Royals Notes: Lorenzen, Marsh, Harvey, McArthur

Michael Lorenzen will return from the 15-day injured list tomorrow. The Royals list him as the probable starter for the second game of their series in Washington. Kansas City will need to make a corresponding active roster move.

It’s a crucial start as K.C. fights for a playoff spot. The Royals squeaked out a 1-0 win in extra innings over the Nationals tonight. That kept them in front of the Tigers for the AL’s second Wild Card spot via the tiebreaker. They’re two games up on the Twins and 2.5 clear of the Mariners in the race.

Lorenzen has been down for more than a month because of a left hamstring strain. Acquired from the Rangers at the deadline, the righty had a sparkling 1.85 earned run average in 24 1/3 innings over his first five starts. That excellent run prevention was in spite of mediocre strikeout (17%) and walk (10%) rates. Lorenzen’s results have generally outpaced his peripherals for consecutive seasons. He carries a 3.43 ERA over 126 frames between Texas and K.C. this year.

Alec Marsh stepped back into the rotation while Lorenzen was on the shelf. He pitched fairly well, turning in a 4.50 ERA while striking out more than 32% of opponents over four starts. Marsh is moving into the bullpen to open a rotation spot, tweets Jaylon Thompson of the K.C. Star. The 26-year-old righty has turned in a 4.65 ERA with a solid 23% strikeout rate over 25 appearances (24 starts) on the year. He had an excellent start to the season before a terrible July led the Royals to option him to Triple-A for the three weeks preceding Lorenzen’s injury.

While Lorenzen’s return is a boost to the pitching staff, skipper Matt Quatraro provided disheartening updates on a pair of relievers this afternoon. The Royals have officially ruled out Hunter Harvey and James McArthur for the season, Quatraro said (X link via Anne Rogers of MLB.com). Harvey has been out since the middle of August with a back injury, while the Royals lost McArthur to an elbow sprain last week.

Quatraro said the Royals were sending Harvey for a second opinion, which at least raises the question of whether he’ll need surgery. Injuries have been a recurring problem for the 29-year-old righty. Harvey underwent Tommy John surgery as a prospect and has had extended absences during his MLB career for forearm, lat and elbow injuries.

Harvey can be a high-leverage reliever at his best, as he showed with the Nationals between 2023-24. He fired 60 2/3 innings of 2.82 ERA ball last season. This season’s 4.20 mark across 45 frames wasn’t as impressive, but Harvey punched out more than 26% of opponents behind a 13.4% swinging strike rate. The Royals viewed him as a late-game weapon and sent third base prospect Cayden Wallace plus the 39th pick in this summer’s draft to acquire him. They’ve gotten essentially nothing out of that deal, as Harvey allowed four runs over 5 2/3 innings before going on the shelf.

Kansas City controls Harvey for one more year via arbitration. The Royals would tender him a contract if they expect him to be back early in 2025, but a long-term injury could obviously change the calculus. He’d be due a small raise on this year’s $2.325MM sum.

McArthur operated as Kansas City’s closer for a time. He picked up 18 saves but also blew seven leads. McArthur’s heavy reliance on ground-balls without many whiffs plays better in the middle innings than it does in the ninth. His year concludes with a 4.92 ERA through 56 2/3 frames. The Royals are using deadline acquisition Lucas Erceg as their closer while turning high-leverage innings to converted starter Kris Bubic and left-hander Sam Long.
