Best MLB Parlay Picks Today, Wednesday 06/18 (3-Leg) : Calculated Risk, High Reward

The rationale for betting on Christian Walker to perform under 4.5 in the Batter Hits Runs RBIs market is based on his recent performance data. Walker's overall average for hits, runs, and RBIs in the last five games is 1, 0.6, and 0.6 respectively, which is significantly lower than the line set at 4.5. Furthermore, his performance away from home is even lower, with an average of 0.2 hits and runs, and zero RBIs. Even when considering his performance against the Oakland Athletics, his averages are still below the line. Additionally, Walker is currently on a zero-hit streak overall, suggesting a slump in form. Despite having an eight-game hit streak away from home, his low averages indicate that he is unlikely to surpass the 4.5 line. Therefore, the data suggests that betting under 4.5 is a statistically sound choice.

Freddie Freeman (LAD) Under 2.5 Singles (-526)

The bet on Freddie Freeman for Under 2.5 in the Batter Singles market is a solid choice, based on his recent performance data. Over his last five games, Freeman has averaged 0 singles overall and 0.8 singles at home. His batting average against the Padres is even lower, with only 0.2 singles in the last five games. Furthermore, his overall hit average is 0.8 and at home it's 1.4, both well below the line of 2.5. Despite his impressive overall and home hit streaks, the data shows that the majority of his hits are not singles. Thus, the probability of him hitting under 2.5 singles is high. Therefore, based on these statistics, betting under 2.5 for Freeman's singles is a reasonable choice.
