The Atlanta Braves and Miami Marlins wrap up a four-game NL East set at loanDepot Park on Thursday, May 21, and I’ve got a pair of MLB picks for the series finale.

My top Braves vs. Marlins predictions call for Atlanta to eke out a low-scoring win over Miami tonight. 

Who will win Braves vs Marlins today: Braves moneyline (-136)

Atlanta Braves starter Spencer Strider has allowed a single run on just four hits while holding opposing hitters to a pedestrian 27.3% hard-hit rate across his past two starts, and I’m anticipating him keeping the good times rolling against a ho-hum Miami Marlins lineup.

The Marlins rank 19th in wOBA against right-handed arms, and Miami also ranks 20th in both overall ISO and xwOBA over the past two weeks.

Of course, Atlanta has been a force at the dish all season and ranks second in both runs per game and wOBA against righties. 

Covers COVERS INTEL: Braves lefty Spencer Strider has a 1.13 ERA while holding the Marlins to a .600 OPS at loanDepot Park.

Braves vs Marlins Over/Under pick: Under 7.5 (+100)

In addition to Strider sliding back into elite form, Miami righty Sandy Alcantara has also been excellent this season and allowed two earned runs or fewer in seven of 10 starts for a solid 3.53 ERA, 1.26 WHIP and 3.31 xERA.

As a result, I’m anticipating the righty keeping the Atlanta bats off balance enough to keep this total Under the number Thursday night. 

The Braves have dipped to just 4.5 runs per game with a 14th-ranked xwOBA over the past two weeks, after all.

He loves to lean on his rolodex of idioms to offset his inner nerd. When it comes to wagering, he throws down on anything that catches his eye at bet365, Betway and BetVictor. He also keeps a close eye on CoolBet because the polar bear brand often has outlier NHL and NFL moneyline prices.

After teaching a myriad of courses and subjects, he found a groove delivering fun lessons to exceptional learners in non-traditional classroom environments. If his decade-plus teaching run taught him anything about sports betting, it’s to stay the course and use the summer – or offseason – to refresh and prepare to be better in the year to come.
