Pablo Lopez Changing It Up

What Happened in 2020?

On the season, Pablo Lopez ended with a 3.61 ERA, 1.19 WHIP, and 59 strikeouts in 57.1 innings. Through 11 starts, Lopez logged four quality starts and allowed two or fewer runs in nine out of 11 games started. His 9.26 K/9 increased from 7.68 K/9 through 111.1 innings in 2019, while his 2.83 BB/9 slightly increased from 2.18 BB/9 in 2019. On the surface, another notable difference in 2020 includes the lowered ratios down from a 5.09 ERA and 1.24 WHIP in 2019. Lopez’s 0.63 HR/9 also dropped from 1.21 HR/9 in 2019, so several contributing factors led to a more successful season with Pablo Lopez changing it up.

Batted Ball Profile & Plate Discipline

When glancing at his batted ball profile, Lopez traded a lowered 28.6% fly-ball rate for an increased 52.2% ground ball rate. His line drive and fly ball rate dropped 2-3% while his ground ball rate increased by about 4.5%. I mentioned the lowered HR/9, and his 8.7% HR/FB rate also dropped from a 14.6% HR/FB in 2019. One of the reasons for a lower 2020 ERA involves the drop in home run rate.

A few notable changes in plate discipline involve a reduced contact rate and zone contact rate while the swing rate increased slightly across the board. As expected, Lopez’s 12.1% swinging-strike rate increased from 10.2% in 2019, with a higher strikeout rate this season. Below we’ll note the changes in contact rate and swing rate.

Plate Discipline

Overall, we notice hitters made less contact overall and inside the zone while hitters made slightly more contact outside the zone. His O-Swing% and Z-Swing% also increased, and maybe that contributed to the increased strikeout rate as well. Lopez also increased his first-pitch strike rate and tossed fewer pitches inside the zone. Overall, take this data with a grain of salt since he pitched a career-high 111.1 innings in 2019 compared to 57.1 innings in 2020.

Pablo Lopez Changing It Up – Pitch Mix

With Pablo Lopez changing it up, let’s look at his pitch mix. Lopez used a mixture of five pitches with the four-seam fastball, changeup, and sinker as the top three options. He utilized his cutter (8.4%) and curveball (7%) less often. The most notable change, hence the title “Pablo Lopez Changing it Up,” involves the increased changeup usage.

Pitch Usage

When looking at the pitch mix usage, Lopez lowered his four-seam fastball usage and increased the changeup usage since that’s his best pitch. With the decrease in four-seam fastball usage, the results on his four-seamers also improved in terms of whiff percentage, xBA, xSLG, and xwOBA compared to 2019. In doing so, that contributed to the improved strikeout rate and ERA for Lopez. With that, let’s look at the filthy changeup. 

Results on Pablo Lopez’s Changeup

Lopez increased the changeup usage from 22% in 2019 to 29.9% in 2020, and thus the improved results across the board. His swinging-strike rate and whiff rate also increased while the batting average, slugging percentage, and wOBA allowed dropped. The increased swings and misses paired with the lowered home run rates again contributed to the improved ratios and strikeout rate.

Pablo Lopez Rolling Expected wOBA

The visual above showed the lowered expected wOBA in 2020 compared to 2019, which made sense considering the improved ratios and results across the board. Again, since Lopez used his best pitch (changeup) more often, he displayed better results. Hopefully, we continue to see Pablo Lopez changing it up.

Plate Discipline Changes by Pitch

A few other notable changes include the plate discipline by pitch. Lopez’s four-seam fastball, changeup, and sinker all resulted in a lowered zone contact rate in 2020 compared to 2019. Furthermore, the zone swing rate increased on the four-seamers and sinkers. His four-seamers had a 63.9% Z-Swing% in 2019 and 70.3% in 2020. Meanwhile, the sinkers had a 62.7% Z-Swing% in 2019 and 74.4% in 2020. The swinging-strike rate on his four-seamers increased from 7.9% in 2019 to 13.8% in 2020, and also contributed to the increased strikeout rate.

Statcast Data

Pablo Lopez 2020 Statcast Data

Overall, Pablo Lopez’s Statcast data looked interestingly consistent over the past three seasons. In 2020, he allowed an 85.7 mph average exit velocity (90th percentile), 32.3% hard-hit rate (79th percentile), and a .270 xwOBA (79th percentile). Since he consistently allowed a similar quality of contact and his Statcast gradually improved, it’s another positive attribute for Lopez. In 2018 and 2020, Lopez allowed an average exit velocity that ranked in the top 10% of the league. The table below displays the improvements in his Statcast data across the board.

2021 Outlook – Pablo Lopez Changing It Up

Pablo Lopez was a value in drafts with his 371.42 NFBC ADP with a high pick of 196 and a low pick of 483. We expect his ADP to rise in 2021 fantasy baseball drafts with Pablo Lopez changing it up and increasing his changeup usage. However, Lopez should be a draft value in 2021 since he tends to fly under the radar.

Hopefully, we see Pablo Lopez changing it up and utilizing his best pitch more often in 2021. Amongst starting pitchers that threw at least 50 innings in 2020, Pablo Lopez ranks 15th with a 3.09 FIP in between Sonny Gray, Dallas Keuchel, Kevin Gausman, and Max Fried. Lopez likely falls closer to Keuchel and Gausman than Gray and Fried, but still good company and a starting pitcher in the later rounds to target in 2021 redraft leagues. Check out where Fantrax writer Jake Devereaux ranked Pablo Lopez in his top-100 starting pitcher rankings for 2021.
