MLB Picks, Predictions & Best Bets Today, 8/21 San Francisco Giants vs. Boston Red Sox Prediction: Friday, August 21st
At this point in the season some teams are just running out the clock and that's where the Giants find themselves on this road trip to Boston. Logan Webb is expected to pitch after dealing with back tightness this week so you wonder how long he will be out there. Webb is having a terrific August allowing just two earned runs over his last 20 innings pitched.
On the Boston side Sonny Gray will take the mound with his 0.95 ERA in the month of August. Over 19 innings pitched he has given up just two earned runs and four walks while piling up 19 strikeouts. Gray is where we find our first wager as the Giants over the past two weeks are really whiffing at the plate. Their team 24.8% k-rate is the 5th highest in MLB during that time span and on top of that the team is hitting a .118 isolated power mark and a .254 BABIP. The lack of offense will keep Gray in the game at least six innings tonight and his strikeout prop is 5.5. I am taking the over on that all day long!
On top of the strikeouts for Gray I just really like Boston today as I fear Webb won't be feeling 100% and that creates a misprice in the market today. The Sox to win on the Run Line is priced up and that's great considering the Giants are one of the leagues worst road teams at 23-42 on the season. Take the Sox to win and win handily tonight.
