Here are today's minor moves and outright assignments from around the league…
- Troy Renck of the Denver Post reports that the Rockies have agreed to a minor league deal with right-hander Richard Castillo. A former Cardinals prospect, the 24-year-old Castillo split 2013 between St. Louis' Double-A and Triple-A affiliates, posting a combined 4.08 ERA with 5.3 K/9 and 3.2 BB/9 in 147 2/3 innings. Baseball America twice ranked him among the Cardinals' Top 30 prospects, but he has not cracked that list for the past four years.
- The Orioles announced that they've signed right-handed knuckleballers Eddie Gamboa and Zach Clark to minor league deals. Gamboa received an invitation to Major League Spring Training. The 29-year-old posted a 4.43 ERA with 7.2 K/9 and 3.7 BB/9 in 142 1/3 innings between Baltimore's Double-A and Triple-A affiliates in 2013. Clark, 30, made his big league debut in 2013, allowing three runs in 1 2/3 innings. He had a 7.84 ERA in 111 1/3 innings across four minor league levels last season.
- The Brewers released right-hander Nick Bucci, according to Tom Haudricourt of the Milwaukee Journal-Sentinel (on Twitter). Formerly one of Milwaukee's top prospects, Bucci dealt with a shoulder injury this season and pitched just two-thirds of an inning this season. The injury-plagued 23-year-old has pitched just 43 1/3 innings over the past two seasons.
- The Padres have outrighted right-hander Adys Portillo to Double-A San Antonio, according to the team's transactions page. The 22-year-old was designated for assignment over the weekend to clear a 40-man roster spot for Joaquin Benoit. Portillo received a $2MM signing bonus in 2008 but has yet to provide the Friars with much of a return on that investment.
