Projecting a Joe Musgrove Contract Extension

All-Star Week may be a relaxing midseason respite for most players, but for front offices, it’s business as usual. For the Padres, it may be a high-stakes one, as they’re reportedly closing in on a long-term deal with their best starting pitcher, Joe Musgrove. Without a deal, he hits free agency for the first time in his career, and there’s not much that teams like less than being drawn into a bidding war over their ace.
The starting pitchers the Padres have acquired over the last few years have mixed in many lows with their highs, but Musgrove has been rock-solid in mustard-and-brown, putting up a 2.90 ERA, a 3.48 FIP, and a hair under six WAR in 47 starts since coming over from the Pirates. During last season’s late-year debacle that saw San Diego in desperate enough straits to sign Jake Arrieta as a free agent and throw him into the rotation, Musgrove was a rare example of solidity, with only one truly awful start in the last month of the season. While he’s lost some strikeouts from 2021, he’s also bid adieu to some of the walks — not an unpleasant tradeoff, given that he ranks fifth among qualifying starters in lowest average exit velocity at 86.7 mph.
Fewer walks and strikeouts have allowed Musgrove to get through innings slightly more efficiently. As a result, he’s averaged almost a full inning per start more than last year while throwing just three more pitches per outing. Getting through the sixth more often has resulted in his quality start percentage shooting up from 48% to 88%; among MLB qualifiers, only Framber Valdez has racked up a higher rate. Musgrove’s five-inning loss to the Rockies last Wednesday was the first time he failed to finish six innings this season. This durability and consistency are crucial to the Padres, given their experience last season when they tried to keep the rotation’s inning count low in the early going, resulting in an exhausted bullpen breaking down by July.
With the trade deadline fast approaching, getting some certainty about Musgrove’s future with the club has quite a bit of value. The Padres seem likely to add a bat, and getting a better idea of how many pitchers they’ll need to replace over the next few years should provide some guidance on which prospects they can afford to give up. Sean Manaea and Mike Clevinger are also free agents after this season, and Blake Snell and Yu Darvish will be after 2023, so getting Musgrove inked for most of the rest of the decade takes at least one problem off their plate.
So, what kind of deal is Musgrove likely looking at? Let’s fire up ZiPS and run him through the mathematical wringer. Read the rest of this entry »
