The Padres have designated lefty Eury De La Rosa for assignment, the club announced. San Diego selected the contract of corner infielder Brett Wallace in a corresponding move, necessitating a 40-man spot.
De La Rosa, 25, has pitched exclusively at Triple-A this year, working to a 4.03 ERA with 6.9 K/9 against 5.6 BB/9 over 22 1/3 frames. That represents a career-worst K:BB ratio in his professional career.
The southpaw spent time in the Diamondbacks bullpen over the past two seasons, putting up a 4.21 ERA in 51 1/3 total frames. De La Rosa bounced from the D’Backs to the Athletics and then to the Dodgers in recent months before reaching San Diego on a waiver claim.
The 28-year-old Wallace, a former top prospect, will make his first big league appearance for a team other than the Astros. He hasn’t seen the show since 2013, but owns a career .242/.313/.391 slash in just over 1,000 career plate appearances in the majors. Wallace has (as usual) hit Triple-A pitching well this year, slashing .305/.380/.460 while carrying a 21.1% strikeout rate.
