Sosa hit his 549th career homer Saturday in the Cubs’ 7-5 win over the Padres, moving past Mike Schmidt into sole possession of ninth place on the all-time list.
He had tied Schmidt with his 548th in Friday’s 6-1 win in the series opener. Next on the list is Reggie Jackson at 563.
Sosa hit a two-run shot off Adam Eaton in the fifth inning Saturday. It was his 10th of the season, and it was estimated at 434 feet, the longest homer in 21 games at Petco Park.
Padres starter David Wells will now try to slow down Sosa and the Cubs. The 41-year-old left-hander said he did not feel fresh in his most recent outing.
Wells, who has lasted at least six innings in all but one of his seven starts, gave up four runs and five hits through seven innings Tuesday in a 6-3 loss to the Cincinnati Reds.
“I felt sluggish,” Wells said. “I should have thrown yesterday, played catch or something just to kind of get my arm to feel better than it did today.”
The Padres will be trying to avoid getting swept for the first time this season.
