The Boston Red Sox (66-58, 29-31 Home) will try to get back on track tonight when they host the Arizona Diamondbacks (66-59, 30-32 Away) at Fenway Park. Fans can follow the action on MLB.TV once the game gets underway at 7:10 p.m. EST.

Boston is coming off a road trip that did not go too well for them as they lost five of seven, going 1-3 vs. Toronto and 1-2 vs. the Pirates. Arizona lost the series finale to the Braves in Atlanta Sunday, but won the first two games in the series 2-0 and 10-3.

The Red Sox are expected to turn to Alec Gamboa to get things started. A reliever, Gamboa has appeared in nine games this season (0 starts) with a 1.59 ERA and a 1.12 WHIP. Teams have hit .233 against him. He’s appeared in four games at home (10 1/3 innings) where he has a 2.61 ERA and a .256 OBA. The three earned runs he has allowed all came at home.

As for the D-backs, Arizona is scheduled to go with Mitch Bratt. Bratt has a 3.74 ERA and a 1-1 record in seven starts with a 1.40 WHIP. Teams have hit .230 against him. However, he has struggled on the road, where he is 0-1 in four starts with a 5.63 ERA and a .250 OBA.

Our Boston Red Sox vs Arizona Diamondbacks Prediction

For a time, Boston was the hottest team in baseball and one no one wanted to face. But they have since cooled down. The lineup isn’t making a ton of noise lately (.244 over the last week, next to .271 for the D-backs). But both have averaged right around four runs per game (Arizona—21 over five games; Boston—25 over six). Bratt has been a solid pitcher, so I don’t see the Red Sox going off on him. Boston’s bullpen has the lowest ERA in baseball, so I don’t see the D-backs lineup teeing off either.

Our Arizona vs. Boston Pick: UNDER 9
