Best MLB, NBA and NHL parlay picks for Sunday, April 19 using Dimers' "Sweet Spot"

NBA: 76ers +12.5 vs. Celtics (+102)

Game: 76ers vs. Celtics

Time: 1:00 PM ET

We start in the NBA with the first playoff game of the slate on Sunday when the Boston Celtics host the 76ers who advanced through the play-in with a dominant win over the Magic.

They'll face a tougher opponent on Sunday, made clear by the big 12.5-point spread, the second-largest of the opening first round games except for Thunder -14.5 over the Suns.

Still, the Dimers model says this spread is too long, projecting an 11-point win for Boston and a 55% probability that Philadelphia covers.

The 76ers may not be at full strength without Joel Embiid, but have star Tyrese Maxey projected for a big game with 26 points, 4 rebounds and 6 assists, as well as strong contributions from Paul George and VJ Edgecombe.

This Sweet Spot has returned a 2.1% ROI this season over 105 similar bets at this edge. This value is based on the price at Novig prediction market, fair odds would be -122 at our 55% probability, making anything longer than that a value play, such as the -108 odds on FanDuel.

MLB: Guardians vs. Orioles over 7 (-115)

Game: Orioles vs. Guardians

Time: 1:40 PM ET

We move to the diamond next for an afternoon tilt between the Orioles and Guardians for our highest probability play of these three bets.

We project a 59% probability of more than 7 runs being scored in the game, the lowest total of the three games in the series so far.

Orioles starter Trevor Rogers has allowed 2+ ER in three straight starts, with 4 in his last outing, while Guardians starter Joey Cantillo has given up 2 ER in two of four starts so far.

These teams average over 4 runs per game and the Orioles have yet to be shut out as a reliable source of offense so far, and just 2 of their last 10 games have gone under.

Our MLB total predictions are off to a great start, with this Sweet Spot returning a 16.0% ROI over 97 early-season bets.

NHL: Kings +1.5 vs. Avalanche (-113)

Game: Kings vs. Avalanche

Time: 3:00 PM ET

For the final play, we drop the puck in Kings vs. Avalanche, the opening game of this Western Conference series.

These two teams boasted top 10 defenses in the NHL this season, with the Avalanche ranked 1st in the NHL, allowing 0.3 goals less per game than the next best team. Scoring should be tight, even with Colorado's top-ranked offense, with each team expected to start their best goalie.

Los Angeles scored just 2.68 goals per game in the regular season, the fourth-fewest in the NHL, so they'll need their defense to keep this game close.

This is the most profitable Sweet Spot of them all, with NHL puck line plays returning a 20.2% ROI over 128 bets at 3% edge.

Dimers' three Sweet Spot plays in the MLB, NBA and NHL on Sunday, April 19.

Two ways to bet on the Sweet Spot

Bettors looking for a potentially lucrative payout can roll the three Sweet Spot bets above into a single +575 parlay, where a $25 wager would return $143.98 in profit based on the odds at FanDuel Sportsbook.

However, each of these bets comes with its own value and is recommended as a straight wager for the most long-term profitability. This way, if just two of the three bets hit, you'll still walk away with some profit.

For the best of both worlds, consider allocating a small portion of your unit size as a side wager for the parlay alongside the straight bets, rather than investing completely into an all-or-nothing parlay.
