Willson Contreras is not in Monday's lineup versus the Pirates.
Miguel Montero will start in his place and catch left-hander Brett Anderson. He's batting seventh against Chad Kuhl.
Mariners manager Scott Servais is mulling over using Edwin Diaz in high-leverage situations earlier in games in order to get him more regular work.
With the Mariners off to a disappointing start, Diaz has only made six appearances this season and just one since April 16. The hard-throwing 23-year-old hasn't been particularly sharp, which Servias believes is because of a lack of consistent work. "He needs to pitch," said Servais. "I don’t just want to stick him down there and wait because he’s the closer. He is so young. It may depend on where we are in the game. He hasn’t pitched much lately at all." It's a smart idea to use him outside of the constraints of the closer role if the situation warrants, though fantasy owners could miss on a save chance or two if he follows through with his idea.
The newly-acquired David Hernandez is expected to immediately join the Angels' bullpen, reports Chris Cotillo of SB Nation.
It makes sense given the extensive injuries with the Angels' relief corps. Hernandez, 31, had a 3.84 ERA with 9.9 K/9 in 70 relief appearances with the Phillies last season and began this year with a 1.12 ERA and 9/2 K/BB ratio over eight innings with the Braves' Triple-A affiliate. Bud Norris and Blake Parker appears to be at the top of the depth chart for saves, but Hernandez could be a dark horse option in this brittle bullpen.
Kirk Nieuwenhuis accepted an assignment to Triple-A Colorado Springs.
Nieuwenhuis surprisingly passed through waivers unclaimed after being designated for assignment on Friday. The Brewers have a crowded outfield situation in Triple-A, but Nieuwenhuis is useful depth to have around.
Aaron Nola (back) is only expected to miss 1-2 starts.
Nola felt some soreness in his lower back during his most recent start Thursday against the Mets and it lingered during a side session Sunday, so the Phillies don't want to take any chances. He could return as soon as next Monday. Ty Kelly is expected to take his place on the active roster, but Nick Pivetta will likely take his spot in the rotation on Wednesday.
Angels acquired RHP David Hernandez from the Braves for a player to be named later or cash considerations.
The Angels are missing Cam Bedrosian, Huston Street, Andrew Bailey, and Mike Morin to injury at the moment, so Hernandez will provide an experienced arm for the bullpen. The 31-year-old had a 1.12 ERA and 9/2 K/BB ratio over eight innings with the Braves' Triple-A affiliate. He could join the major league roster soon.
Jim Bowden of ESPN.com and MLB Network Radio on SiriusXM reports that the Nationals have been in touch with several teams about their closers.
Bowden writes that the Nationals believe Koda Glover can be their long-term answer at closer, but they aren't sure he's ready right now. Not surprisingly, Bowden mentions White Sox closer David Robertson and Rays closer Alex Colome among the possible trade options, but he adds that they haven't been able to meet either team's lofty asking prices. We expect to hear more about this situation as the season moves along.
Phillies placed RHP Aaron Nola on the 10-day disabled list, retroactive to April 21, with a lower back strain.
It's unclear how long Nola will be sidelined. Matt Gelb of the Philadelphia Inquirer writes that Nick Pivetta is likely to fill in Wednesday against the Marlins. Nola has posted a 4.50 ERA and 15/6 K/BB ratio in 16 innings through his first three starts this season.
