Cubs purchased the contract of RHP Joel Peralta from Triple-A Iowa.
Gerardo Concepcion was optioned to Triple-A in the corresponding roster move. Before his call-up, Peralta posted a 4.50 ERA with two saves over five outings for Iowa. The 40-year-old joined the Cubs on a minor league deal earlier this month after being released by Seattle.
Matt Cain (hamstring) is slated to begin a rehab assignment on Friday.
Cain completed a 36-pitch bullpen session on Sunday and will throw another on Tuesday. He's been battling hamstring issues for the past month. Cain is only 1-5 this year with a mediocre 5.34 ERA over 11 starts. He hasn't been on the fantasy radar in quite some time.
The Mets have no plans to trade top SS prospect Amed Rosario.
The Mets could be open to making a trade this summer—Brewers catcher Jonathan Lucroy is one player they've had their eye on—but Rosario isn't going anywhere. The 20-year-old has impressed this year by hitting .317 with 42 RBI and 14 steals over 70 games for High-A St. Lucie and Double-A Binghamton. He's listed at No. 70 in MLB.com's prospect rankings.
George A. King III of the New York Post believes Alex Rodriguez might only start against lefties going forward.
He got the day off Sunday against Twins right-hander Tyler Duffey with Carlos Beltran filling in at DH. A-Rod has been useless against right-handers this year (.200 AVG in 115 at-bats) but has hit a respectable .275 versus lefties. "He has struggled against some right-handers," manager Joe Girardi admitted. "We talked about giving Carlos some DH days in this long stretch and I would be more inclined to do it against right-handers than left-handers." Rodriguez was a pleasant surprise last season in his return from a yearlong PED suspension but he hasn't shown us much in 2016.
Seung Hwan Oh warmed up in the eighth inning Sunday against the Mariners but wasn't needed after the Cardinals scored two runs in the ninth.
The implication is that Oh would have been manager Mike Matheny's first choice had their been a save situation. The Cardinals have gone to a closer by committee in the wake of Trevor Rosenthal's recent struggles. Oh has enjoyed a brilliant rookie campaign, contributing 14 holds and a stellar 1.66 ERA over 37 appearances. Jonathan Broxton and Kevin Siegrist could also get looks in the ninth inning but Oh needs to be owned in all formats.
Gregory Polanco (leg) is not in the Pirates' lineup Monday against the Dodgers.
Polanco hasn't been in the lineup the past three days while battling left leg discomfort, though he did strike out in a pinch-hitting appearance Sunday night. Utility man Sean Rodriguez is getting the nod in right field. He'll bat seventh against Dodgers lefty Scott Kazmir. Polanco remains day-to-day.
The Mariners are "leaning toward" having Taijuan Walker (foot) start Thursday against the Orioles.
He was skipped last time through the rotation after being diagnosed with tendinitis in the arch of his right foot. Walker threw a bullpen session on Sunday and reported no issues. The right-hander holds a respectable 3.45 ERA in 14 starts this year. Unfortunately he's been plagued by a severe lack of run support and only has three victories.
Aaron Blair is due for an extended stay in the minor leagues.
Atlanta shipped Blair to the minors last month so he could work on his mechanics but injuries forced him back into the starting rotation after only one outing. After another tough stint in the major leagues, the Braves intend to let Blair work through his issues in Triple-A. "He’s a big part of what we’ve got going forward," said interim manager Brian Snitker. "We're trying to help and do the right thing for [him] right now, what’s best for Aaron Blair." The 24-year-old has struggled to a 7.99 ERA over 11 winless outings for the Braves this season.
