Luis Medina Diagnosed With Grade 2 MCL Sprain

Athletics righty Luis Medina will begin the season on the injured list after being diagnosed with a Grade 2 sprain of the medial collateral ligament in his right knee, manager Mark Kotsay announced this morning (X link via Martin Gallegos of MLB.com). Medina exited his most recent spring start with a knee sprain of unknown severity and was seen in the A’s clubhouse on crutches this morning. There’s no firm timetable for Medina’s return to the Oakland roster, but a Grade 2 sprain likely comes with an absence of some note.

Acquired alongside JP Sears and Ken Waldichuk in the trade that sent Frankie Montas and Lou Trivino from the A’s to the Yankees, Medina may have had the inside track on the Athletics’ fifth starter job this spring. Sears, Paul Blackburn and offseason pickups Alex Wood and Ross Stripling are locked into the top four spots, but Medina had more success in the majors than the remainder of the (non-Sears) pitchers the A’s have landed over the course of their current rebuild.

Looking strictly at last year’s 5.42 ERA in 109 2/3 innings, that might not seem to be the case, but Medina was shelled early in his debut campaign before finishing the year on a more solid stretch. Over his final 11 starts and four long-relief appearances, Medina pitched 70 2/3 frames with a 4.22 ERA, albeit with shakier secondary marks.

Medina averaged better than 96 mph on his heater and posted a quality 11.4% swinging-strike rate, but those positives were undercut by subpar command. The right-hander walked more than 11% of his opponents, and that lackluster command contributed to a below-average 21.6% strikeout rate that checks in lower than one would expect for a pitcher with Medina’s velocity and bat-missing ability.

Medina will join Waldichuk (flexor strain/UCL sprain) on the injured list to begin the season. That pair’s subtraction from the team’s Opening Day rotation mix creates some additional competition in camp. Oakland has already optioned rotation hopefuls Adrian Martinez, Hogan Harris and Osvaldo Bito to Triple-A. Righties Joe Boyle, Freddy Tarnok, Joey Estes and Royber Salinas are all still in camp and are all already on the 40-man roster. Rule 5 right-hander Mitch Spence is also in the mix for a rotation spot.
