SARASOTA, Fla. -- The Baltimore Orioles have optioned left-handers Bruce Zimmermann and Nick Vespi and reassigned infielder Lewin Díaz, left-hander Darwinzon Hernandez and catcher Mark Kolozsvary to minor league camp.
The Orioles announced the moves Monday.
Baltimore's spring training roster now has 46 players.
Zimmermann made 13 starts last season. He went 2-5 with a 5.99 ERA.
The competition for rotation spots with the Orioles has been a significant story during spring training, but after the team acquired Cole Irvin and Kyle Gibson in the offseason - and with top prospect Grayson Rodriguez in the mix as well - there were a lot of pitchers Zimmermann needed to beat out.
