Hollywood Park selections 10/19

Last night of night racing here. Looks like a great card in races 1-4..the rest don’t seem very competitive. I’d go for the pick 3 in races 1-3 and 2-4 and even the pick 4 here. 
Also check out these for your ROI needs:
race 2: #1 Mikethedealer: Trainer Alcala has great ROI of 510% with horses making their first route race   
race 5:  #10 Warren’s Gecko: Jockey/trainer combo of Arambula/Guiterrez have won at 20% clip and 35% in money in last 60 days, covering 20 races, with positive ROI.  
race 6: #5 Courtside Action is best of these ROI selections. Trainer DeLeon has won at 36% rate with horses coming off a win, and 50% in money, good ROI here..all this from a 36 race sample. 
Race 8: Candace Gold: Trainer Papaprodromrou has great ROI of 288% in 36 races, despite a 6% win rate and 34% in the money.
