Arizona Diamondbacks vs. Seattle Mariners – 9/13/20 MLB Pick, Odds, and Prediction

The Seattle Mariners and the Arizona Diamondbacks meet in MLB action from Chase Field on Sunday.

The Seattle Mariners will look to build off of a 7-3 win over the D-Backs on Saturday. Jose Marmolejos went 2 for 4 with a home run, a double and three RBIs while Luis Torrens had a double and two RBIs. Ty France added a solo home run while going 3 for 4 at the dish and Kyle Seager had an RBI as well to cap off Seattle’s scoring as a team in the win. Phillip Ervin went 2 for 4 with a double while Dylan Moore added a base hit as well to round out the offense for Seattle in the win. Justus Sheffield got the win to improve to 3-3 on the year after allowing two earned runs on five hits while striking out seven over seven innings of work. Justin Dunn will start 3-1 with a 4.09 ERA and 25 strikeouts this season. This will be Dunn’s first career start against Arizona.

The Arizona Diamondbacks will try to rebound from their loss to Seattle on Saturday. Wyatt Mathisen had two RBIs while David Peralta added an RBI as well to finish off Arizona’s scoring as a team in the losing effort. Nick Ahmed went 2 for 4 and Christian Walker had a double while Eduardo Escobar, Tim Locastro and Pavin Smith all had base hits to finish off Arizona’s offense as a team in defeat. Zac Gallen took the loss, falling to 1-2 on the year after allowing seven runs on seven hits while striking out six over five innings of work. Luke Weaver will start here and is 1-6 with a 7.12 ERA and 41 strikeouts this season. This will be Weaver’s first career start against Seattle.

Seattle is 30-64 in their last 94 road games and 10-26 in their last 36 games against the NL West while the over is 5-1 in their last 6 interleague games. Arizona is 15-6 in their last 21 interleague games and 5-2 in their last 7 games against the AL West while the under is 13-3 in their last 16 games against a team with a losing record.

Saturday’s game barely got over the total, but I’m leaning towards Sunday’s game to be a bit different. Weaver’s pitched better after a rough start to the year, allowing just two runs in five innings in his last start. Dunn on the other hand has a 1.00 ERA across his last three starts and is looking like one of the next bright, young arms in that rotation. I’ll side with a lower scoring game here so I’ll back the under as my free play for this game but my stronger play is on the side and I have that available as a premium pick that you can find here.
