Don’t look now, but the MLB regular season will be more than three-fourths over for nearly all the teams by the end of the week.

While some are still fighting for playoff positioning, there are others that are thinking how their starting pitching let them down this season.

In the offseason, teams will have a multitude of free agents to try to sign who can help bolster their starting rotation. Here are the top-ten free agent starting pitchers this offseason. Ages listed are how old they will be when the 2019 season begins. All stats are through games played on August 13.

(Note: Those who have club options or early opt-out options for next year are not included in the list. The notable starting pitchers with these are listed at the end of the article.)

10. Hyun-Jin Ryu - Los Angeles Dodgers

  • Age: 32
  • 2018 stats: 3-0 record, 2.12 ERA, 6 G (6 GS), 36 K, 29.2 IP, 0.88 WHIP
  • Career stats (5 seasons): 36-25 record, 3.33 ERA, 88 G (87 GS), 449 K, 505.0 IP, 1.23 WHIP

Ryu has been a very reliable pitcher for the Dodgers when healthy. Unfortunately, that hasn’t been the case that often recently. He has been out since May 2 with a groin strain and started just one game in 2016. Sporting News reports that he is expected to come off the disabled list on Wednesday.

9. Marco Estrada - Toronto Blue Jays

  • Age: 35
  • 2018 stats: 5-9 record, 4.84 ERA, 20 G (20 GS), 80 K, 106.0 IP, 1.28 WHIP
  • Career stats (11 seasons): 60-61 record, 4.12 ERA, 270 G (181 GS), 1,060 K, 1,190 IP, 1.19 WHIP

In 53 starts over the past two seasons, Estrada owns a 4.93 ERA. Still, a team will pay hoping to see once again the pitcher who led the AL in hits allowed per nine innings in both 2015 and 2016.

8. CC Sabathia - New York Yankees

  • Age: 38
  • 2018 stats: 7-4 record, 3.32 ERA, 22 G (22 GS), 106 K, 119.1 IP, 1.28 WHIP
  • Career stats (18 seasons): 244-150 record, 3.69 ERA, 531 G (531 GS), 2,952 K, 3,436.1 IP, 1.25 WHIP

Many considered Sabathia finished as he struggled from 2014-16 to the tune of a 4.81 ERA in 69 starts. His ERA has dropped each of the last five seasons though, and his current 3.22 would be his best since 2011.

According to NBC Sports, Sabathia was placed on the disabled list on Monday with right knee inflammation.

7. Lance Lynn - New York Yankees

  • Age: 31
  • 2018 stats: 8-8 record, 4.46 ERA, 23 G (22 GS), 122 K, 119.0 IP, 1.54 WHIP
  • Career stats (7 seasons): 80-55 record, 3.50 ERA, 206 G (183 GS), 1,041 K, 1,096.2 IP, 1.31 WHIP

Lynn looked awful at times in his first year with the Twins, but he has looked revitalized since he was traded to the Yankees. Before this season, he never had an ERA over four in his six years with the Cardinals.

6. J.A. Happ - New York Yankees

  • Age: 36
  • 2018 stats: 12-6 record, 4.07 ERA, 22 G (22 GS), 141 K, 126.0 IP, 1.13 WHIP
  • Career stats (12 seasons): 104-82 record, 3.94 ERA, 275 G (250 GS), 1,305 K, 1,479.0 IP, 1.32 WHIP

Happ was named an All-Star for the first time this year and was a 20-game winner for the Blue Jays in 2016.

He is on pace to have his highest strikeout rate and lowest WHIP of his career.

5. Gio Gonzalez - Washington Nationals

  • Age: 33
  • 2018 stats: 7-8 record, 3.89 ERA, 23 G (23 GS), 111 K, 125.0 IP, 1.48 WHIP
  • Career stats (11 seasons): 124-94 record, 3.65 ERA, 304 G (298 GS), 1,711 K, 1,768.0 IP, 1.32 WHIP

Gonzalez is one season removed from a sixth-place finish in NL Cy Young voting. While his numbers aren’t quite as impressive in 2018, his ERA is once again under four. Other than 2016, that has been the case every year since 2010.

4. Nathan Eovaldi - Boston Red Sox

  • Age: 29
  • 2018 stats: 5-4 record, 3.74 ERA, 13 G (13 GS), 62 K, 74.2 IP, 1.02 WHIP
  • Career stats (7 seasons): 43-50 record, 4.17 ERA, 147 G (140 GS), 601 K, 813.2 IP, 1.35 WHIP

Eovaldi has thrown a couple of clunkers this season but otherwise has looked dominant at times for the Rays and Red Sox.

In his first two starts after being traded to Boston, he threw 15 scoreless innings and allowed just seven hits. After having some control issues to begin his career, he is only walking 1.7 hitters per nine innings thus far on the year.

3. Charlie Morton - Houston Astros

  • Age: 35
  • 2018 stats: 12-3 record, 2.88 ERA, 23 G (23 GS), 171 K, 135.1 IP, 1.15 WHIP
  • Career stats (11 seasons): 72-81 record, 4.23 ERA, 210 G (209 GS), 964 K, 1,177.0 IP, 1.38 WHIP

Like Happ, Morton was a first-time All-Star in 2018. He is on pace for career-highs and bests in nearly every category. He currently sits sixth in the AL in strikeouts and seventh in ERA.

2. Patrick Corbin - Arizona Diamondbacks

  • Age: 29
  • 2018 stats: 9-4 record, 3.15 ERA, 24 G (24 GS), 183 K, 148.2 IP, 1.04 WHIP
  • Career stats (6 years): 54-51 record, 3.95 ERA, 163 G (145 GS), 834 K, 894.1 IP, 1.30 WHIP

Corbin is in the midst of a career year which he should be able to parlay into a rather large contract in the offseason.

He ranks third in the NL in strikeouts, fourth in the WHIP, and eighth in ERA. The reason why is he isn’t first on the list is because he hasn’t consistently put up seasons similar to this in his career.

1. Dallas Keuchel - Houston Astros

  • Age: 31
  • 2018 stats: 9-9 record, 3.43 ERA, 25 G (25 GS), 115 K, 155.0 IP, 1.24 WHIP
  • Career stats (7 seasons): 73-61 record, 3.62 ERA, 183 G (174 GS), 907 K, 1,139.2 IP, 1.24 WHIP

The 2015 AL Cy Young winner, Keuchel ended with an ERA under three in three of the last four years entering 2018. While it’s above that mark this season, he still has earned 16 quality starts out of his 25 appearances. Since June 16, his ERA is 2.19 in 70 innings.

Notable club options: Madison Bumgarner ($12 million), Carlos Carrasco ($9 million), Cole Hamels ($20 million), Chris Sale ($15 million), Ervin Santana ($14 million)

Notable early opt-out options: Clayton Kershaw (can opt-out with two years, $65 million remaining), David Price (can opt-out with four years, $127 million remaining)
