Twins sent INF Doug Bernier outright to Triple-A Rochester.
Bernier was already in the minors and now he's off the 40-man roster. He had one hit in five at-bats in a brief stay in the majors earlier this season.
Blue Jays sent INF Steve Tolleson outright to Triple-A Buffalo.
He cleared waivers after being designated for assignment and will remain with the organization. Tolleson could get another shot with the big club at some point.
Pirates sent RHP Chris Volstad outright to Triple-A Indianapolis.
Volstad had been designated for assignment after a two-inning scoreless appearance with the big club. He returns to a 3.43 ERA at Indy.
Astros recalled RHP Dan Straily from Triple-A Fresno.
Straily will take the ball on Friday against the Red Sox. He owns an uninspiring 4.06 ERA and 1.38 WHIP for Fresno this season, although it's come along with a nice 70/14 K/BB ratio over 77 2/3 innings. He could get a couple starts with the big club until Scott Feldman (knee) is ready to return.
CBS Sports' Jon Heyman reports that Dioner Navarro "renewed his interest in a trade this week."
Navarro requested a trade over the winter after the Blue Jays signed Russell Martin and he apparently still desires to be somewhere where he could catch more. He's been the Jays' backup catcher and occasional designated hitter but would probably represent an upgrade as a starting catcher for a handful of clubs.
CBS Sports' Jon Heyman reports that Jeff Samardzija "is on the list" of the Blue Jays.
Samardzija has already been dealt twice over the last year and the impending free agent is likely to be on the move again with the White Sox out of contention. The right-hander has put up a disappointing 4.56 ERA this season, but his stuff looks to be intact and he would be a welcome upgrade to the Blue Jays' rotation.
CBS Sports' Jon Heyman reports that the "word for now seems to be that it's unlikely" Cole Hamels would approve a trade to the Astros.
Heyman says that Houston "would love" the southpaw, but "there still is no reason to believe its feeling is reciprocated by Hamels." The left-hander could always change his mind, of course, and it also might wind up being a moot point if another teams offers a better trade package. The Astros certainly appear to be in the market for a big arm this month.
CBS Sports' Jon Heyman reports that the Astros and Dodgers had two scouts apiece at a recent Johnny Cueto start versus the Mets.
Heyman notes that "some of the scouts might have been there doing regular/advance coverage." However, it's no secret that both the Astros and Dodgers are among the clubs interested in the veteran right-hander. The Blue Jays and Yankees are two other teams known to have interest. Cueto has appeared to put his elbow issue behind him and should fetch a nice return for the Reds later this month.
