Pirates at Diamondbacks picks and predictions

Prediction

Pirates 5, Diamondbacks 4

Money line

Bumgarner’s surface stats at home are strong but the underlying numbers, including a 4.67 xFIP at Chase Field, don’t support his success. He has allowed 4 ER in each of his last 2 starts with just 2 K across 11 2/3 IP.

Bumgarner is tough to back at this price, and even a subpar Pittsburgh offense should get to him. Take the PIRATES (+133).

Run line/Against the spread

Though Keller’s skills don’t quite support the sub-2.00 ERA he has posted over his last 5 starts, he has been pitching well and has really cut down on the walks. Look for the PIRATES +1.5 (-155) to keep this one close even if they fall short of the outright win.

Over/Under

The total has gone over in 6 of Arizona’s last 8 games vs. a right-handed starter and they have averaged 4.8 runs per game since the All-Star break.

The total has gone over in just 2 of Pittsburgh’s last 8 contests against a lefty but the bats should get going against Bumgarner. Go with OVER 8.5 (+100) or adjust the line and play ALTERNATE TOTAL OVER 7.5 (-140).
