Cubs Bolster Bullpen by Reacquiring Reliever Tyson Miller from Mariners

Chicago trades minor league infielder Jake Slaughter to Seattle as bullpen injuries mount

Tyson Miller, originally drafted by the Cubs in 2016, returns with a 3.09 ERA this season.
The Cubs designated left-hander Richard Lovelady for assignment to make room for Miller.
Adbert Alzolay's forearm injury adds to the Cubs' bullpen woes, prompting the trade.
Miller has been effective with a 12-to-1 strikeout-to-walk ratio in 11.2 innings for Seattle.
Jake Slaughter, traded to the Mariners, has been performing well in Triple-A with a .297 average.
