Minor MLB Transactions: 8/16/17

Here are some of the latest minor moves from around the game, courtesy of Baseball America’s Matt Eddy except where otherwise noted:

• The Mariners outrighted right-hander Christian Bergman to Triple-A after he cleared waivers, per a club announcement. Bergman, 29, had the right to opt for free agency now or at the end of the season; given that he’s now listed on Tacoma’s roster, it seems he’ll wait and consider the latter option when the time comes. Bergman, 29, has thrown 51 1/3 innings on the year for Seattle, working to a 4.91 ERA with 5.9 K/9 and 2.5 BB/9.
• Outfielder Daniel Robertson will return to the Indians on a minors deal after being designated for assignment and then released, the club announced. The 31-year-old has appeared in each of the past four MLB campaigns — each time with a different team.  This year, he took 88 plate appearances for Cleveland, slashing .225/.287/.338. While it’s not clear whether Robertson will factor at the major league level again this year, the fleet-footed, high-contact 31-year-old could conceivably make for a useful bench piece once rosters expand in September.
• The Diamondbacks have added right-handers Andury Acevedo and Louis Coleman on minors deals. Acevedo, who’ll soon turn 27, was intriguing enough to land a 40-man spot with the Cubs a few years back, but has yet to show any consistency on the mound in the upper minors. As for Coleman, who threw 48 innings of 4.69 ERA ball last year for the Dodgers, he’ll return to Arizona after briefly testing the open market. He has worked to a 2.05 ERA with 10.6 K/9 and 4.1 BB/9 over 57 innings this year in stints with the D-Backs’ and Reds’ top affiliates.
• Heading to the Reds on a minors deal is slugging outfielder Adam Walker. He has bounced around via waiver claims and minor-league deals of late, seeing time in three organizations thus far in 2017. All told, he has compiled a tepid .185/.220/.410 batting line — with a dozen home runs but also 88 strikeouts against just ten walks — in his 241 plate appearances in the upper minors.
• The White Sox released infielder Grant Green, who had previously seen brief action in the majors this year with the Nationals. On the season, Green owns an overall .232/.306/.300 slash over 245 plate appearances at the Triple-A level with those two organizations. The 29-year-old was once considered a notable possible contributor with the Athletics and Angels, but has managed only a .248/.283/.336 batting line in his 353 trips to the plate in the majors.
• Six-year MLB veteran Collin Cowgill has been released by the Padres. Cowgill, 31, joined the organization on a minors deal over the winter, but never earned a crack at a return to the majors. He carries a .235/.297/.390 slash through 220 plate appearances
• Finally, the Rangers have released lefty Bobby LaFromboise and righty Jaye Chapman. The former has made 27 MLB appearances and shown some intriguing numbers at times, but struggled last year at Triple-A with the Phillies and was sidelined for much of the current season. The 30-year-old Chapman, meanwhile, is looking to work back toward the majors for the first time since his lone stint back in 2012. But he was hit hard in his 36 2/3 innings at Triple-A Round Rock, with a 6.63 ERA and 6.9 K/9 against 5.2 BB/9.
