A week ago, the Boston Red Sox were sitting in first place in the American League East, two games ahead of Tampa Bay. Things have taken a nasty turn for Boston, as it has lost a season-high five straight games since then - including three against the Rays - and now trails Tampa Bay by a game. The Red Sox look to stop the bleeding Wednesday as they visit the Detroit Tigers for the middle contest of their three-game series. Should you expect Boston to record the first win on their 10-game road trip, or is there value on Detroit to post its third straight victory and bring a return on the money line?

The latest MLB odds for Wednesday from Caesars Sportsbook list the Red Sox as -145 favorites (risk $145 to win $100) on the money line. Other MLB lines of note include the New York Mets at -153 against the Miami Marlins and the Washington Nationals as slight money-line favorites (-111) versus the Philadelphia Phillies. Before making any MLB picks or predictions on those games or others, you need to see what the SportsLine Projection Model has to say.

Top MLB picks for Tuesday, August 4

The model likes the San Francisco Giants at -177 on the money line against the Arizona Diamondbacks. San Francisco is 10-2 against Arizona this season and looks to improve that record behind ace Kevin Gausman (9-5, 2.35 ERA). The 30-year-old right-hander, who was an All-Star for the first time in his career this year, is winless in his last three starts but has beaten the Diamondbacks twice already in 2021. After recording nine strikeouts over five scoreless innings at Arizona on May 25, Gausman allowed two runs and four hits in eight frames at home on June 17.

Alex Dickerson has enjoyed facing the Diamondbacks this year, as five of his six hits in the season series have gone for extra bases. The 31-year-old outfielder was a main contributor in Monday's 11-8 victory, recording his second triple of 2021 - both against Arizona - and second career grand slam. Wilmer Flores has three home runs and seven RBIs versus the Diamondbacks this season and notched two of San Francisco's seven hits in Tuesday's 3-1 loss.
