Minor Moves: Alderson, DeVoss, Stewart, Henderson

Here are some recent minor league transactions from around baseball, with the newest moves at the top of the post…

• Two minor league signings were posted today by the Athletics, as the club landed righty Tim Alderson and outfielder Zeke DeVoss, according to the MLB.com transactions page. Alderson, a 25-year-old former first-rounder and top-100 prospect, has seen his career stall. He has struggled to a 6.12 ERA in 50 relief innings this year for the Orioles’ top affiliate. DeVoss, just 24 years old, was a third-round pick in 2011 but failed to progress this year for the Cubs.
• The Angels have outrighted infielder Ian Stewart to Triple-A, according to the PCL transactions page. He was designated for assignment two days ago. It is not yet clear whether Stewart has accepted the assignment. (He has the right to choose free agency because he has previously been outrighted.)
• The Brewers shifted right-hander Jim Henderson from the 15-day disabled list to the 60-day, the club announced via Twitter.  Henderson’s 40-man roster spot will be filled by righty Jeremy Jeffress, who contract was selected by the Brewers in a corresponding move.
• The Giants signed righty Mitchell Boggs, Baseball America’s Matt Eddy reports.  Boggs had a 9.50 ERA, 18 strikeouts and 17 walks over 36 relief innings for the White Sox Triple-A affiliate this season before being released earlier this month.  A reliable contributor for the Cardinals’ bullpen from 2010-12, Boggs developed major control issues last season, and the Giants are now his fourth organization in a little over a year’s time.
• The Royals released right-hander Ramon Troncoso, the club announced last week.  Troncoso signed a minor league contract with K.C. in March and produced a 4.30 ERA, 6.8 K/9 and an even 3.0 K/BB rate over 44 IP with Triple-A Omaha.  Troncoso pitched 30 relief innings for the White Sox in 2013, his first taste of big league action since 2011.
• The Phillies released utilityman Rusty Ryal, according to Matt Provence, media relations director for Triple-A LeHigh Valley (Twitter link).  Ryal, 31, appeared in 134 games with the Diamondbacks from 2009-10 and hasn’t been back to the majors since, playing in the minors for five different organizations since.  He signed a minor league deal with the Phillies in June.
