Holmes Gets the Nod to Begin Series
Clay Holmes is on the mound in this clash. Holmes came through with yet another gem in his previous outing, conceding one run in six innings against the Angels, and secured the win. The veteran has been the Mets' ace in the first month of the season. Holmes has yielded two or fewer runs in each outing and is sporting a robust 1.69 ERA and a 0.98 WHIP, accompanied by a 4-2 record in 42.2 innings pitched. He has yielded 31 strikeouts. Holmes squandered eight runs (five earned) in seven innings in his only meeting against the Diamondbacks.
The New York Mets are having a disappointing season, but there is plenty of time to get within reach of a wildcard spot. They are near the end of a nine-game road trip. The Mets won two of three against the Angels last weekend and two of three bouts against the Rockies this week, led by the bats, scoring 16 runs and conceding 13 runs. The Mets are 8-11 on the road.

Merrill Kelly will get the nod on. Saturday. Kelly was pelted in his recent outing, conceding six runs in 4.2 innings against the Cubs, and was tagged with the loss.

The Arizona Diamondbacks are having an inconsistent season due to the pitching. They were dealt a road sweep at the hands of the Cubs last weekend.

The squad stands at 10-8 at home.

Mets vs. Diamondbacks Pick
Spread Pick for Mets vs. Diamondbacks
- Arizona Diamondbacks +105 (5 units)
The New York Mets have not been able to win games with any consistency all season. It’s been an easy schedule lately, playing against teams with losing records in the Nationals, Angels, and Rockies in their last three series. The Arizona Diamondbacks have been a threat at home, where they stand at 10-8 on the season.
Furthermore, Diamondbacks pitcher Clay Holmes has been shaky in his career against Arizona, surrendering eight runs in seven innings. Diamondbacks pitcher Merrill Kelly is better than his numbers indicate, and this is a prime opportunity to rebound against one of the worst offensive squads in the big leagues. This is a proven pitcher who posted a strong 3.52 ERA and a 1.11 WHIP last season. Kelly held the Mets to three runs in 6.1 innings in the only meeting last season. Take the Diamondbacks at plus money at home.
Over/Under Pick for Mets vs. Diamondbacks
- Over 8.5 (5 units)
I expect this one to have plenty of scoring. While I expect Kelly to contain New York, they are heating up at the plate, scoring 24 runs in their past five games entering Friday evening. Kelly has squandered 16 runs in his last three outings, including six runs in his recent start against the Cubs last week. The Diamondbacks' bullpen is below average with a 4.56 ERA on the season.
In addition, Arizona has a potent offense. They are piling on the runs at home, averaging five runs per game at Chase Field. Also, the over has delivered in each of Kelly's past three outings.
