MLB Underdog Fantasy Top Picks September 12

Julio Rodriguez, Seattle Mariners – HIGHER than 0.5 Runs Scored

Following last night’s four-hit outburst for Rodriguez, he now has three straight multi-hit efforts, and his hitting a cool .500 over his last four games with three home runs, six runs scored, and four RBI. Rodriguez is 3-for-8 with two home runs in his career against Los Angeles’ left-hander Patrick Sandoval, and you will be hard-pressed to find a better hitter against southpaws right now than Rodriguez. Sure, he’s slashing .328/.363/.516 against them this year with an .879 OPS and .373 wOBA. However, the real magic has happened of late. Since August 1, Rodriguez is 17-for-30 (.567 AVG) with three doubles, two home runs, six runs scored, and 11 RBI against left-handed pitching! That’s good for a .933 SLG, 1.527 OPS, .367 ISO, .635 wOBA, and 323 wRC+!

Bryan Woo, Seattle Mariners – LOWER than 5.5 Strikeouts

Woo was a quality strikeout arm early in his big league tenure. Through his first nine starts (44 IP), he posted an 11.05 K/9 and 28.9 percent strikeout rate. However, those numbers have quickly faded, and he’s had opponents that he should have been able to take advantage of, but just hasn’t for the most part. Over his last five starts, he has a 4.85 K/9 and 13 percent strikeout rate. He has faced the Angels twice this year, and put up six or more strikeouts in each outing, but he really struggles with left-handed hitters, and the Angels are going to run quite a few left-handed bats out there. Woo’s velocity has dipped a bit the past couple of outings, and they haven’t let him throw more than 85 pitches in a start since July 23, which shouldn’t come as all that much of a surprise, seeing as he threw 57 innings in 2022, and now in 2023 he has 44 innings at Double-A and 70 innings in the majors. That’s quite a jump, so he could be just losing some steam. While he’s had some success against the Angels this year, I don’t envision him putting up the strikeout numbers he has in past outings.

Juan Soto, San Diego Padres – HIGHER than 1.5 Hits+Runs+RBI

Soto broke out of a mini-slump in a big way last night, recording three hits (1 HR) with four RBI and two runs scored. Is he in store for another big day? I think so! Los Angeles starter Lance Lynn has allowed a .309 batting average and .587 SLG this year to left-handed hitters, and after a hot start with the team, he’s coughed up 15 runs over his last nine innings of work, including a combined six home runs to the Braves and Marlins. Soto has a .256 ISO and .930 OPS against right-handed pitching this season, and he’s actually been better away from his home park this year, slashing .298/.415/.573 with a .275 ISO on the road in 2023.
