Bradley Blalock: Everything you need to know

The Marlins optioned Blalock to Triple-A Jacksonville on Monday, Christina De Nicola of MLB.com reports. Blalock was acquired from the Rockies in January after he was DFA'd by Colorado. The 25-year-old right-hander has appeared in 21 career regular-season games at the MLB level, making 18 starts, but has turned in an 8.16 ERA, 1.83 WHIP and 47:43 K:BB across 89.1 innings.

The Marlins acquired Blalock from the Rockies on Tuesday in exchange for Jake Brooks, Jeff Passan of ESPN.com reports. Blalock had been designated for assignment last week and is now headed to a new organization. The right-hander holds an abysmal 8.16 ERA and 47:43 K:BB over 89.1 innings in parts of two seasons at the major-league level, but the Marlins appear optimistic they can get more out of Blalock. The 25-year-old will give Miami some rotation depth following its trades of Edward Cabrera and Ryan Weathers.

The Rockies designated Blalock for assignment Thursday, Patrick Saunders of The Denver Post reports. The club needed to free up a spot on its 40-man roster for the addition of Michael Lorenzen, whose signing was officially announced Thursday. Blalock has been dreadful in the big leagues to this point, posting an 8.16 ERA and 47:43 K:BB over 89.1 innings in parts of two seasons. Perhaps another team believes it can coax more out of him outside Colorado, but it's likely he will clear waivers.
