Baltimore Orioles vs Seattle Mariners Picks

T-Mobile Park

<p>The end of a streak means that it is time to start a new one, and that is what the Seattle Mariners will look to do this afternoon in the rubber game of their series with the Baltimore Orioles.</p>
<p>Yesterday, Seattle’s eight-game win streak came to an end with a 1-0, 10-inning loss, as their bats went dry after scoring nine runs in Friday’s series opener.</p>
<p>Still, the Mariners (63-53, 34-27 home) have a chance to close out the weekend with a series win over the Orioles (72-45, 36-22 away), who maintained a two-game lead over the Tampa Bay Rays in the AL East with the win.</p>
<p>This afternoon’s series finale sees two righties take the mound, with Kyle Bradish going for Baltimore and rookie Bryce Miller going for Seattle. Will we see another tight, low-scoring contest, or will one side break out the bats like the M’s did on Friday?</p>

<p>If these odds hold, the Orioles will close as a road favorite for the 17th time this season.</p>
<p>That is a small amount compared to other division leaders like the Atlanta Braves and Los Angeles Dodgers. But it is a spot in which Baltimore has thrived this season, going 12-4 (.750) as a road favorite. </p>
<p>The only other MLB team with that kind of success is the Cincinnati Reds, who are 6-2 as a road favorite this season.</p>
<p>That said, this is also a strong spot for the Mariners. They are 6-3 in Miller’s home starts, and they are 7-3 in their last ten games following a loss. </p>
<p>The Orioles, meanwhile, are just 4-5 in Bradish’s last nine road starts after winning in his first three road starts this season. </p>
<p>Also, Miller’s splits swing things favorably for Seattle, while the same can’t be said for Bradish’s splits and the Orioles’ hopes of the road series win.</p>
<p>On the road, Bradish is 4-3 with a 4.06 ERA in a dozen starts, compared to 3-3 with a 2.18 ERA in nine home starts.</p>
<p>Miller, on the other hand, is 5-2 with a 3.49 ERA in nine home starts this season, compared to 2-2 with a 5.15 ERA in seven road starts.</p>
<h2 id="7d113">Baltimore Orioles vs Seattle Mariners Prediction and Best Bets</h2>
<p><strong>Orioles vs Mariners Best Bets:</strong> Mariners ML (-105 at <a href="/best-online-sportsbooks/bovada/">Bovada</a>) &amp; Julio Rodriguez to record an RBI (+160 at Bovada)</p>
<p>This one is a real toss-up, but the Mariners ultimately get the nod here. The Orioles have the best road record in the National League, but the Mariners are 8-3 in their last 11 home games, so they will be up to the task.</p>
<p>Rodriguez went 2 for 5 with a homer and four RBI in Friday’s 9-2 win, but he was hitless in five at-bats yesterday.</p>
<p>Each of the previous three times he went hitless, Rodriguez homered and drove in at least one run in the next game. In addition to being +160 to drive in at least one run, he comes in at +450 to deliver a dinger today.</p>
