The San Francisco Giants will be looking to deny the Colorado Rockies a split in this four-game series at AT&T Park on Sunday afternoon. The Giants pulled off an 13th inning win yesterday, but several factors would suggest that we will see more action over the plate today.

Here are my keys to the game:

1. Pitching - The Giants hand the ball to Jeff Samardzija (4-1, 3.32) who is coming off his best start in a Giants uniform when he tossed eight innings of one-run ball at Cincinnati on Tuesday. The Shark was not quite as successful his last outing in San Francisco when he conceded five runs on five hits in 5 2/3 innings on April 27. Samardzija has made two day starts in 2016, giving up a total of eight runs in 11 innings. The Rockies counter with Eddie Butler (0-1, 6.75 ERA) as the 25 year old is set to make his third start of the year. Butler surrendered five runs on four hits with a pair of homers in a 6-3 loss at San Diego his last start.

2. Taxed Bullpens - The Rockies used six relievers in yesterday's contest while the Giants asked five pitchers to come out of the bullpen in yesterday's marathon game. Hardly ideal for today as both teams bullpens rank in the bottom third of the majors.

3. X-Factor - The over is 13-3 in the Giants last 16 overall and eight of their past 10 home at AT&T Park have gone over the total.

Selection: This is a play on COL@SF to go OVER the total (8*)
