MILWAUKEE (AP) _ Sean Halton hit his first career grand slam, Tyler Thornburg allowed just two singles over six innings, and the Milwaukee Brewers beat the Chicago Cubs 7-0 on Wednesday night.
Thornburg (3-1) struck out four and walked two as he reached six innings for the sixth straight start since being recalled from Triple A Nashville on June 29. He has allowed five earned runs in 36 innings as a starter and has also made 11 relief appearances for the Brewers this season. At Nashville, he was 0-9 with a 5.79 ERA in 15 starts.
Jimmy Nelson pitched two innings and Michael Blazek got the last three outs to preserve the four-hit shutout.
Halton's homer capped a five-run first inning off Chris Rusin (2-5).
Brewers shortstop Jean Segura left Wednesday night's game after the first inning with what the team announced as a strained right hamstring.
Segura, hitting .296, walked in the first inning, advanced on a single by Jonathan Lucroy and then scored from second on a single by Aramis Ramirez. Segura did not appear to slow down while running the bases.
He is listed as day to day.
The Brewers go for the four-game sweep of the Cubs Thursday afternoon at Miller Park. Coverage in Madison can be heard on 1310 WIBA starting at 12:35pm, with the first pitch to follow at 1:10pm.
