STARTERS

1. Patrick Corbin, LHP, Nationals*

Dec. 4: Corbin signed 6-year, $140M contract with Nationals

At 23, Corbin seemed poised to be an ace in waiting. That was before he lost the entire 2014 season to Tommy John surgery. At 28, he bounced back and returned to dominance. He made his second All-Star team, threw 200 innings for the second time in his career, and will almost certainly finish third behind Jacob deGrom and Max Scherzer for the National League Cy Young award. At 29, expect him to decline a qualifying offer from the Diamondbacks, but draft-pick compensation won't scare suitors away.

2. Dallas Keuchel, LHP (31)

W-L ERA IP SO WHIP WAR
12-11 3.74 204.2 153 1.31 3.6

Keuchel's 2018 ERA is somewhat alarming, but it's worth noting that he was limited to only 145 2/3 innings the season prior due to neck issues. It's encouraging that he was able to reach 200 innings for the first time since 2015. A pitch-to-contact hurler, he'll always give up his fair share of hits, but another expected step forward after his recovery makes the former Cy Young winner the second-best option on the list.

3. Charlie Morton, RHP, Rays*

Dec. 12: Morton signed 2-year, $30M contract with Rays

Morton has re-written his career arc since signing with the Astros, posting a 10.4 K/9 with a combined 3.36 ERA in his two seasons in Houston. However, durability issues make him a risk. His career high of 171 2/3 innings in 2011 may be out of reach, but if he's willing to keep playing, he'll be a solid mid-rotation arm into his mid-to-late 30s.

4. Nathan Eovaldi, RHP, Red Sox*

Dec 6: Eovaldi signed 4-year, $68M contract with Red Sox

A reliable hand during the regular season, Eovaldi turned into a superhuman in the postseason. He posted a 1.61 ERA across 22 1/3 innings over three playoff series, including a gritty six-inning relief outing in Game 3 of the World Series. He isn't eligible to receive a qualifying offer since he was traded from Tampa midseason, so a supplemental draft pick won't be attached to his signing.

5. Hyun-Jin Ryu, LHP, Dodgers*

Nov 12: Ryu accepted 1-year, $17.9M qualifying offer from Dodgers

Ryu may be the poster child for a crop of free-agent starters largely marked by questionable health and durability. Back and shoulder problems ended his 2015 campaign before they even started, while an elbow issue limited him to one appearance in 2016. He's been reliable when healthy, especially this past season, but he failed to reach 100 innings in 2018. His ceiling remains high, but he's not without risk.

6. J.A. Happ, LHP, Yankees*

Nov 12: Happ signed 2-year, $34M contract with Yankees

Improbable as it may seem, Happ's trip to the 2018 All-Star Game at age 35 was his first such appearance. The lefty was the Blue Jays' most consistent pitcher for parts of three seasons before he anchored the Yankees' rotation down the stretch this past summer. He went 7-0 with a 2.69 ERA over 63 2/3 innings in 11 starts after being traded to the Bronx. The only knock against him is his age, which may be overblown.

7. Gio Gonzalez, LHP

W-L ERA IP SO WHIP WAR
10-11 4.21 171 148 1.44 2.0

Gonzalez has pitched at least 158 innings in every season since 2010, often touching the 200-inning plateau. While he won't dazzle with top-notch stuff, the veteran lefty has shown he can hold his own as a durable mid-rotation starter. He rebounded from an uneven start to the season once he was traded to the Brewers for the home stretch.

8. Matt Harvey, RHP, Angels*

Dec. 18: Harvey signed 1-year, $11M contract with Angels

The Dark Knight's tumultuous last few seasons have obscured just how incredible he was to start his career; hopes that he can rekindle that fire will earn him ample interest. Harvey did make 28 starts between the Mets and Reds in 2018 - his most since 2015 - and he improved in every statistical category after his trade from New York to Cincinnati.

9. Lance Lynn, RHP, Rangers*

Dec. 12: Lynn signed 3-year, $30M contract with Rangers

Lynn had a disastrous start to his 2018 campaign, posting an 8.37 ERA through the end of April. A rough July (6.08 ERA) ballooned his stats the rest of the way, but a 3.34 FIP showed he was the victim of some rotten luck. He's now two seasons removed from a lost 2016 to Tommy John, and could be a stealth innings-eater like he was during most of his tenure with the Cardinals.

10. Ervin Santana, RHP, White Sox*

Feb. 22: Santana reportedly signed minor-league contract with White Sox

Santana barely pitched last season thanks to finger surgery, and now hits free agency after having his option declined by the Twins. He made 33 starts and went 16-8 with a 3.28 ERA over 211 1/3 innings in 2017, marking the sixth time in 14 seasons that he's thrown at least 200 innings. He's getting a little long in the tooth, but he could still round out a rotation if his finger issues are behind him.

RELIEVERS

1. Craig Kimbrel, RHP

ERA IP SO WHIP FIP SV
2.74 62.1 96 0.99 3.13 42

Kimbrel is bound to receive a qualifying offer from the Red Sox, which he'll almost surely decline. As good as he is, the seven-time All-Star wasn't without his warts in 2018. He walked 4.48 batters per nine innings, up from 1.83 in 2017, and had a career-worst 1.01 HR/9. He also posted a 5.91 ERA in 10 2/3 innings during the postseason. Still, since 2013, no one has recorded more saves than Kimbrel's 244.

2. Adam Ottavino, RHP, Yankees*

Jan 17: Ottavino signed 3-year, $27M contract with Yankees

While he doesn't fit the "proven closer" mold, Ottavino possesses the nastiest slider in the game. His propensity to issue walks is concerning, but he compensates for that by allowing hits at a low rate. He was the Rockies' best reliever by a wide margin and was worth more wins above replacement (2.0) than any other free-agent relief pitcher in 2018.

3. Zach Britton, LHP, Yankees*

Jan. 5: Britton signed 3-year, $39M contract with Yankees

That Britton stayed on the field this year after returning from a ruptured Achilles is a great sign for potential suitors, even if he wasn't the version of himself who converted 120 saves with a 1.38 ERA over 209 innings from 2014 through 2016. At his best, he limits damage in a variety of ways by almost never allowing home runs and striking out around a batter per inning.

4. David Robertson, RHP, Phillies*

Jan. 3: Robertson signed 2-year, $23M contract with Phillies

Robertson had a typically productive season out of the Yankees' bullpen. You can pretty much set your watch to him throwing at least 60 innings each year while posting a quality ERA. He has the most reliable floor of the available relievers.

5. Andrew Miller, LHP, Cardinals*

Dec. 21: Miller signed 2-year, $25M contract with Cardinals

Miller was the most dominant reliever in baseball from 2014 to 2017, posting a 1.72 ERA with 421 strikeouts in 261 innings (14.5 K/9). He's only a season removed from making the AL All-Star team, but his injury-plagued 2018 will temper expectations as he nears his mid-30s. A return to form is hardly guaranteed.

6. Jeurys Familia, RHP, Mets*

Nov 13: Familia signed 3-year, $30M contract with Mets

Familia put together an all-around impressive campaign between the Mets and Athletics, and was used primarily as a setup man in Oakland in front of Blake Treinen. He'll seek a big contract and will likely settle in as a team's ninth-inning option to open 2019.

7. Kelvin Herrera, RHP, White Sox*

Rob Carr / Getty Images Sport / Getty

Jan. 7: Herrera signed 2-year, $18M contract with White Sox

Nothing went right for Herrera after he was traded from the Royals to the Nationals in June. He posted a 4.34 ERA in 18 2/3 innings after the deal - compared to a 1.05 mark with Kansas City - and suffered a season-ending foot injury in late August. It was the right-hander's first stay on the disabled list in seven seasons as a full-time major leaguer.

8. Brad Brach, RHP, Cubs*

Jan. 24: Brach reportedly signed 1-year, $3M contract with Cubs

Brach returned to form as a premier middle reliever after a midseason trade to the Braves. He posted a 1.52 ERA with 22 strikeouts over 23 2/3 innings with Atlanta down the stretch. It was a welcome sight after he posted uncharacteristically miserable numbers with the Orioles at the start of last season.

9. Cody Allen, RHP, Angels*

Hannah Foslien / Getty Images Sport / Getty

Jan. 17: Allen signed 1-year, $8.5M contract with Angels

Allen's rough season proved to be emblematic for an Indians squad that saw its bullpen, one of its greatest strengths the previous two years, become its biggest problem. He posted his worst ERA, walk rate, and HR/9 since becoming a fixture in Cleveland's relief corps in 2013. Despite all that, Allen had the third-best win probability added among free agent relievers at 2.01, trailing only Kimbrel and Ottavino. He's also never been bitten by the injury bug, totaling between 67 and 70 1/3 innings in each of the last six seasons. The question is whether or not he's burned out due to overuse.

10. Joe Kelly, RHP, Dodgers*

Kim Klement / USA TODAY Sports

Dec. 13: Kelly signed 3-year, $25M contract with Dodgers

A solid postseason where Kelly allowed only one run over 11 1/3 innings doesn't erase an uneven regular season. He did hurl 65 2/3 innings, though, which is his most since becoming a reliever in 2016.
