Editor's note: Over the next two weeks, we will examine 10 A's players who may or may not return to Oakland next season. For each player, we will provide reasons why the A's should bring him back and reasons why they should not, followed by a final determination.
Ryan Buchter, LHP
Contract: Second year of arbitration (projected to get $1.8 million after earning $1.4 million this season)
Reasons to bring him back
Buchter did exactly what the A's brought him in to do -- retire left-handed hitters. The 32-year-old southpaw limited lefties to a .238 batting average, with 33 strikeouts and seven walks.
Buchter's overall numbers were respectable as well. He went 1-1 with a 2.98 ERA and 1.43 WHIP in 45 1/3 innings. That follows a 6-0 record in 2018 with a 2.75 ERA and 1.20 WHIP.
Reasons to let him go
With MLB changing its rules next season to require a pitcher to face a minimum of three batters, Buchter will lose a lot of value. The so-called LOOGY (left-handed one-out guy) role will disappear and lefty specialists will have to face some right-handers as well.
Right-handed hitter batted .274 off Buchter with 17 strikeouts, compared to 16 walks. While his overall ERA was under 3.00, Buchter allowed 15 of his 36 inherited runners to score, a rate of 41.7 percent. That's nearly 10 points higher than the league average of 32 percent.
Buchter had some good stretches over the past two seasons, but with rule changes and his high walk and hit rate, it's probably time for the A's to move on without him.
Right-handed hitters notched a .904 OPS against Buchter this season in 83 plate appearances. That will be an even bigger problem next year. Oakland can find better relievers for that $1.8 million price tag.
While $1.8 million is an affordable number, Oakland seems unlikely to bring Buchter back in 2020.
