2021 Fantasy Outlook
Perez found some mild success with Boston in 2020, posting a 4.50 ERA and 1.34 WHIP over 62 innings across 12 starts. However, his 5.20 xFIP suggests that he may have been somewhat lucky, and he also had a career-worst 38.5 GB% and 10.7 BB% during the 60-game season. Perez has leaned more on his off-speed pitches in recent years, while his average fastball velocity dropped to 92.1 mph in 2020. He had a career-high 18.3 K% over the past two years, but that mark is still below average. The southpaw had a career-worst 5.43 SIERA last year, and his hard-hit rate has been above 30% in each of the past five seasons. The 29-year-old could land a role as a back-end starter or swingman in 2021, but he's an unreliable fantasy option due to his struggles to limit meaningful contact recently. Even if he can land a spot in a starting rotation, Perez's inconsistent production makes him a risky season-long fantasy option. Read Past Outlooks

Back with Boston
Perez signed a one-year deal with the Red Sox on Saturday, Chris Cotillo of The Springfield Republican reports.
ANALYSIS
The Red Sox had previously declined a $6.25 million club option for the lefty. His new deal will be worth $4.5 million, with a $6 million club option and a $500,000 buyout for 2022, so Boston will wind up saving a small amount of money while still getting to bring Perez back. The 29-year-old looked like a legitimate rotation piece last season but not a particularly good one, as his 4.50 ERA in 12 starts came with an unimpressive combination of a 17.6 percent strikeout rate and 10.7 percent walk rate.

Perez was a surprise winner of a spot in Minnesota's rotation. Working with new pitching coach Wes Johnson, Perez developed a cutter and improved his delivery to add more velocity. He averaged 94.2 mph on his four-seamer and threw his cutter 30.8 percent of the time. The results were initially promising, as he had a 2.17 ERA, 1.15 WHIP and 8.0 K.9 in his first eight starts. However, the league appeared to figure out his new approach, as he had a 6.29 ERA and 6.6 K/9 over his last 21 starts. He struggled with the long ball in the second half, giving up 16 home runs in 14 starts. Perez held lefty batters to just a .585 OPS, but righties put up an .836 OPS against him. Boston signed him to a one-year, $6 million deal with a club option for 2021, and he projects to be the fifth starter. He should be a solid streamer against teams like the Orioles but could get a quick hook against the better AL lineups.
