It's a wide-open landscape on Tuesday with just a few studs pitching, so we could see scores soaring. It's deadline day, too, so contenders could be adding pieces and gearing up for the stretch run. Keep an eye on the news so you don't roster someone who is dealt that day and doesn't play.
Here's a look at Tuesday's top streaming options, focusing on players rostered in less than 50 percent of ESPN leagues.
Pitchers to stream
Kolby Allard (R), rostered in 9 percent of ESPN leagues, Atlanta Braves vs. Miami Marlins: The 20-year old prospect is being summoned to make his major league debut. Allard profiles as a mid-rotation starter long term, but remember many thought that about Aaron Nola. The reason he isn't considered ace material is fastball velocity. Along with his 90 mph heater, Allard throws a plus curve and change. The southpaw comes to the bigs after twirling a 2.80 ERA and 1.21 WHIP for Triple-A Gwinnett. Allard fanned only 87 in 109 innings, limiting his ceiling. If Allard can learn to miss more bats, he can follow in Nola's footsteps and become a top-end starter. For his debut, Allard draws the Marlins. They're allergic to homers ... and hits. They are 27th in wOBA and 29th in ISO this season. Allard's recall is in part to give Sean Newcomb an extra day's rest after his 134-pitch near-no-hitter last time out, so there's no guarantee he'll remain in "The Show," However, Atlanta has a double-header next Monday, so he could stay up for at least one more start.
Dereck Rodriguez (R), 42 percent, San Francisco Giants at San Diego Padres: Rodriguez has quietly emerged as a solid arm in the wasteland that has become the streaming landscape. He's really surging of late, with a 1.53 ERA and 0.91 WHIP in his past 35 innings, which include five starts and a three-inning relief stint during a 13-inning game. The Padres are 30th in wOBA and ISO against righties this year, so Rodriguez is an auto-start.
Trevor Cahill (R), 17 percent, Oakland Athletics vs. Toronto Blue Jays: He has been a bit wobbly off the disabled list, with a 5.65 ERA and nine walks in 14 innings, but the first one of those starts was in Houston. He has done his best work at home this year, so getting back there might get him back on track. He has a 0.80 ERA and 0.80 WHIP in 34 home innings this year. The Jays' offense is above average against righties, but they dip a bit on the road, with a .735 OPS.
The Rays are using Ryne Stanek to open against the Angels. The former first-rounder has been fantastic this year (2.43 ERA, 1.03 WHIP), but it will be a couple innings at most, so I still have an Angel recommended in the hitting portion of Tuesday's notes.
Projected game scores
Alex Avila (L), under 1 percent, Arizona Diamondbacks vs. Texas Rangers (RHP Bartolo Colon): Avila is coming around a bit in July, hitting .333 with a couple homers and seven RBIs. All 35 of his extra-base hits since the start of the past year have come against righties. Colon's July has been the opposite. He has a 5.96 ERA in four starts with five more earned runs (17) than strikeouts (12). Start all of your Diamondbacks.
Yonder Alonso (L), 41 percent, Cleveland Indians at Minnesota Twins (RHP Kyle Gibson): Alonso gets a repeat entry here, as I recommended him last week. He gave us only 1-for-4 last Tuesday, but if you were inclined to stick with him for the rest of the week, you got hits in each of his next five games, good for a .438 average, and three homers. His July looks a lot like his early season breakout from last year, so while Gibson isn't a pushover matchup, I like Alonso's .273/.347/.486 line against righties.
Ian Kinsler (R), 46 percent, Los Angeles Angels at Boston Red Sox (HP undecided): Kinsler's bat is finally showing life the past two months. He had eight homers in June, and his slash line has soared in July at .320/.393/.467. He'll face Ryne Stanek and then a flood of relievers. Kinsler could get some lefties, as he has a sharp reverse platoon this year, but the .218 BABIP against lefties is due to push back toward the mean.
Maikel Franco (R), 47 percent, Philadelphia Phillies at Boston Red Sox (LHP Drew Pomeranz): Are we finally getting the breakout? Franco's .801 OPS is his highest in three years, and with 17 home runs already, he is on pace for a new career high. He hasn't done much against lefties this year, but this is a play against Pomeranz. He has had nearly a 200-point platoon split this year, with a .970 OPS against righties, including nine homers in 163 plate appearances.
Jorge Polanco (B), 7 percent, Minnesota Twins vs. Cleveland Indians (RHP Trevor Bauer): This the Hail Mary play of the day. I actually have an outfielder coming up with a lower roster rate, but Polanco facing Bauer makes this the bigger long shot of the two. Statistical folks, get ready to cringe ... Polanco has three homers against Bauer in 16 plate appearances, and I'm calling my shot with him getting his first of the year on Tuesday!
Matt Davidson (R), 14 percent, Chicago White Sox vs. Kansas City Royals (LHP Danny Duffy): Right-handed Joey Gallo has been solid against lefties this year, with a .250/.363/.529 and five homers in 80 plate appearances. Duffy has allowed 19 of his 20 HRs against righties with a 163-point platoon split, as they hold a .791 OPS in 466 plate appearances.
Yairo Munoz (R), 12 percent, St. Louis Cardinals vs. Colorado Rockies (RHP Jon Gray): Munoz has had an up-and-down year with monthly OPS totals of .367, 1.094, .616, and 1.030. He doubled his home run total in July with three, too. He has been about neutral platoon-wise with a .782 OPS against righties (.853 vs. lefties) this year. The pickings were slim in the middle, so I had to go against Gray, who has been sharp in two home outings since being recalled from Triple-A with a 1.26 ERA, 0.63 WHIP and 12 strikeouts in 14 innings.
Michael Conforto (L), 54 percent, New York Mets at Washington Nationals (RHP Tanner Roark): I pushed the roster rate threshold a bit here to highlight Conforto, who looks healthy and could be poised for a strong stretch run. His shoulder injury was supposed to cost him all of April, but instead, it cost him a week, and he has played in 94 of the team's 103 games this year. The shoulder was likely depressing his numbers through the first half, though, as he managed just a .710 OPS. Since the break, he's looking like peak Conforto again, at 1.178 OPS with three homers in nine games. Conforto should be rostered in at least 75 percent of leagues right now. Roark is coming off his best start of the year, but eight shutout innings still dropped his ERA to only 4.55.
Enrique Hernandez (R), 24 percent, Los Angeles Dodgers vs. Milwaukee Brewers (LHP Wade Miley): Hernandez has always been a platoon guy with a career 202-point platoon advantage against southpaws. This year he's toting a modest .697 OPS against them, but the .216 BABIP is doing a lot of the work there, and he still has seven homers in 145 PA (.193 ISO). Don't be fooled by Miley's 2.01 ERA in five starts, as it comes with more walks (13) than strikeouts (12).
Brian Goodwin (L), under 1 percent, Kansas City Royals at Chicago White Sox (RHP James Shields): Goodwin was dealt to the Royals and found some playing time, which he has parlayed into some early success. It's obviously a tiny sample, but he's 8-for-17 with a couple extra-base hits in five games. The 27-year-old outfielder has been stuck in the crowded Nationals outfield and now gets a runway to see how well his skills can play with regular time. Shields hasn't been too bad this year overall, but his rough games are still especially rough, as he has five starts with at least six runs allowed.
Hitter matchup ratings
Hitter ratings account for the opposing starting pitcher's history (three years' worth) as well as ballpark factors. "LH" and "RH" ratings account only for left- and right-handed batters, respectively.
Weighted on-base average (wOBA) is the primary statistic used in the calculation. Ratings range from 1 to 10, with 10 representing the best possible matchup, statistically speaking, and 1 representing the worst. For example, a 10 is a must-start rating, while a 1 should be avoided (if possible); a 1-2 is poor, 3-4 is fair, 5-6 is average, 7-8 is very good and 9-10 is excellent.
