Cubs Host Lowly Pirates Before Pivotal Brewers Series

The Chicago Cubs open an eight-game homestand on Friday, starting with a three-game series against the struggling Pittsburgh Pirates before hosting the Milwaukee Brewers in a crucial NL Central showdown.

Chicago returns home after a 2-4 road trip that ended with a 2-1 loss to the Toronto Blue Jays on Thursday. That defeat came when Vladimir Guerrero Jr. launched a two-run homer in the seventh inning to flip the score.

Colin ReaCubs9-54.091.216.0 IP, 1 ER vs. Cardinals
Braxton AshcraftPirates3-23.191.133.1 IP, 1 ER vs. Reds

Rea, the veteran right-hander, has found recent success against Pittsburgh. He allowed just two runs across 12 innings in two earlier starts this season, earning the win in an 8-3 Cubs victory on May 1 and taking a no-decision in a 3-2, 10-inning win on June 12.

The Cubs’ offense has been the main concern, scoring only seven runs across their last nine losses. Michael Busch provided a solo homer Thursday, but Chicago’s inability to sustain rallies remains an issue.

“We had a bunch of warning-track balls, but just couldn’t get an inning going, really at all,” manager Craig Counsell said.

The Pirates have dropped five straight, including a three-game sweep in Milwaukee where they were outscored 33-6. Wednesday’s 12-5 loss saw Bryan Reynolds break out for two homers and all five RBIs.

“We continue to battle, continue to have good at-bats,” interim manager Don Kelly said. “We need to carry that over to Chicago.”

Ashcraft, making his third start of the season, has already thrown two perfect innings at Wrigley Field this year in a relief appearance on June 14.

Chicago leads the season series 5-2 and will see the Pirates just once more this year after this weekend’s set.
