Michael Wacha Bruce Kluckhohn-USA TODAY Sports

The Padres and free-agent righty Michael Wacha are in agreement on a contract, reports Ken Rosenthal of The Athletic (Twitter link). The CAA client’s deal is still pending the completion of a physical.

Wacha, 31, was the best remaining starting pitcher on the market and arguably the best free agent left standing overall. The right-hander turned in 127 1/3 innings of 3.32 ERA ball in 2022 — a fine rebound showing after a tough three-year stretch from 2019-21. Wacha’s 6% walk rate in 2022 was particularly sharp, and he scaled back his home run rate quite a bit in 2022 (1.83 HR/9 from 2019-21; 1.27 HR/9 in 2022). He was better than average at limiting hard contact from his opponents, surrendering an 88.2 mph average exit velocity and 35.4% hard-hit rate.

The 2022 performance, however, wasn’t without its red flags. A pair of trips to the injured list, one for an intercostal strain and another for shoulder inflammation, limited him to 23 starts. That shoulder issue was his fourth IL placement due to shoulder trouble since 2014. Wacha’s 20.2% strikeout rate and 41% ground-ball rate were below the league average, albeit by a matter of a couple percentage points each.

Ultimately, Wacha had a solid season but can’t reasonably be expected to replicate that shiny 3.32 ERA. Beyond the some of last year’s under-the-hood numbers, it should be pointed out that from 2019-21, Wacha pitched 285 1/3 innings with a 5.11 ERA between the Cardinals, Mets and Rays. Wacha’s strikeout, walk and ground-ball rates in that stretch all compare favorably to his 2022 work, however, and the main culprit for his struggles in that stretch could well have been an anomalously high home-run rate that trended back toward his career levels in 2022.

In all likelihood, Wacha’s true talent level lies somewhere between the extremes of that 2019-21 stretch and his sharp 2022 output. Fielding-independent marks pegged him around 4.00 last year (4.14 FIP, 3.99 xFIP, 4.07 SIERA). That’d make him a solid option closer to the back end of a big league rotation, which is just where he’s likely to slot in with his new club in San Diego. Joe Musgrove, Yu Darvish and Blake Snell are slotted into the top three rotation spots, but Wacha will give the Friars a solid No. 4 option.

Both Nick Martinez and Seth Lugo are expected to be utilized as starters with the Padres in 2023, but it’s not a given that Wacha will push either to the bullpen. There’s been talk of a six-man rotation in San Diego, which is only sensible given that Martinez and Lugo both worked primarily out of the bullpen in 2022. Martinez made 10 starts for the Padres but 37 relief appearances, finishing out the season at 106 1/3 innings. Lugo has been exclusively a reliever in 2021-22, with his last start coming for the 2020 Mets. Both righties will likely see their workloads monitored in 2023, so bringing Wacha into the mix both gives the Padres some sorely needed depth and gives them an organic mechanism with which to manage the innings counts for Martinez and Lugo.

Even looking beyond the possible six-man rotation, the Padres are now simply better positioned to withstand an injury to one of their top five arms. That’s of particular importance, as recent trades have thinned out the system’s depth. Gone are MacKenzie Gore, Chris Paddack, Luis Patino, Cal Quantrill and Robert Gasser, who were traded in the respective packages that netted Juan Soto, Taylor Rogers, Snell, Mike Clevinger (who departed as a free agent) and Josh Hader.

The top depth options behind Martinez and Lugo on the 40-man roster had been Adrian Morejon (57 1/3 innings in 2022), Ryan Weathers (6.73 ERA in Triple-A), Reiss Knehr (6.88 ERA in Triple-A), Pedro Avila (13 1/3 MLB innings) and Jay Groome (zero MLB experience; 67 innings Triple-A). Non-roster veterans in camp include Julio Teheran, Wilmer Font and Aaron Brooks. Suffice it to say, any serious injury to the starting staff pre-Wacha would’ve stretched the depth; two might have been disastrous. Wacha helps to lessen such risks.

While financial terms of the deal aren’t yet clear, the signing of Wacha could come with notable repercussions with regard to the luxury tax. San Diego is currently less than $7M away from the third tier of luxury penalization, which kicks in at $273M. If the Friars exceed that point, they’ll begin to be taxed at a 75% rate for any money spent up to $293M (rather than the 45% rate at which they were taxed on the previous $20M spent). That’s a small slap on the wrist by itself, but stepping into the third bracket of luxury penalties also pushes a team’s top pick in the next year’s draft (i.e. 2024) back by 10 places. The team’s league-allotted bonus pool is also inherently reduced, in conjunction with the diminished slot value of that pick.

The Padres are a team in all-out win-now mode, so perhaps owner Peter Seidler and president of baseball operations A.J. Preller simply determined that crossing that mark was a necessary evil in order to field the best team possible for the upcoming season. If that’s the case, further additions to the roster could yet be forthcoming. Alternatively, it’s always possible with the ever-active Preller that some type of trade will be orchestrated in order to slightly lower payroll and drop the team back under that $273M luxury mark.
