Winners of 16 of their last 20 games, the San Francisco Giants now find themselves with a .500 record and just .25 games back in the NL wild-card race.
Tonight they welcome the NL Central-leading Chicago Cubs to town.
The Cubs are hot as well, with a 7-3 record in their last 10 games and a two-game lead in the division standings.
This series could decide if the San Francisco Giants are contenders or pretenders.
The Chicago media is already speculating that if the Cubs can knock the Giants out of contention, they might be able to poach Will Smith or Tony Watson to shore up the need for a quality left-handed reliever in the bullpen.
