2020 Fantasy Outlook
Gonzales illustrates pitching volatility. His ERAs the past two seasons are nearly identical: 4.00 in 2018 and 3.99 last season. The thing is, he was a significantly better pitcher two years ago but was unlucky. In 2019, the luck happened to reverse. To wit, Gonzales' 2018 xFIP was 3.59 with a 3.81 SIERA. Last year they were 5.11 and 5.08, respectively. Driving the difference was a drop in strikeouts combined with poorer control along with an uptick in HR/9. His 2019 K-BB% was 10.5%, down six points from the prior campaign. While variance affects all hurlers, it tends to manifest more on those with low strikeout rates and Gonzales' 17% mark was well below average. Now over three years removed from Tommy John surgery, Gonzales is durable, the prototypical innings eater. His volatility is a mixed-league risk, but his better skills at home render the southpaw an option in leagues conducive to streaming. Read Past Outlooks

Signs four-year extension
PSeattle Mariners
February 3, 2020
Gonzales signed a four-year extension with the Mariners on Monday.
ANALYSIS
The deal contains a club option for a fifth season, giving Seattle control over the lefty through his age-32 season and buying out up to two years of his free agency. Gonzales will make $30 million over the first four years of the deal, Ken Rosenthal of The Athletic reports. The southpaw has emerged as the rebuilding Mariners' top starter over the last two seasons, posting ERAs of 4.00 and 3.99. His 18.7 percent career strikeout rate keeps his fantasy ceiling fairly low, however.

2014
Gonzales enjoyed a bounce-back season with Seattle thanks in part to a new cutter that gave him another weapon to attack righties. Righties crushed him in St. Louis in 2017 to the tune of .346/.388/.566, so Gonzales added a cutter and that slash line improved to .266/.309/.418 last season. His 4.00 ERA feels out of place for a pitcher with a 1.22 WHIP and a 16.5 K-BB%. Gonzales does not have another level when it comes to strikeouts, but the improving walk rate is encouraging for him since he averages more than a hit allowed per inning. As long as he can limit his walks, the extra hits get offset. The innings spike looks greater than it was -- Gonzales logged 126.1 innings between the minors and majors in 2017 in his first season back from Tommy John surgery. There is some concern for a letdown in 2019, but Gonzales has job security and a favorable home park, so he's at least in the mix as a streamer.
Gonzales returned from Tommy John surgery last season, making 11 appearances (eight starts) with the Mariners after coming over from St. Louis in a July trade. The results were ugly, but the top estimators point to the lefty being at least a run better than his ERA would suggest (5.06 FIP, 4.46 xFIP, 4.48 SIERA). His strikeout rate was modest at 7.2 K/9 and Gonzales had trouble with the long ball (1.80 HR/9), but he posted a strong walk rate for the year (2.5 BB/9) and his numbers at Triple-A were solid. Gonzales was excellent in seven relief innings (24.1 K-BB percentage) and he finished strong overall, posting a 2.81 ERA in September. As things stand, Gonzales appears likely to serve as Seattle's swingman to open 2018. That puts him just an injury away from starts, and of course the top two arms in the Mariners' rotation (James Paxton and Felix Hernandez) have dealt with a slew of injuries in recent years.
After missing 2016 due to Tommy John surgery, Gonzales is unlikely to be back pitching in games until a month or two into the 2017 season. He will almost certainly spend time at Triple-A Memphis once healthy due to the fact that he is yet to impress in the majors and seemed to take a step back in the minors before he went under the knife. Over 14 starts with Memphis in 2015 (when he most recently pitched), Gonzales really struggled to retire the opposition, as batters hit .317 with him on the mound. He was much better at Triple-A in 2014, and it is possible his elbow was already an issue during his struggles in 2015. His stuff profiles better at the back of a big league rotation than in the bullpen, so he should continue to be developed as a starter, but given the Cardinals' rotation depth it is unclear when he will get a legitimate look in that role as long as he remains in this organization.
Gonzales’ proximity to the big leagues is the selling point and his lack of upside is a reason to look elsewhere in dynasty leagues. He will never be more than a No. 3 starter, and of course he’s far from a lock to actualize that ceiling. Assuming Carlos Martinez is over the shoulder issues that plagued him at the end of the year, Gonzales, Tim Cooney and Tyler Lyons are all on the outside looking in on the rotation heading into spring training. Gonzales had his own shoulder issues in the first half of last season, which may have contributed to his shaky run in the Pacific Coast League, but he will nonetheless be relying more on stuff and reputation than tangible success. Meanwhile, Cooney and Lyons can both point to successful, albeit brief runs in the MLB rotation last season, so Gonzales should enter camp as an underdog to serve as the first choice to fill in if someone in the rotation goes down with an injury.
Gonzales was terrific for the Cardinals when called upon in 2014, posting a 4.12 ERA in seven starts and striking out 39 in 43.2 innings. His xFIP of 2.94 shows just how good he was and going into his age-23 season, there's a lot for Cardinals fans and fantasy owners to be excited about. Arguably the organization's top pitching prospect entering 2014, Gonzales has a legitimate shot to crack the Cardinals' rotation in 2015 following the departure of Shelby Miller. He'll have to beat out fellow phenom Carlos Martinez along with oft-injured Jaime Garcia. Gonzales clearly has the talent to do so and if he gets the chance, he could be a great fantasy asset. However, the Cardinals could choose to develop Gonzales the same way they have Martinez, who was relegated to bullpen duties despite arguably being St. Louis' best pitcher last spring.
Gonzales was the Cardinals' first-round pick out of Gonzaga University in the 2013 draft. The lefty is a high-floor pitcher, but he doesn't have a ton of upside and could work his way to the majors late this season. In his first season as a professional, Gonzales posted a 2.70 ERA in 23.1 innings, striking out 23 while walking eight. It's an extremely small sample size, and the Cardinals will have a much better idea of what they have in the 22-year-old after a few months in Double-A, where he should start the 2014 season.
