Rockies add INF DJ LeMahieu and OF Andrew Brown to big-league roster, place Jonathan Herrera and Chris Nelson on disabled list.— Tracy Ringolsby (@ROOTSPORTS_TR) July 17, 2012
To replace Nelson and Herrera on their roster, the Rockies added infielder D.J. LeMahieu and utilityman Andrew Brown.
Nelson has been suffering from an irregular heartbeat. The 26-year-old had his heart shocked back into rhythm Tuesday afternoon and is recovering in a local hospital, according to Troy E. Renck of The Denver Post. Before hitting the DL, Nelson had posted an OPS of .735 for the Rockies this season.
Herrera sustained a wrist injury recently, an infection caused by a wristwatch, which landed him on the 15-day DL. On the season, the 27-year-old maintained an OPS of .678.
LeMahieu has played in 19 games for the Rockies this season, collecting eight hits over his 39 at-bats. He owns a career major league OPS of .525 over 99 at-bats.
