San Francisco starter Madison Bumgarner only has a 3-3 record Juan Lagares Jersey , but his underlying metrics are much better than that.Oakland's Trevor Cahill has some really drastic home-road splits. He's allowed just two runs in 28 innings this season in Oakland, where he'll get the start tonightPretty unfortunate to drop last night’s first over/under of the second half, as we were in desirable position late in the proceedings before the bullpens let things get away at the very end. We’ll try to get that back on Saturday.Zylbert’s 2018 MLB Over/Under Betting Record: 63-41-3, +17.75 unitsYesterday’s Result: Twins-Royals Under 8.5 (loss)*Each bet graded as if it were to win 1 unit>> Follow Matt Zylbert in The Action Network App to get free alerts on all his MLB bets during the season.San Francisco Giants @ Oakland Athletics | O/U: 7.5Over/under: 7.5First pitch:聽9:05 p.m. ET (MLB Network)Probable pitchers:聽Madison Bumgarner (3-3, 2.90 ERA) vs. Trevor Cahill (1-2, 3.10 ERA)In the first four Bay Bridge Series聽contests, including last night’s 5-1 San Francisco victory, the under has gone 2-1-1 and the teams have scored no more than eight runs.Perennial NL Cy Young candidate Madison Bumgarner played a hand in one of those matchups eight days ago, as he beat Oakland with six solid innings of one-run ball. That’s been a theme for the former World Series MVP in 2018 ever since coming back from a broken pinky that cost him the first two months of the campaign.Saturday MLB Sharp Report: Pros Betting Giants-A鈥檚, 4 Other GamesRead nowThrough his first eight starts this season, Bumgarner is only 3-3 but he’s notched a sweet 2.90 ERA and .225 batting average against. He’s pitched into the sixth inning or deeper in every assignment, and in all but two of those, he surrendered three runs or fewer. Thus, it’s no surprise that the under has gone 5-2-1 when Bumgarner has toed the rubber.The last time the Giants’ ace pitched at the Oakland Coliseum — a little more than two years ago — things did not go so peachy, as he was tagged for four runs in 6.1 frames. However, that involved the highly unusual circumstance of Bumgarner batting for himself in an American League park Travis d'Arnaud Jersey , which is something we won’t have to worry about this evening.Plus, he actually holds good career numbers against some of Oakland’s key hitters, with Khris Davis, Matt Olson, Matt Chapman, Marcus Semien and Mark Canha being a combined 4-for-29 (.138) off the San Francisco left-hander. The A’s as a team are also tied for the third-lowest batting average versus southpaws (.233) in the AL.>> Get a 7-day free trial to access more premium MLB articles like this during the season.It looks like we can count on Bumgarner to be his steady self tonight, but can veteran journeyman Trevor Cahill keep up? Well, if he’s going to go down, it will be in the fortress where he’s etched his best work over the years.This is Cahill’s fourth year with the A’s (second stint), and in each of the first three, he finished with decisively better numbers when taking the mound in his home ballpark.Those glaring home-and-road splits have once again been on display this year, as Cahill has allowed a mere two runs combined in his four home assignments, spanning 28 total innings (0.64 ERA). When he’s pitched on the road, he’s registered a 5.92 ERA. Cahill has made more starts in Oakland (54) than anywhere else in baseball and it’s clear he likes working there (career 25-18 record and 3.03 ERA).Unfortunately, I acted just a bit late on this total, as the line has dropped to 7.5 in most places. Look around to see if you can get it at 8 Noah Syndergaard Jersey , but the under at 7.5 is still a nice play on this Saturday night.Play: UNDER 7.5/8Editor鈥檚 note: The opinion on this game is from the individual writer and is based on his research, analysis and perspective. It is independent of, and may not always match with, the algorithm-driven Best Bets from Sports Insights. Count Boston Red Sox owner John Henry among those who believe spending more money aids in building a winning team.According to ESPN.com's David Schoenfield, Henry suggested as much Monday:"I think the Baltimore payroll was double what the Tampa payroll was last year. Close to double. There is a correlation, I'm sure there is a correlation, but it's not as perfect. It's very difficult to predict things in baseball, to predict player performance. Spending more money helps."That may seem obvious, but it flew in the face of what MLB Commissioner Rob Manfred said previously, as he opined, "I reject the notion that payroll is a good measure for how much a team is trying or how successful that team is going to be."There has been no shortage of debate regarding the importance of spending, since the top available free agents, Bryce Harper and Manny Machado, remain unsigned at the start of spring training.Spending yielded mixed results in 2018. The Red Sox won the World Series with the top payroll at over$227 million, and the Los Angeles Dodgers won their second consecutive National League pennant with the third-highest payroll at a shade under $200 million.The Chicago Cubs (fourth), New York Yankees (sixth) and Houston Astros (ninth) all made the playoffs.Half the teams in the top 10 did not reach the postseason http://www.metsfanproshop.com/authentic-tim-tebow-jersey , though, as the San Francisco Giants (second), Washington Nationals (fifth), Los Angeles Angels (seventh), St. Louis Cardinals (eighth) and Seattle Mariners (10th) all fell short.Meanwhile, the Oakland Athletics reached the playoffs with the league's third-lowest payroll.Selectivity in free agency played a huge role in the Red Sox's World Series win. Like Harper and Machado this year, slugger J.D. Martinez went unsigned into spring training in 2018. Boston picked him up, and he had a huge year with a .330 batting average, 43 home runs and 130 RBI.The Red Sox are once again set to enter the season with MLB's highest payroll, while the Cubs, Yankees and Dodgers are the next three in line. All four of those teams are expected to make the playoffs.Spending may not be the only indicator of team success, but the Red Sox have shown over the past 15 years that allocating big money wisely can go a long way toward building championship-winning clubs.
