Mets Looking to Stay Competitive on the Road

One of the biggest strengths for New York entering this game is pitching consistency compared to Arizona. The Mets hold advantages in ERA, WHIP, opponent batting average, and strikeouts. Clay Holmes has also been excellent individually with a 1.69 ERA and a WHIP below 1.00 entering this road matchup.

Arizona Trying to Recover After Tough Stretch

Arizona enters Saturday with a 17-19 overall record and a 10-8 mark at home. The Diamondbacks recently lost to Pittsburgh by scores of 4-2 and 1-0 after previously defeating the Pirates 9-0. Before that series, Arizona also recently lost to the Cubs by scores of 8-4 and 2-0. The Diamondbacks have struggled to generate offense consistently during this recent stretch, scoring two runs or fewer in three of their last four losses.

Arizona has produced a .242 batting average with 161 runs, 288 hits, and 35 home runs this season. The Diamondbacks also own a .302 on-base percentage and a .402 slugging percentage. On the mound, Arizona carries a 4.78 ERA and a 1.37 WHIP while opponents are batting .252 against them. The pitching staff has recorded 266 strikeouts this year.

The biggest strength for Arizona has been overall offensive production compared to New York. The Diamondbacks have scored more runs while also holding advantages in batting average, slugging percentage, and home runs. However, Arizona’s pitching staff has struggled heavily overall, and Merrill Kelly’s numbers entering this matchup have been particularly difficult.

New York Mets vs Arizona Diamondbacks Picks and Prediction

New York Mets vs Arizona Diamondbacks Pick

  • Pick: New York Mets Moneyline

New York gets the edge in this matchup because of the clear pitching advantage entering the game. Clay Holmes has been outstanding this season with a 1.69 ERA and a 0.98 WHIP, while Merrill Kelly enters with a 9.95 ERA and a 2.32 WHIP. Arizona’s offense has been stronger overall statistically, but the Diamondbacks have struggled recently during this losing stretch. The Mets also hold a significant advantage in strikeouts and overall pitching consistency.

New York Mets vs Arizona Diamondbacks Total Pick

  • Pick: Take the over if the total is set at 8.5

I would lean toward the over because Arizona’s pitching numbers have struggled throughout the season, and Merrill Kelly has allowed six home runs in only 19 innings. The Diamondbacks offense has also produced 161 runs and 35 home runs this season, while New York has recently been involved in games finishing 10-5 and 6-2. Arizona’s pitching issues create opportunities for scoring on both sides.

Final Score Prediction: New York Mets 6 – Arizona Diamondbacks 4
