going unused in both games of the twin bill.

The Brewers optioned Yoho to Triple-A Nashville on Thursday.

Yoho will return to Nashville after he was called up Wednesday to serve as the Brewers' 27th man for their doubleheader with the Mets. The right-handed reliever was used in the Brewers' 7-3 loss in the second game of the day, working 1.1 innings while striking out one and allowing one earned run on one hit and one walk.

The Reds optioned Zulueta to Triple-A Louisville on Thursday.

After the second game of the Reds' series in Boston was suspended Tuesday due to rain, both teams were allotted a 27th man Wednesday for the resumption of the suspended game in addition to the contest scheduled for that day. Zulueta was summoned from Louisville to serve as the Reds' 27th man but went unused in both contests.

Junk (2-1) took the loss Wednesday as the Marlins were downed 2-1 by the Twins, giving up two runs on six hits over six innings. He struck out seven without walking a batter.

The 29-year-old righty set a new season high in strikeouts en route to his first career quality start, but a Kyle Stowers solo shot in the second inning was all the offense Miami could muster for him. Junk has had a couple stumbles since joining the Marlins' staff in late May, but he's made a good case to stick in the rotation as either a traditional starter or bulk reliever, posting a 3.62 ERA, 1.13 WHIP and eye-popping 33:2 K:BB over 37.1 innings in eight appearances (three starts). He's scheduled to make his next trip to the mound on the road early next week in Cincinnati.

Ashcraft (groin) threw about 20 pitches in a live batting practice session Wednesday, Molly Burkhardt of MLB.com reports.

Ashcraft is closing in on a return following a couple of bullpen sessions over the weekend and then Wednesday's batting practice. The next step could be a brief rehab stint, or the Reds could opt to activate him, as the right-hander has completed the 15-day minimum on the IL.

Doval (4-2) blew a save but picked up the win Wednesday against Arizona, allowing two runs on two hits with three strikeouts over two innings.

Doval surrendered a game-tying two-run home run to Ketel Marte in the bottom of the ninth, but he returned for the 10th inning -- inheriting a one-run lead -- and retired the side to wind up with a win. Doval is in the midst of a rough patch, having allowed multiple runs in three of his last four appearances. The stretch has inflated his ERA from 1.59 to 3.03.

Miller (3-3) took the loss Wednesday against San Francisco, allowing an unearned run on one hit over one inning.

After Ketel Marte's two-run homer in the bottom of the ninth tied the ballgame, Miller took the mound for the top of the 10th and allowed an infield single to Heliot Ramos that advanced the automatic runner to third. Patrick Bailey plated the automatic runner with a sacrifice fly before Miller induced a double play. Arizona couldn't scrape a run across in the bottom half, resulting in a tough-luck loss for Miller. In his last six outings, the right-hander has allowed two runs (one earned) with nine strikeouts and no walks across 6.1 innings. He has a 2.04 ERA this season and should continue operating as Arizona's primary closer.
