Looking for the best Underdog Fantasy MLB picks today? Our Underdog MLB Pick'em predictions for Sunday, April 5, 2026, spotlight two MLB player props worth targeting on today’s action-packed MLB slate. Matt Olson’s hits+runs+RBI and Trea Turner’s runs scored lines both come with clear situational edges backed by current form, matchup data, and recent trends. If you are building your Underdog Pick'em entry for tonight's MLB slate, here is the full case for where we land on both and why the numbers set up the way they do.

What are the Best Underdog MLB Pick'em Picks Today?

Today’s two best Underdog Fantasy MLB Pick'em plays are Trea Turner over 0.5 runs scored and Matt Olson over 1.5 Hits+Runs+RBI. Both props are supported by matchup data, current streaks, and favorable line construction heading into an action-packed day of baseball. Read below for the complete analysis on each.

 

 

 

Matt Olson OVER 1.5 Hits + Runs + RBI

Through four April games, Olson is slashing a cool .375/.444/.938 with a total of six hits, four runs scored, and five RBI. He’s posted a strong .333 average and 1.093 OPS against right-handed pitching thus far in 2026, and he will take on a RHP that has had his fair share of struggles against lefties in recent memory.

Five of the six hits Brandon Pfaadt allowed in his debut came to left-handed hitters, and when you look back to the 2025 season, he surrendered a .451 SLG, .333 wOBA, and 12.5 K-BB% to lefties. Furthermore, this game will be played at Chase Field, and Pfaadt has a career 4.66 ERA at home.

Olson is swinging a hot bat, and I like him to be a key part of Atlanta’s offensive production today against Pfaadt.

Trea Turner OVER 0.5 Runs Scored

Turner has recorded a run scored in six of eight games this season, including doing so in three straight! He’s had a hot start to the month of April, going 6-for-12 with a .571 OBP and five runs scored. He’ll take on Tomoyuki Sugano on a relatively warm April day in Colorado, and Turner has posted a .935 OPS against right-handed pitching.

As a team, the Phillies have the fifth-highest wOBA and seventh-highest batting average against RHP this season, so as the leadoff man for a good offense at Coors Field, I like Turner to cross the plate in this one.
