After a rough start, Edwin Jackson retired 17 of the final 18 batters he faced, but the Cubs were held to five hits by rookie Mike Bolsinger and three relievers in a 5-2 loss to the Arizona Diamondbacks at Wrigley Field on Thursday afternoon.
Nate Schierholtz struck out for the first out then Starlin Castro walked to load the bases with Mike Olt at the plate. Olt struck out and birthday boy Welington Castillo lined out to former Cub Tony Campana in center to strand three runs.
Jackson (1-2, 5.02 ERA) gave up three earned runs on five hits, struck out four and walked two over seven innings.
Bolsinger (1-1, 5.27 ERA) gave up one unearned runs on four hits, struck out seven and walked two over 6 2/3 innings. Former Chicago White Sox closer Addison Reed earned the saved.
The Cubs (7-14) open a three-game series Friday night against the Milwaukee Brewers and Matt Garza at Miller Park.
