Arizona Diamondbacks vs. Martín Pérez

Although Perez has had two decent outing over his last three games, he’s been a gascan for primarily the entire season. Righties are hitting .384 against him and lefties haven’t been too shabby either at .294. Not only that, but he’s allowing a righties a .457 wOBA and left-handers .364. He has a 7.08 ERA on the year and an atrocious WHIP north of two.

Paul Goldschmidt is the obvious choice when starting this stack due to how good he’s been against left-handers. Goldschmidt has hit over .300 for six straight years and he’s currently making it seven sitting at .316. Steven Souza Jr. has really begun to make his presence with the Diamondbacks felt as he’s hitting .333 over his last 10 games, and he also happens to hitting .324 versus southpaws on the year. A.J. Pollock has elite marks in the OPS and ISO categories versus lefties at .990 and .365 respectively.

Moving on to the secondary plays, Ketel Marte , Daniel Descalso and Nick Ahmed are all firmly in play here. Each player has been surprisingly good versus southpaws this season. Marte has flashed a ton of power against them which hasn’t been something he’s known for. He’s hit five of nine homers versus lefties but he’s done so in 30 less games, which has allowed him to accrue an impressive .266 ISO. Ahmed might not even start, but he’s very nice, cheap value if he plays. He has hit seven bombs off of left-handers and has a .368 wOBA as well. Descalso could be the most surprising of all because he himself is a lefty. He has a .379 wOBA himself and has normally hit in the middle of the Diamondbacks lineup, providing him with a bunch of run producing opportunities.

Primary Option(s): Paul Goldschmidt , Steven Souza Jr. , A.J. Pollock

Secondary Option(s): Ketel Marte , Nick Ahmed , Daniel Descalso


Toronto Blue Jays vs. Edwin Jackson

Before his last start in which he allowed five earned, Edwin Jackson had been fairly decent, at least that’s what the numbers say. He’s gotten a little lucky as his 3.86 ERA doesn’t exactly match with his mid-four xFIP and SIERA. He’s also allowing over 32-percent hard contact rate as well, so another check in the lucky column. Now he’s going to run into a Blue Jays offense that ranks 10th in wRC+ in all of baseball since July 1st versus right-handed pitching.

The Jays currently have six active players on their roster with wOBA’s of .345 or better against right-handed pitching this year. They are Justin Smoak , Curtis Granderson , Lourdes Gurriel Jr. , Randal Grichuk , Kendrys Morales and Dwight Smith Jr.  Granderson has a solid resume against Jackson going 5-for-15 with a homer. Smoak, Grichuk and Morales have all been hot lately hitting over .300 during their last 10 games while Grichuk has also flashed the power plus the average posting an OPS over 1.000. Gurriel might be the hottest hitter in the game notching 10 straight multi-hit games and hitting .500 over that span, but he left Sunday’s game with multiple injuries so it’s doubtful he plays here. Justin Smoak nearly hit 40 homers last year, so we know his upside. Aledmys Diaz is one last play I’m definitely willing to use here as he’s hit .355 with a .977 OPS over his last 10 including a homer on Sunday.

Primary Option(s): Randal Grichuk , Aledmys Diaz , Justin Smoak , Curtis Granderson

Secondary Option(s): Dwight Smith Jr. , Kendrys Morales
