Here are the top sports betting trends for April 21:

NBA: Washington Wizards at Toronto Raptors (8:00 p.m. ET)

Trend: Play on Washington against the spread in road games in April. The Wizards are 11-1 (+9.9 units) over the last two seasons.

The Wizards have been a good bet for handicappers in the month of April and they were an outright underdog winner in Game 1, even though they blew a lead to send the game to an extra period. The Game 2 spread is about the same as the Game 1 number, with the Raptors currently sitting at -4.5 or -5 across the market. It’s fair to say that the Wizards were likely underdogs in most of those games as well.

NBA: Dallas Mavericks at Houston Rockets (9:30 p.m. ET)

Trend: Play against Dallas against the spread in road games against a team with a winning record in the second half of the season. The Mavericks are 1-10 (-10 units) this season.

The Mavericks really scuffled down the stretch against anybody that was excited to step on the court. The Rockets covered in Game 1 and the Mavericks looked like the same out of sync team that they have been for most of the post-All Star Break portion of the season. They’ve been a bad bet for a while now and the number has grown from +5.5 to +6 for Tuesday night’s Game 2.

NBA: Boston Celtics at Cleveland Cavaliers (7:00 p.m. ET)

Trend: Play on Boston against the spread in road games when revenging a loss versus an opponent. The Celtics are 34-15 (+17.5 units) over the last two seasons.

The Cavs coasted to a Game 1 win and cover against the Boston Celtics and are expected to do the same in Game 2 as a double-digit favorite. The Celtics are a young team, but Brad Stevens has done a good job getting them to bounce back at various points throughout his tenure. The Celtics have done that when revenging road losses and that’s the situation that they are in on Tuesday night.

NHL: Vancouver Canucks at Calgary Flames (10:00 p.m. ET)

Trend: Play on Calgary using the money line in games versus division opponents. The Flames are 24-8 (+20.1 units) this season.

The Calgary Flames can take a commanding 3-1 series lead in their best-of-seven set against the Vancouver Canucks with a win on Tuesday night. A big reason why the Flames made the playoffs is because of how they played against Pacific Division foes. The Flames made bettors over 20 units of profit in divisional games during the regular season and a profit so far in the postseason. Calgary is a -115 favorite.

NHL: Tampa Bay Lightning at Detroit Red Wings (7:00 p.m. ET)

Trend: Play against Detroit using the money line in home games with two days rest. The Red Wings are 4-11 (-14.35 units) over the last two seasons.

After getting dominated in both games on the road, the Red Wings return home with a chance to take their second lead of the series with a Game 3 win. Petr Mrazek was great in Game 1 and then followed it up by getting pulled in Game 2. This trend seems coincidental more than anything else, but the Lightning are a road favorite at Detroit, and that’s the most telling aspect of this game and line.

MLB: St. Louis Cardinals at Washington Nationals (7:05 p.m. ET)

Trend: Play against St. Louis using the money line in road games following a day off. The Cardinals are 5-18 (-15.5 units) over the last three seasons.

The St. Louis Cardinals and Washington Nationals open up a big series for both teams on Tuesday night in D.C. Lance Lynn will take the hill against Gio Gonzalez. The Cardinals, for whatever reason, have not played well following travel days over the last three seasons. This could also be a tough spot for them because they historically struggle with southpaws. The Nationals are a slight -115 favorite.

MLB: Baltimore Orioles at Toronto Blue Jays (7:05 p.m. ET)

Trend: Play on Baltimore using the money line in road games against division opponents. The Orioles are 29-16 (+19 units) over the last two seasons.

The Orioles won the AL East last season because of what they did to other AL East opponents. They fully dominated the division and winning on the road in some tough road environments was a big key. The Orioles head to Rogers Centre to take on a struggling Blue Jays team and they have a nice price tag as a plus money underdog on Tuesday night.

MLB: Boston Red Sox at Tampa Bay Rays (7:10 p.m. ET)

Trend: Play against Tampa Bay using the money line in home games. The Rays are 37-50 (-30.55 units) over the last two seasons.

It was a rough season for the Rays last year whether they were home or away. The Red Sox bring a lot of talent with them to the Gulf Coast for Tuesday night’s showdown. Wade Miley has gotten some early betting action for this matchup against Chris Archer and the Rays are favored by as low as -120 in this one. The Rays are just 1-5 at home to start the season.
