Rosters have officially expanded and a lot of teams have simply called up relief reinforcements or are going to take a look at some mid-tier starting pitching prospects and minor league veterans. In other cases, there will be some new hitters chomping at the bit to show the manager and the front office what they can do at the big league level. You can bet that we’ll have some of these low-priced options in there at some point. Will today be that day? Let’s see what the DFS landscape has to offer.

Remember that our column here at BangTheBook is centered exclusively on finding value. You know who the good players are. So does everybody else. It’s those under-the-radar guys that you pair with those high-salary players that allow you to come out on top.

DraftKings or FanDuel are the industry leaders in ease of use and safe, free transactions. Use these tips and the tips from our daily radio show to improve your abilities and fill out the winning lineup. Our MLB daily fantasy tips and suggestions article is different in that we’re not looking for the top scorers, but for the best values so that you can get the edge that you need in order to save money for the game’s best players.

The salaries listed are from DraftKings:

Here are the top teams to stack for September 2:

Arizona - It’s not easy to like anything about the Diamondbacks at this stage of the game with their front office woes and manager scapegoating. But, they draw left-hander Jorge de la Rosa today and that should be enough for a D-backs stack. It’s been a rough year for the veteran southpaw with a 5.09 ERA, a 4.99 FIP and a 4.78 xFIP. About the only thing the Diamondbacks have done right this season is bash lefties, which they do better than just about anybody else in the league by wOBA. It also doesn’t hurt that Arizona is at Coors Field tonight.

Baltimore - Last time Chad Green and Dylan Bundy got together, Green got the best of his fellow rookie in a game at Yankee Stadium. The script is flipped tonight, as the teams meet at Oriole Park at Camden Yards. Green’s 5.12 FIP stands out because the home run rate is off the charts for the 25-year-old. He’s given up 11 long balls in 44 innings and we all know about the power potential of this Baltimore lineup.

St. Louis - I’m a big fan of what Anthony DeSclafani has been able to achieve this season, but I do have some regression concerns and that’s where a matchup against the Cardinals comes into play. DeSclafani is carrying a 79.8 percent LOB% on the season. It’s sustainable if he keeps up his strikeout rate, but he’s never been a strikeout artist, so we’ll have to see if he can keep a top-five offense by wOBA against RHP at bay.

Here are the top value hitters for September 2:

Odubel Herrera ($2,000) - It looks like the DraftKings price algorithm has screwed up today with the Philadelphia Phillies. Joel de la Cruz has a 4.66 ERA and peripherals over 5.00, but the Phillies’ key bats are all priced really low. You can take your pick between Herrera and Maikel Franco, but we’ll focus on Herrera, who has a .299 batting average and all 13 of his home runs against right-handed pitching. He looks like the ideal streaming candidate.

Danny Valencia ($3,400) - Platoon guys get a reputation because they bat really well against certain splits, but also because they’re capable of hitting the best pitchers that those splits have to offer. David Price is on the bump for Boston tonight, but we should trust Valencia’s ability to do work against him, just like he does against most other southpaws. Valencia is slashing .343/.410/.571 on the season against lefties, which is similar to last season’s production.

Wil Myers ($3,900) - It’s a bit of a lofty price to pay, but Wil Myers has carried great production against lefties throughout the season and he gets a kid still learning on the job in Julio Urias on Friday night. Myers has hit eight of his 24 home runs with the platoon advantage and owns a .296/.377/.539 slash against left-handed throwers. The Padres offense has been bad overall this season, but their production against lefties has been pretty solid much of the year.

Here are the top value pitchers for September 2:

Alex Reyes ($6,400) - From a pure stuff standpoint, Alex Reyes might be third behind Noah Syndergaard and Carlos Carrasco tonight. He’s also priced much lower than those guys and draws a favorable matchup against the Cincinnati Reds. Reyes worked 4.2 innings against Oakland last time out and flashed some of his brilliance, but he wasn’t very economical with his pitches and was pulled early. Expect better tonight with those first-start jitters out of the equation.

Jameson Taillon ($8,400) - It’s been a good season for Pirates rookie Jameson Taillon, who returns to the big leagues after a procedural move to get some reinforcements up for the Pirates earlier in the week. Taillon has a 3.39 ERA with a 3.70 FIP and a 3.24 xFIP over his first 13 starts and has a decent strikeout rate. The best attribute is that he hasn’t walked guys and the Brewers generate a good chunk of their offense from free passes. They can’t do that here tonight.

Danny Duffy ($9,100) - You would think that the right-handed-heavy Tigers would be slaughtering left-handed pitching like they did last season, but that really hasn’t been the case. In this spot, the Royals send Danny Duffy to the mound for what has suddenly become a huge series with massive playoff implications. Duffy has been terrific as a starter this season, posting a 3.01 ERA in 125.2 innings of work with 128 strikeouts. He’s locked in and capable of throwing a gem, even against this lineup that, theoretically, should pose problems.
