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

Today’s two best Underdog Fantasy MLB Pick'em plays are Jake Irvin over 1.5 walks allowed and Patrick Sandoval over 1.5 walks allowed. 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.

 

 

 

Jake Irvin HIGHER THAN 1.5 Walks Allowed

Since returning from a shoulder strain, Irvin has dealt with some command issues. Take a look at some of his numbers before his trip to the injury list, compared to afterwards:

 

BB%

O-Swing%

Zone%

F-Strike%

Pre-Injury (11 GS)

12.1%

26.2%

53.4%

61.4%

Post-Injury (9 app.)

9.6%

24.6%

51.8%

64.1%


 

Irvin has walked 13 batters over his last 19 IP, and in the month of September, the Cardinals have the 11th-highest walk rate (9.2%) against RHP. Since returning from injury, he’s walked multiple batters in eight of his nine appearances!

Patrick Sandoval HIGHER THAN 1.5 Walks Allowed

Sandoval has walked batters in all but two starts this year, not to mention doing so in 10 straight outings! His first-pitch strike rate over his last four outings has dipped to 47%, and his walk rate in the second half (11.3%) is more than double his mark before the All-Star break (5.3%). It’s going to be a tough matchup for the Boston southpaw today, as this Rays team has a .361 OBP, .332 wOBA, and 112 wRC+ against southpaws this month. Oh, it’s probably also worth noting that the Rays have a 10.2% walk rate during that stretch, which is the eighth-best mark in the MLB.
