The Cubs have designated righty Gonzalez Germen for assignment and moved infielder Tommy La Stella (oblique) to the 60-day disabled list, MLB.com’s Carrie Muskat tweets. The moves clear space on the Cubs’ roster for two new additions, pitcher Clayton Richard (who will start for the Cubs today) and catcher Taylor Teagarden (who will fill in as a backup while David Ross recovers from a concussion).

The 27-year-old Germen pitched six innings of relief for the Cubs this season, allowing five runs while striking out eight and walking five. He’s also pitched 33 1/3 relief innings for Triple-A Iowa this season, posting a 3.78 ERA, 7.3 K/9 and 4.6 BB/9.

Gonzalez’s DFA marks the fourth time since December that he’s been designated for assignment. Following a strong season in the Mets farm system in 2014, he went from the Mets to the Yankees to the Rangers and then to the Cubs within a period of six weeks last offseason.
