Read on for my MLB picks for Friday, September 12.

Rays vs Cubs prediction

Rays vs Cubs best bet: Under 7.5 (-120)

The Chicago Cubs hand the ball to left-hander Matthew Boyd, who looks to cement the best season of his professional career. Through 28 starts, Boyd is 12-8 with a 2.92 ERA and 1.06 WHIP.

His underlying metrics are equally impressive. Entering this matchup, Boyd ranks in the top half of the league in xERA, xBA, average exit velocity and hard-hit rate.

This success is likely to continue against the Tampa Bay Rays, a team Boyd has a 3.32 ERA and 0.89 WHIP against over the past three meetings.

Meanwhile, right-hander Shane Baz takes the mound for Tampa. He also ranks in the top half of the league in xERA, xBA, average exit velocity and hard-hit rate.

Both bullpens are capable of closing the deal in this contest. This season, both relief corps rank in the top half of the league in ERA, xERA, FIP and xFIP.

Rays vs Cubs same-game parlay (SGP)

Baz particularly thrives in generating swings and misses. This season, he ranks in the top half of the league in chase rate, whiff rate, and strikeout rate.

On the other hand, Boyd has recorded six or more strikeouts in each of his past three starts against Tampa.
