At long last, Edwin Jackson can unpack -- we think. While his four-year, $52 million contract with the Cubs doesn't include a no-trade clause, Jackson should at least call Wrigley Field home for the next couple of years. Considering that the 29-year-old righty was on pace to obliterate Octavio Dotel's record for most teams played for in a career -- Jackson has been a Dodger, Devil Ray, Tiger, Diamondback, White Sock, Cardinal and National, and was technically a Blue Jay for a brief moment (though he never suited up) -- that's a step in the right direction.
It's surprising that it has taken Jackson this long to settle down in one city. He might not be the Cy Young contender that people envisioned when he celebrated his 20th birthday by outdueling Randy Johnson during his MLB debut, but Jackson has been above-average since he reached Detroit (106 ERA+ from 2009-12) while tossing slightly over 200 innings pitched per season. That combination of quality and quantity has made Jackson the 29th-most valuable starter over that time frame, judging by Baseball-Reference's Wins Above Replacement.
Jackson's slider is the main reason that he has evolved from a perceived bust to a solid starter making serious bank. Here's a closer look at his mid-to-high-80s breaker, which ranks among the game's best out pitches.
- Jackson threw his slider 29.3% of the time in 2012, the ninth-highest clip among MLB starters. Ryan Dempster (39.5%), Madison Bumgarner (35.6%), Bud Norris (36.3%), Ervin Santana (36.3%), Francisco Liriano (32.5%), Jason Marquis (32.1%), CC Sabathia (31.8%) and Bruce Chen (29.9%) were the only starters to rely on the slide-piece more often.
- With a miss rate approaching 50%, Jackson got swings and misses with his slider more frequently than any other starter in the game:

- Jackson uses his slider as a chase pitch, placing just 37.3% of them within the strike zone. The average for starters, by contrast, is about 47%. Hitters can't seem to lay off those off-the-plate-sliders. Check out Jackson's swing rate by pitch location with his slider, and then the league average for right-handed starting pitchers:

Jackson boasted the highest slider chase rate (44.1%) among NL starters last year. In the AL, only Colby Lewis (50.7% slider chase rate), Brian Matusz (48.3%), Yu Darvish (44.6%) and Liriano (44.6%) made batters hack at more would-be balls.
- Fanning 111 hitters with his out pitch, Jackson led NL starters in slider strikeouts and trailed just Sabathia (138 slider Ks) among all starters.
- While the slider is usually more effective against same-handed hitters, Jackson actually got better results with the pitch against lefties. He held left-handers to a .299 slugging percentage against his slider, compared to .361 against righties. For comparison's sake, righty starters surrendered a collective .386 slugging percentage with sliders against lefty batters last season, and a .350 slugging percentage against righties.
