The Cubs have promoted righty Erich Uelmen from Triple-A Iowa, giving them a fresh arm in the bullpen as they finish out the first half. A fourth-round pick out of Cal Poly San Luis Obispo in 2017, Uelmen has a 2.79 ERA with 52 strikeouts and 23 walks in 42 innings for Iowa this season. He has given up two homers in that time after allowing 16 dingers in 90.1 innings between Tennessee and Iowa last season.
In order to make room on the roster for Uelmen, lefty Daniel Norris has been designated for assignment. The 29-year-old made a costly error in Saturday’s nightcap that might have sealed his fate. When you’re putting up a 6.90 ERA born of a dangerous combination of too many walks and homers, there’s very little slack to be cut.
Anderson Espinoza, who was the 27th man for the doubledheader, has been optioned back to Triple-A Iowa.
