Athletics optioned INF Max Muncy to Triple-A Nashville.
Muncy gets the boot to clear a roster spot for Danny Valencia, who was claimed off waivers from the Blue Jays on Monday. Muncy, 24, has batted just .207/.275/.378 in 91 plate appearances this season for Toronto.
Tigers owner Mike Ilitch has fired general manager Dave Dombrowski.
Al Avila is taking over as the club's new GM and executive vice president of baseball operations. "I've decided to release Dave from his contract in order to afford him the time to pursue other career opportunities," Ilitch wrote in a statement to the media. "I feel this is the right time for the Tigers to move forward under new leadership." Detroit is in the midst of a highly dissapointing 2015 season and became sudden sellers at last week's trade deadline, but the firing is still a shock. Dombrowski had an incredible run of regular-season success with the Tigers, winning four straight AL Central titles between 2011-2014.
Mason Williams will have right shoulder surgery on Friday.
Williams jammed his shoulder in June and continues to have discomfort. The surgery will end his season. It's too bad, as the 23-year-old was having a nice bounceback year prior to the injury.
Daniel Murphy is not in Tuesday's lineup against the Marlins.
Murphy will take a seat against left-hander Brad Hand. Wilmer Flores will start at second base while Juan Uribe plays third.
Yoenis Cespedes will bat second Tuesday against the Marlins.
Cespedes batted third in his first three games with the Mets, but Terry Collins has moved him up a spot in the order against left-hander Brad Hand. Juan Uribe is batting third while Lucas Duda will hit cleanup and Travis d'Arnaud will bat fifth.
Yankees general manager Brian Cashman has ruled out Michael Pineda (forearm) returning in August.
It's not a big surprise. Pineda was shut down last week with a right flexor forearm muscle strain and is still a few days away from throwing. The Yankees will likely have him make a couple of minor league rehab starts, so a return in September is more realistic.
Yankees general manager Brian Cashman said Tuesday that Dustin Ackley (back) is expected to miss 20-30 days.
Ackley, who was acquired from the Mariners last week, was placed on the disabled list Tuesday with a right lumbar strain. He was healthy at the time of the trade, so the Yankees have no dispute with the Mariners. Still, it's a tough break. Cashman says that surgery could be an issue if he doesn't show improvement.
Stephen Piscotty will bat second Tuesday against the Reds.
This makes back-to-back starts for Piscotty out of the No. 2 spot. The 24-year-old has batted .400/.450/.514 through his first 40 plate appearances in the majors and is gaining momentum in mixed fantasy leagues.
