Season series: Giants lead 6-5

The Giants enter play 2 games back for a Wild Card spot in the jumbled National League standings. There are 5 teams basically vying for 2 Wild Card spots with the Philadelphia Phillies 3 1/2 games clear of the rest of the pack for one of the other card spots.

San Francisco made things hard on itself by dropping 3 of 4 games against lowly Colorado on the road over the weekend, and it is just 6-10 in the past 16 games overall. The Over and Under has alternated in the past 7 games.

The Giants optioned prospect Kyle Harrison to Triple-A over the weekend. Tuesday was to be his turn in the rotation. Veteran RHP Alex Cobb will get the nod in his stead.

Arizona is one of those teams vying for a postseason spot, entering play a half-game clear of the Chicago Cubs and Cincinnati Reds, and a full game up on the Miami Marlins, while sitting 2 1/2 games ahead of the Giants. So, this is an ultra-important game.

The Diamondbacks picked up a key 3-game sweep of the Cubs over the weekend, scoring at least 6 runs in each of the victories. The Over is 5-1 in the past 6 games overall.
