The Athletics placed left-hander Sean Manaea on the 10-day disabled list with a shoulder strain, according to a team announcement on Sunday. The move is retroactive to April 27, when Manaea was lifted from his last start after experiencing shoulder tightness. Manager Bob Melvin told reporters that he only expects Manea to miss one start during his stint on the DL, as the team is planning to utilize right-hander Sonny Gray in his place on Tuesday.
Manaea, 25, has yet to find his footing in his sophomore season with the Athletics. Over five starts, including his abbreviated outing against the Angels last Wednesday, the left-hander carries a 5.18 ERA, 3.28 FIP and 10.0 SO/9 through 24 1/3 innings. Even when healthy, control issues have spoiled some of his more dominant outings, doubling his walk rate per nine innings from the 2.2 BB/9 mark he posted during his rookie season in 2016.
With Manaea due back in the rotation by May 7, the A’s will eventually need to clear roster space to accommodate him. Susan Slusser of the San Francisco Chronicle speculates that the decision could come down to right-handers Jesse Hahn and Jharel Cotton, though the team is still several days away from any formal announcement. Cotton has looked like two wildly different pitchers over his last five starts, tossing two-hit shutouts on his good days and getting shelled with 5-6 runs on his bad days. Hahn, meanwhile, has been a steadier presence in Oakland’s rotation, and his 2.08 ERA and eight-inning shutout should keep him in the majors a while longer, especially if he can replicate those results against the Astros on Sunday.
To the surprise of, well, very few, the Mariners didn’t make the cut for the postseason this year. While they threw their hats in the ring for a wild card berth, their pitching staff just couldn’t stay healthy, from the handful of pitchers who contracted season-ending injuries in spring training to Felix Hernandez‘s shoulder bursitis to structural damage in Hisashi Iwakuma‘s right shoulder. Left-hander James Paxton missed 79 days with a lingering head cold, strained left forearm and pectoral strain. Heading into the 2018 season, the lefty told MLB.com’s Greg Johns that he plans to “nerd out big-time” in order to prepare for a healthy, consistent run with the club.
So far, Johns reports, that entails a new diet and workout program, hot yoga sessions and blood testing. “I just think there’s more I can do,” Paxton said. “I haven’t done the blood testing before. Finding out if there’s something I don’t know about myself. It’s just about learning and trying to find what works for me.”
When healthy, the 28-year-old southpaw was lights-out for the Mariners. He helped stabilize the front end of the rotation with a 12-5 record in 24 starts and supplemented his efforts with a 2.98 ERA, 2.4 BB/9 and 10.3 SO/9 through 136 innings. Despite taking multiple trips to the disabled list, he built up 4.6 fWAR — the most wins above replacement he’s compiled in any season of his career to date. Had he not been felled by a pectoral injury in mid-August — one that came with a five-week trip to the disabled list — the club might have been been able to make a bigger push for the playoffs.
Of course, even if Paxton manages to stay healthy next season, the Mariners still have the rest of the rotation to worry about. They cycled through 17 starters in 2017 and tied the 2014 Rangers with 40 total pitchers over the course of the season. Per GM Jerry Dipoto, their top four starters (Paxton, Hernandez, Iwakuma, and Tommy John candidate Drew Smyly) only contributed 17% of total innings pitched, just a tad below the 40% average. Finding adequate big league arms and compensating for injured aces (both current and former) will be tough. Still, getting a healthy, dominant Paxton back on the mound for 30+ starts would be a huge get for the team — whether or not the postseason is in their future next year.
