Reds purchased the contract of RHP Ryan Dennick from Triple-A Louisville.
Dennick, 27, had a 2.36 ERA and 39/18 K/BB ratio over 49 2/3 innings this season in Triple-A. He'll pitch in middle relief in first taste of the majors.
Reds purchased the contract of OF Jason Bourgeois from Triple-A Louisville.
Bourgeois owns a .259/.305/.326 batting line in the majors. He'll serve as an extra outfielder this month.
Jim Hayes of Fox Sports Midwest hears that the Cardinals are leaning toward starting Marco Gonzales against the Brewers on Thursday.
Gonzales would take the spot of Justin Masterson in the starting rotation. It makes sense, as the southpaw tossed six innings of one-run ball in a spot start against the Cubs on Saturday. Still, he's a risky option in mixed fantasy leagues.
Phillies activated RHP Mike Adams from the 60-day disabled list.
Adams has been out since early June with right rotator cuff inflammation, but he made it through three rehab appearance without incident. He's finishing up a two-year, $12 million contract.
Giants purchased the contract of RHP Chris Heston from Triple-A Fresno.
Heston, 26, compiled a 3.38 ERA and 125/51 K/BB ratio in 173 innings across 28 starts this season. He has pitched almost exclusively as a starter in the minors, but the Giants will likely use him in long relief.
