Outrighted: Bass, Mattheus, Walters, Morel

Several players were outrighted off of 40-man rosters today to clear space for players who needed to be protected from the Rule 5 draft:

• The Astros outrighted righty Anthony Bass, the club announced.  Bass, 27, has seen his ERA rise over each of the last four years, and he suffered in 2014 from a sudden inability to miss bats.
• Right-handed reliever Ryan Mattheus was outrighted by the Nationals, also per the club. Mattheus has elected free agency. Though he has been effective in long stretches at times in D.C., Mattheus never regained his place in the bullpen after breaking his hand last May. The 31-year-old, out-of-options righty should certainly find a club willing to give him a chance to earn a job out of camp.
• The Mets announced that Jeff Walters has been removed from the 40-man. A 27-year-old right-hander, Walters has yet to see MLB action. He struggled mightily in 2014, his first attempt at Triple-A, and ultimately was diagnosed with a torn UCL that required Tommy John surgery.
• The Pirates announced that infielder Brent Morel has been outrighted. Morel has seen relatively scant MLB time since a run with the White Sox in 2011. Last year, at Triple-A, he slashed .271/.335/.375 over 376 plate appearances.
