Randal Grichuk will make his first career start tonight for the Cardinals, MLB.com’s Jenifer Langosch tweets. Grichuk will start in center field, a position usually occupied by Peter Bourjos. The Cardinals acquired both players this offseason, dealing David Freese and Fernando Salas to the Angels in a bid to upgrade their defense. The Cardinals have gotten little from Bourjos and from right fielder Allen Craig so far this season, while Grichuk and the Cardinals’ other Triple-A outfielders have excelled, so the Cardinals promoted Grichuk on Sunday. Here are more notes from around the NL Central.
- Brewers prospect Johnny Hellweg had Tommy John surgery today, the Journal Sentinel’s Tom Haudricourt tweets. Baseball America’s Prospect Handbook 2014 ranked Hellweg the No. 4 prospect in a weak Brewers system. The 6-foot-9 righty walked 6.8 batters per nine in 126 Triple-A innings in 2013, and struggled badly with his control in 31 big-league innings. When healthy, however, he has an outstanding fastball, and gets plenty of outs on the ground.
- Reds closer Aroldis Chapman could make a rehab appearance in Dayton on Thursday, C. Trent Rosecrans of the Cincinnati Enquirer tweets. Chapman has been out since being hit in the face with a line drive in an ugly injury suffered in spring training.
