It's no secret the A's could use some starting pitching help.
The problem became more dire this week when the team announced talented left-hander Jesús Luzardo would be shut down for four to six weeks with a rotator cuff strain.
Though the season is already underway, there are still several starting pitchers available on the free agent market. Former Cy Young Award winner Dallas Keuchel tops the list, but don't expect the A's to throw massive money his way.
Instead, Oakland may choose to pursue one of these five starters:
Jackson certainly makes the most sense of anyone. The 35-year-old right-hander was the most pleasant of surprises last season. Jackson went 6-3 with a 3.33 ERA in 17 starts and was a key part of the A's clubhouse chemistry.
The two sides have been in contact for much of the offseason but have not been able to come to terms on a deal. That could change now that Jackson and the A's both figure to be a little more desperate.
At the age of 37, Shields is obviously nearing the end of his career, but he figures to get a shot somewhere in the league. The former All-Star went just 7-16 with a 4.53 ERA last season with the White Sox but did pitch over 200 innings.
Shields has a career ERA of 4.01 in 13 seasons. The right-hander would likely fair better on a team like Oakland, especially playing his home games at the pitcher-friendly Coliseum.
González is coming off season-ending rotator cuff surgery, but at just 34 years old he has a chance to bounce back. The right-hander went 8-13 with a 4.62 ERA in 2017, his last full season, but recorded a solid 3.73 ERA the year before.
González has a career ERA of 4.06 in seven major league seasons and could be another pitcher who would benefit from the Coliseum. He will be available for cheap, making him a low-risk signing.
Gallardo has struggled the past few seasons, but at just 33 years old, he still has time to regain his form. The right-hander has a career ERA of 4.06 in 12 big league seasons.
Gallardo's last productive season came in 2015 with the Texas Rangers. The former All-Star finished that year 13-11 with a 3.42 ERA. Like González, he should be available for a low cost.

Yes, Big Sexy is still going strong at the age of 45. You've got to think someone will take a flier on the former Cy Young Award winner, who will be entering his 22nd major league season.
Colón has 247 career wins and a 4.12 ERA, though he struggled to a 5.78 ERA last season in Texas. But three years ago, the right-hander went 15-8 with a 3.43 ERA and made his fourth career All-Star Game.
